Janice, from Canada, wants to purchase 600 hydraulic relief valves. The core difficulty of this hydraulic relief valve lies in the processing of valve elements. Most factories can only bemoan their inadequacy for the valve elements with inclined holes and included angles. The American hydraulic relief valve manufacturer who has been cooperating with Janice has failed 4 times in 30 days and had to surrender. Janice found more than 20 hydraulic relief valve manufacturers online and offline, at home and abroad, but they either replied that there was no time for sampling or no response. Janice has been tossing about for a week and is a little frustrated. Pablo, an old customer of AAK, after learning about Janice's procurement problems, suggested that she send the hydraulic relief valve drawing to AAK for a try. Pablo also specially wrote me an email to ask AAK to help Janice. I am willing to try to solve such a difficult problem of hydraulic relief valve. Once it is solved, I have won the admiration of two people at the same time. According to the hydraulic relief valve drawing sent by Janice, except for the valve core, other requirements are also conventional. The valve core of this hydraulic relief valve is different from the conventional straight hole valve core, which is marked in the drawing Φ4- Φ3.7mm inclined hole, and the axis line of the Φ3.7mm hole forms an included angle of 60 ° with the axis of the valve core parts. It is difficult and requires high precision in the clamping and positioning process of hole processing. The hydraulic relief valve manufacturers without high-precision equipment and over 15 years old technicians will fail even if they try to make samples for 100 times. AAK technical team discussed for 2 days, and they were 70% confident that the sample would be successful. Although Janice is a little disappointed, it is also the best news she has received recently. She is in urgent need of this hydraulic relief valve. AAK has been brainstorming for 2 weeks, constantly changing the material of the hydraulic relief valve core, adjusting the process parameters, and sending the hydraulic relief valve sample for the first time. After 5 days, Janice informed that there was an error of 0.1% in the inclined hole of the hydraulic relief valve spool. AAK carried out the second hydraulic relief valve sample and optimized the process again on the high-precision turning milling composite locomotive to improve the accuracy of the inclined hole. A few days after AAK's second hydraulic relief valve sample was sent, Janice sent an e-mail. The American manufacturer spent 4 weeks on this hydraulic relief valve, but all 4 samples failed. She tossed and turned for a week and failed to find a hydraulic relief valve manufacturer that dared to make samples. However, AAK succeeded in 2 proofing within 2 - 3 weeks. AAK high-precision turning milling compound machine tool is the core of the success of the sample. This machine tool is equipped with upper and lower tool towers. The main shaft can be 360 ° indexed. The upper shaft is the milling main shaft, with a rotation angle of 225° and 40 tools. At the same time, it can complete the machining of axial hole, radial hole, inclined hole drilling and reaming, inclined groove and tapping under one-time clamping. The key to the success of AAK sample is our old technician, who has 32 years of practical operation experience. With specially assigned person and special machine, AAK has unique skills in turning and milling compound machine tools. AAK hydraulic relief valve, valve element with inclined hole and included angle can also be produced.

Alexandro is from a logistics equipment company in Brazil. At the end of last year, they developed an airport logistics equipment, which will be promoted at this year's exhibition. Unstable pressure supply and slow response occurred in the commissioning stage, because the inlet and outlet oil flow of hydraulic manifold is unstable. Test each hydraulic valve in the hydraulic manifold separately, and there is no abnormality. Their technical team did not have a solution, but only asked Alexandro to re purchase hydraulic manifold. Alexandro knew that blindly re purchasing hydraulic manifold was tantamount to changing the form but not the content. After consulting the manufacturers of the original hydraulic valves and hydraulic valve blocks, they all said that they are unable to analyze the whole hydraulic manifold, but they can ensure that their products have no problems. Alexandro is also consulting other hydraulic manifold manufacturers. A week has passed and no reply has been received. The boss also blamed Alexandro for the poor hydraulic manifold in purchasing, and Alexandro was unable to say the suffering. Alexandro accidentally browsed AAK in Google and left a message: why is the pressure supply of hydraulic manifold unstable? Such questions are not specific and difficult to answer. It is just like the question, what is the cause of a child's fever? A blood test is needed to determine whether it is a virus or a bacterial infection. According to the hydraulic manifold drawings and video of commissioning provided by Alexandro. AAK engineers judge that the problems lie in the design of hydraulic manifold and the selection of hydraulic valves. I replied to Alexandro that AAK can redesign the hydraulic manifold, but it takes 40 days and 6,000 US dollars of development cost. If it fails, the fee can be refunded. The promotion time is coming, the boss is pressing, but he still can not find a new factory. Maybe Alexandro has to only believe in the hydraulic manifold of AAK. After 40 days, AAK sent the hydraulic manifolds. 1 month later, Alexandro informed that the hydraulic manifold newly designed by AAK had been used for 3 weeks, and the equipment was normal. Hydraulic manifold design runs through the whole process of design, manufacturing, use and maintenance, especially affected by manufacturing, that is to say, a good hydraulic manifold design cannot be separated from manufacturing. AAK often receives some hydraulic manifold drawings that cannot be processed directly according to the drawings. A good hydraulic manifold designer must be able to analyze the whole manufacturing process. AAK hydraulic manifold engineers consider not only manufacturing, but also the use, because the design is for "use”, such as hydraulic manifold efficiency, energy consumption, stability, service life, and maintenance methods. Innovation is also needed in hydraulic manifold design. AAK hydraulic manifold innovation means that each hydraulic valve is re combined into a new hydraulic manifold, or some new elements are added to the old hydraulic manifold. New things are generated in affirmation and negation, and negation and affirmation. Innovation is just like seasoning. With such a little seasoning, the dish tastes more delicious. AAK hydraulic manifold runs through the whole process of design, manufacturing, use and maintenance. You can also have a try! https://www.aakindustry.com/info-detai , l/hydraulic-manifold-aak242

Today, Eichendorff from Germany placed a re-order for 500 hydraulic pilot operated pressure control valves and told us that his boss was very satisfied with the quality of AAK. It has been more than 1 year since the last purchase of hydraulic pressure control valves, and no customer complained about unstable pressure supply. At the beginning of last year, one of their hydraulic power units was complained by customers that the pressure supply was often unstable after using a period of time. They judged that there was a problem with the hydraulic pilot operated pressure control valve. After the valve was replaced, the pressure supply of the equipment was normal. Eichendorff sent the replaced valve back to the original hydraulic pressure control valve manufacturer. After inspection, the manufacturer found that the parameters and functions were produced according to the requirements of Eichendorff's company. He thought that they had moved the pressure regulating screw of the hydraulic pressure control valve during installation. After measurement, Eichendorff's engineers found that all parameters of the original hydraulic pressure control valve could be benchmarked, but they did not change the pressure regulating screw during installation. Eichendorff contacted several local German hydraulic pressure control valve manufacturers, and most of them were unwilling to analyze. After browsing AAK website on Google, Eichendorff sent an email and asked: what is the reason for the unstable pressure supply of the hydraulic pressure control valve after using a period of time? AAK HYDRAULIC VALVE often receives similar questions, and we are happy to solve these problems, because this is the best source for accurate customers. Eichendorff sent us the samples, drawings and hydraulic system schematic diagram of the hydraulic pilot operated pressure control valve the next day. 1 week later, AAK engineers disassembled the hydraulic pressure control valve and found 2 possibilities in combination with various technical parameters. First, the design of the damping hole of the hydraulic pilot operated pressure control valve should be improved. The ratio of the opening pressure to the set pressure is a little high, which will cause too large pressure regulation deviation, thus affecting the stability of the valve. Second, the type selection of the spring of the hydraulic pilot operated pressure control valve is not suitable, and a spring with better elasticity is required. After receiving our diagnosis, Eichendorff hoped that AAK could test the samples according to our ideas and was willing to pay the development cost. AAK technical team spent 24 days and tried samples for 6 times, and found the most suitable pressure ratio, adjusted the original design of the damping hole, selected 3 springs with good elasticity to compare, and determined the special SiCr alloy steel spring as the spring of the hydraulic pilot operated pressure control valve. After 30 days, 30 samples were sent. 3 months later, Eichendorff informed by email that when AAK hydraulic pilot operated pressure control valve was used, no customer complained about unstable pressure supply. I replied that according to previous customer feedback, there will be no customer complaint about unstable supply within 1 year. Eichendorff probably didn't believe it until 1 year later, today, the reorder of the hydraulic pressure control valve came. Eichendorff admired AAK service and professionalism from the bottom of his heart. AAK hydraulic pressure control valve is not only professional, but also good at what peers are unwilling to do.

This Monday, we launched a new model E-CXBA free flow nose to side check valve, which is equivalent to SUN's standard parts CXBA. This Free-flow, nose-to-side check valves are on/off circuit components that allow free flow from the inlet (port 1) to the outlet (port 2) and block flow in the opposite direction. Many hydraulic manifolds use this hydraulic check valve, and most hydraulic manifold manufacturers do not have the production procedure of this hydraulic check valve. They need to purchase this hydraulic check valve from other hydraulic cartridge valve manufacturers. AAK has provided this hydraulic check valve to 5 customers for use in their manifolds, or directly supplied the complete hydraulic manifolds with this check valve. This hydraulic check valve is not only widely used, but also has many functional requirements. The key lies in its performance. Although some cartridge valve manufacturers can produce this hydraulic check valve, and perhaps its functions can be compared to SUN's CXBA standard parts, how is the performance of their hydraulic check valve? AAK E-CXBA Hydraulic Check Valve 2 Key Selling Points: 1. The lifespan is twice that of most peers 2. Low leakage, internal leakage of 1 drop/min, benchmarking SUN for both functionality and performance. Technical parameters of AAK E-CXBA Hydraulic Check Valve: Maximum Operating Pressure: 350 bar (5000 psi) Capacity: 10 gpm (40L/min) Internal Leakage: 1 drops/min.

Consuelo comes from Spain and started purchasing hydraulic cartridge valves from manufacturers in China 2 years ago. He has been successful but was wrestled by a hydraulic cartridge relief valve equivalent to HydraForce RV10- 22. The cartridge relief valve thread slipping caused by carelessness in the original hydraulic cartridge valve manufacturer was solved by AAK with 1 small detail. In March of this year, they needed to purchase 100 pcs of hydraulic cartridge relief valves RV10-22. This is a standard part, and Consuelo purchased RV10-22 in bulk directly. 3 months later, some users complained that the threads of the hydraulic cartridge relief valve cage were slipping and leaking. Consuelo was surprised because this is the first time for him to encounter this low-level error of thread slipping. Although the original manufacturer of the hydraulic cartridge relief valve was very cooperative, Consuelo realized that the hydraulic cartridge valve manufacturer with unstable quality would bring him a lot of trouble in his future work. Each hydraulic cartridge relief valve cage thread must be 100% compliant without slipping threads. Consuelo found AAK on Google and left a message: Has AAK encountered any problem with the thread slipping of the hydraulic cartridge relief valve cage? I told him that more than one client has raised the issue of thread slipping, and AAK has avoided thread slipping with just a small detail in the process. After communication, it was learned that he purchased hydraulic cartridge relief valve RV10-22 from the original manufacturer and encountered the problem of thread slipping. I told him that AAK has existing stock for the hydraulic cartridge relief valve RV10-22. He can receive them after 1 week and customer complaints can be resolved. The hydraulic cartridge relief valve thread has no slipping, which is not difficult, but the key lies in the details. Of course, the material selection and processing of hydraulic cartridge relief valves are the foundation. AAK controls the accuracy of the valve cage external thread and internal hole inspection in this way. Before assembly, AAK inspection technicians use thread ring gauges and plug gauges to check. Inspect the thread size on the outer surface of each hydraulic cartridge relief valve cage using a thread gauge. The inner diameter of the hydraulic cartridge relief valve cage is tested with a plug gauge, and each thread is tested. This is a small detail, but most hydraulic cartridge valve manufacturers in China overlook this process directly. The original manufacturer was unable to avoid the thread slipping of hydraulic cartridge relief valve RV10-22, and AAK solved it with one 1 small detail. AAK hydraulic cartridge relief valve, the thread without slipping, you can rest assured to give it a try!

Albion is from Turkey, and has cooperated with AAK on hydraulic manifold blocks for 2 years. In the second half of last year, they received a sample order for hydraulic manifold blocks, and the customer requested to deliver the samples within 60 days. For hydraulic valve standard parts, this time frame is OK. However, for the customized hydraulic manifold block, it is some difficult to finish in 45-50 days. Albion contacted a local hydraulic manifold block manufacturer, but after receiving the drawings, the manufacturer said it was too late. Because this hydraulic manifold block has a high degree of integration, many types of cavity holes, multiple machine tool positioning, complex processing, and the need for customized molding tools, it needs at least 60 days. Albion has contacted more than 10 hydraulic manifold block manufacturers, none of them can catch the schedule. Albion was worried. Albion contacted me and asked about the sample lead time. Can AAK complete the hydraulic manifold block sample within 45-50 days? According to the analysis of AAK engineers, the processing of this hydraulic manifold block is really difficult. According to the conventional processing technology, it will take at least 60 days. AAK has a unique processing technology to sample this hydraulic manifold block, and can complete it in 45 days. Albion was very happy to learn it. AAK sent 3 samples of hydraulic manifold blocks 45 days later. 3 weeks later, Albion informed that AAK sample of hydraulic manifold block was sent to the customer. Thanks to AAK for completing the hydraulic manifold blocks in 45 days, but it seems that it is not the traditional processing method. For the sample of this hydraulic manifold block, AAK does not need a forming knife, and uses a simple and time-saving method to sample. 1. In the hydraulic manifold block, first drill and tap the installation hole and oil passage hole concentrically. There are grooves in the installation hole. There are eccentric positioning pin holes at the bottom of the installation hole. During installation, the fixed groove is sleeved into the opening ring and pressed to the same outer diameter as the valve hole to ensure the size and accuracy of the cavity hole. 2. The layout of the oil passage groove is based on the method of electronic printed circuit and plane machining, and the cover plate is welded by brazing. This method is more convenient and time shorter than conventional drilling. 3. The installation hole of the hydraulic manifold block is drilled, expanded, milled, bored and processed. The oil ports in the valve hole are distributed axially through the oil guide groove, leading to the connection position of the oil passage groove on the oil passage plate. In this emergency processing method, to sample the hydraulic manifold block is a surprise. There is no need for customized tools, which saves time, simplifies processing, and does not affect the hydraulic manifold block to support the hydraulic manifolds. AAK hydraulic manifold block, the sample lead time is only 70% of that of peers, you can also have a small test. https://www.aakindustry.com/info-deta , il/hydraulic-manifold-blocks-aak477

Primo is from a hydraulic equipment company in Brazil. He has been smooth in this industry for 5 years, but encountered trouble in a hydraulic cartridge directional control valve. At the beginning of this year, their company sold a batch of hydraulic supports. After 6 months, the customer reported that the pipeline interface was suddenly broken. The after-sales server thought it would be OK to replace the pipes, but a week later, an accident was almost caused and the customer was angry. The original source is the hydraulic cartridge directional control valve. When the control valve is opened in reverse direction, the system oil overflows rapidly with a large amount, and the impact pressure causes the fracture of the pipeline interface. The manufacturer of the hydraulic cartridge directional control valves fed back that the high pressure and large flow under operating conditions caused abnormal control, which had nothing to do with the manufacturing quality of the valves, the only solution is to replace with new ones. Primo had no choice but to change the manufacturer of the hydraulic cartridge directional control valves. A week has passed but the after-sales plan has not been implemented yet. The boss was unhappy and Primo was worried. Primo found AAK on Google. After browsing AAK website, he left a message: How to ensure the stability of the hydraulic cartridge directional control valves with high pressure resistance and large flow? After communication, I learned that the original hydraulic cartridge valve manufacturer had no solution. I told him that AAK hydraulic cartridge directional control valve should first ensure its reliability, not replace the pipeline interface today, but replace the seal ring tomorrow, and then ensure its stability, it cannot be the case that sometimes it is abnormal, sometimes it is normal. Perhaps Primo felt that AAK was different from the other China hydraulic cartridge valve manufacturers he contacted, and asked if we could make samples according to the hydraulic cartridge directional control valve drawing and system schematic diagram provided by him. AAK engineer thought that the design of the hydraulic cartridge directional control valve should be optimized first. Primo’s engineer said that AAK can play its own role as long as the appearance and size remain unchanged and the functions are satisfied. After 50 days, AAK sent 12 samples of hydraulic cartridge directional control valves. 2 weeks later, Primo emailed that the hydraulic support could operate normally after installing AAK hydraulic cartridge directional control valves. Next, he just needed to wait for his customer to assess the stability of the hydraulic supports. I told him that he does not need to worry about the stability of AAK hydraulic cartridge directional control valves, even under high pressure and large flow, there would be no problem in 1 year. Last week, Primo sent the order for 360 hydraulic cartridge directional control valves, reminding me that this was the request of his boss. In order to avoid accidents, the boss decided to replace all the hydraulic supports with AAK Hydraulic cartridge directional control valves, because the customer was very satisfied with this after-sales plan, the hydraulic support has been used for 9 months without any abnormality. AAK hydraulic cartridge directional control valve, is resistant to high pressure and has large flow, focuses on stability and reliability, and is optimized from the following 3 points. It has impressed Primo who has been in purchasing for 5 years, and also impressed his engineers and boss, making customers more satisfied. 1. Optimize the opening of hydraulic cartridge directional control valve spool. The bigger the opening, the weaker the impact of system oil shock and fluid energy. But this opening must be moderate. If it is too large, it will backfire. Here's the trick. 2. Using the dynamic characteristic curve, the best matching between the oil pressure and the half cone angle of the small valve spool is refined. The suitable half cone angle of the small valve spool can effectively reduce the pressure impact and increase the stability during the opening process. 3. At the outer side of the large diameter end of the valve spool and at the beginning of the threaded connection on the inner wall of the valve body, a stop ring is set, which is also conducive to the stability of the hydraulic cartridge directional control valve. AAK hydraulic directional control valve, under high pressure and large flow, has twice the stability of its peers.
