This week, we launched a new model equivalent to HydraForce SP08-20 SOLENOID PROPORTIONAL VALVE, NORMALLY CLOSED. At the beginning, we were also hesitant to develop, because currently none of a domestic hydraulic cartridge valve manufacturer in China can benchmark the standard of HydraForce SP08-20, especially the internal accuracy of the magnetic guide sleeve inside the valve, which is not only a high-end device that can solve. I know that as long as I promise to develop SP08-20 for customer, it will be accompanied by late night lights. As long as one detail is not in place, the characteristic curve cannot 100% benchmark HydraForce. I told my engineer that when developing SP08-20, my mindset is: Don't ask about harvest, but ask about cultivation. Take the time to try, and leave the rest to luck. Fortunately, AAK spent 6 months, 3 times material changes, 4 times testing samples, and finally achieved the standard of HydraForce SP08-20 SOLENOID PROPORTIONAL VALVE successfully. The characteristic curve is 100% benchmarking HydraForce, and there is no second one in China now. This is God's favor for AAK. AAK E-SP08-20 SOLENOID PROPORTIONAL VALVE, 2 main features: 1. Low leakage, internal leakage 5 drops/minute. 2. Performance benchmarking HydraForce, Ningbo has no second manufacturer SPECIFICATIONS: Max.

The XX hydraulic manufacturing company in Germany has been rooted in the hydraulic system equipment of the airport for many years. A batch of hydraulic pressure reducing valves purchased by the novice Carla at the beginning of the year were repeatedly complained by the airport, which brought a lot of losses to the company's after-sales service and alerted the boss. In the first half of last year, Carla’s company sold hydraulic power units to Malaysia, which is used to supply emergency fuel to aircraft at the airport. The equipment was reported for repair after running for about a month. The after-sales engineer handled it at Kuala Lumpur Airport and locked the abnormality of the hydraulic pressure reducing valves according to the fault code. Finally, it was found that the sealing ring of the hydraulic pressure reducing valves was corroded, affecting the operation of the equipment. The engineer asked Carla to mail the new sealing ring to the site within 2 weeks. The manufacturer of the original hydraulic pressure reducing valves learned that the sealing ring was seriously corroded and was willing to replace with fluororubber sealing rings, which have the best corrosion resistance, for free. The manufacturer also reminded Carla that when she placed the order, the medium used in the hydraulic pressure reducing valves was not specified, so the conventional nitrile rubber sealing rings were equipped. Considering that Carla is a novice, he is willing to offer replacements for free. Carla thought that the abnormal hydraulic pressure reducing valves were solved in this way. Unexpectedly, the same problem occurred only two months after the replacement. The customer was angry and said that if the second after-sales service still couldn't solved the problem at one time, all the equipment would be returned. Carla went to the original manufacturer of hydraulic pressure reducing valves again, and the manufacturer gave up, because the fluororubber seal ring was their best choice. Now Carla was worried and had to turn to her purchasing director for help. The director asked her to contact AAK hydraulic valves first. If AAK still cannot solve it, there will be no need to waste time on Chinese hydraulic pressure reducing valve manufacturers and can only purchase from Germany. After receiving the email, AAK replied that she should not worry. According to the drawing parameters of her hydraulic pressure reducing valve, it matches a hydraulic pressure reducing valve used in aircraft completely that AAK produced for a Russian customer reorder some time ago. We still have some quantity in stock, and can ensure that AAK hydraulic pressure reducing valves will not be reported for repair for at least one year. The next day, AAK sent 10 hydraulic pressure reducing valves to Kuala Lumpur Airport. Carla emailed us a few days ago that after using AAK hydraulic pressure reducing valves, the equipment has been running smoothly for 6 months, while the ones from the original manufacturer were reported for repair in 2 months. She was surprised by the sealing ring of AAK hydraulic pressure reducing valves. AAK can't be careless in details. Like the original manufacturer, not to check the use medium of the hydraulic pressure reducing valves, but ship order blindly, this is zero tolerance for AAK. The aircraft hydraulic system uses highly corrosive aviation blue oil. Even the fluororubber sealing ring considered as the best by most manufacturers is still not suitable for this medium. Three years ago, AAK tested for many times and found that EPDM seal ring is the most suitable for aviation blue oil medium. Its special molecular structure is highly chemically stable, especially the anti-aging property is several times that of fluorine rubber. This is also the reason why Russian customer has been reordering the hydraulic pressure reducing valves on aircraft from AAK. AAK hydraulic pressure reducing valves have tips on sealing rings, which can be used in the airport. Peers can't think of it. You are welcome to give it a try! https://www.aakindustry.com/info-detai , l/hydraulic-pressure-reducing-valves- aak201

AAK unique 5 steps sand cleaning method replaces the traditional method commonly used by peers, and completely solves the problem of valve stuck or filter blockage of hydraulic relief valves caused by hidden danger in sand cleaning. The American customer placed an order for the hydraulic relief valves to AAK 3 days after the test run. Most of the bodies of the hydraulic relief valves are made of nodular iron, vermicular iron and gray iron and cast by sand turning with resin sand as the modeling medium. Therefore, there is sticky sand in the casting, which is easy to cause valve jamming and filter blockage. Most of the common sand cleaning methods of hydraulic relief valves in the same industry are shot blasting and electrochemical sand cleaning. These methods have limitations and are not conducive to the stability of hydraulic relief valves. Gabriel is a purchaser of a hydraulic company in the United States. In previous years, he purchased the hydraulic relief valves in the United States. Recently, there is an order for hydraulic relief valves. The production of the original domestic manufacturer is full schedule, while the other hydraulic relief valve manufacturers dislike the small quantity and are unwilling to accept the order. The company asked him to check with Chinese hydraulic relief valve manufacturers. Among several hydraulic relief valve manufacturers recommended by his colleagues, Gabriel chose 3 of them to send samples after a round of comparison. After 20 days, the samples of these 3 hydraulic relief valve manufacturers were generally stable and prone to valve jamming or filter blockage. The root cause was the incomplete sand cleaning process of the hydraulic relief valves. When browsing B2B websites, Gabriel saw that AAK website www.aakindustry.com introduced the 5 steps sand cleaning method of hydraulic relief valves. He left a message on our website: Can AAK make the hydraulic relief valves not stuck or the filter not blocked? We replied him directly: AAK hydraulic relief valves with 5 steps sand cleaning method have been recognized by German customers. You are welcome to try the order. Gabriel subconsciously approved AAK hydraulic relief valves but was still some concerned because of no cooperation before, so he asked for samples to test first. According to the draft of hydraulic relief valves sent by him, we sent samples in 2 weeks. Gabriel issued official PO on the 3rd day after receiving the hydraulic relief valve samples for commissioning, and requested that the bulk goods to be 100% sand cleaned thoroughly. AAK adopts more efficient sand cleaning method and has its own unique 5 steps sand cleaning method for small and complex castings, namely: Artificial aging - Pickling - Rinsing - Rust prevention - Ultrasonic cleaning. Artificial aging is used to reduce the binding force between the casting and sand, acid pickling is used to remove the oxide skin at the joint between the sand and the casting, so as to peel the sand off the casting, and then the explosion of compressed air during ultrasonic cleaning is used to make the sand fall off, so as to achieve the purpose of 100% sand cleaning. Gabriel issued the PO in 3 days after receiving AAK hydraulic relief valves for testing. This is a witness of AAK unique sand cleaning methods. AAK hydraulic relief valves do not block the valve or filter, which is due to AAK unique 5 steps sand cleaning method. You can also have a small try. https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak200

Nicholas is from an Italian hydraulic company. Last year, a batch of hydraulic equipment needed to use the hydraulic check valve urgently. Due to tight time, Nicholas purchased in Italy. After installing the local hydraulic check valve, the equipment commissioning was normal, but 3 months later, some users complained that the pressure of the power unit was insufficient. It was found that the hydraulic check valve was stuck on site, resulting in weak pressure supply of the system.    Nicholas contacted the original hydraulic check valve supplier and the supplier replied that the jamming was caused by unclean hydraulic oil. The on- site personnel found that the hydraulic oil was polluted, so they could only disassemble and clean the stuck hydraulic check valve. After replacing the hydraulic oil of the whole system, the equipment returned to normal. But a few months later, the same problem happened again, and Nicholas's after-sales personnel operated again as last time. The boss felt that the problem should be solved fundamentally after he knew it. Such after-sales cost is too high. Their engineers fed back that they could only install the filter screen at the inlet of the hydraulic check valve, but the original design of the equipment did not consider the position of the filter screen. It will cost more to refit the whole set of equipment.   The boss asked Nicholas to contact more local hydraulic check valve manufacturers to brainstorm. After knowing the problem with this hydraulic check valve from Nicholas, and the hydraulic oil is inevitably polluted, combining with their equipment working conditions and installation drawings, I told him that we can only find hydraulic check valve with filtering function. AAK has similar hydraulic check valve with automatic filtering function. Nicholas doesn't believe that AAK can provide such a hydraulic check valve. After receiving AAK sample and installing it, the equipment works normally. Nicholas asked us how long AAK hydraulic check valve with filter screen can work? We told him that there would be no users to apply for repair within 1 year.   Nicholas asked why we are so confident. I told him that a Canadian customer had the same problem last year. We developed this new hydraulic check valve. Within one year, Canadian customer has not reported that there is a problem with this hydraulic check valve yet. Half a year later, Nicholas sent an email saying that his customers had never changed the hydraulic oil after using AAK hydraulic check valves.   At that time, in order to save the installation space of filter plug-ins for the hydraulic system of Canadian customer, not to use bulky filter containers, and keep the system clean and extend the service life of hydraulic check valves, AAK designed a hydraulic check valve with filter embedded into the body, that is, the filter screen and the hydraulic check valve are installed in the valve block together. The filter made of 304 stainless steel can effectively remove the fine particles in the hydraulic oil, and it is no longer necessary to change the hydraulic oil once every 3 months.   AAK hydraulic check valve with filter screen saves money and worry.

Derya is from Türkiye. Most of the customers in Türkiye who contact AAK are dealers of hydraulic cartridge valves, but Derya operates a hydraulic equipment manufacturing company. At the beginning of this year, they developed an aviation hydraulic power unit that requires high-precision hydraulic cartridge directional control valves, especially the surface finish of the valve spool to be controlled within Ra0.3. Derya customized the hydraulic cartridge directional control valve with a manufacturer in China that had been cooperating for 3 years. 2 months later, the debugging of the aviation hydraulic power unit was not smooth, due to the insensitive opening and closing performance of the hydraulic cartridge directional control valve and equipment operation hysteresis. The engineer found that the surface finish of the hydraulic cartridge directional control valve spool from the original manufacturer exceeded Ra0.5. The original hydraulic cartridge valve manufacturer stated that they can only produce more valve spools and select them one by one. Derya realized that the manufacturing quality of the original hydraulic cartridge valve manufacturer was unstable, so he had to choose a new manufacturer for the hydraulic cartridge directional control valve. However, 2 months had passed since then, Derya was in a hurry. Derya found AAK on Google and left a message: 1. How long does it take for AAK to customize the hydraulic cartridge directional control valve? 2. Is it possible for AAK to control the smoothness of the valve spool of each hydraulic cartridge directional control valve within Ra0.3? After communication, it was learned that he was facing the dilemma of customizing a hydraulic cartridge directional control valve. I provided him a customer case of a hydraulic cartridge directional control valve previously customized for a Russian customer, with a surface finish of Ra0.2 on the valve spool and a video of how we handled the surface finish of the valve spool. Derya had no concerns anymore and requested AAK to make samples. After 50 days, AAK sent 20 samples of hydraulic cartridge directional control valves. 4 weeks later, Derya informed us via email that their aviation hydraulic power unit had been successfully tested and was on its way to deliver to the customer. The smoothness of the AAK hydraulic cartridge directional control valve spool was controlled at Ra0.2 and satisfied their engineers. For AAK hydraulic cartridge directional control valve spool components, the first is to choose suitable materials. For this model, we use 20CrNi2MoV high permeability carbon bearing steel, which has wear-resistant performance and can better protect the smoothness of the valve spool. Then it is polished and precision processed, and AAK uses a Taiwan centerless grinder. The process setting for centerless grinding is done by AAK this way: Firstly, the surface error and feed speed of the grinding wheel are set, and the surface error value of the hydraulic cartridge directional control valve spool is set to within 2μm, the feed speed of the grinding wheel is set at 400mm/min. The relative vibration between the grinding wheel and the valve spool, as well as the contact stiffness between the valve spool, guide wheel components, and support plate, can be more smoothly controlled, ensuring that the surface finish of each hydraulic cartridge directional control valve spool can be controlled within Ra0.2 after processing. AAK hydraulic cartridge directional control valve, the spool smoothness controlled within Ra0.2, you can also give it a try!

A few days ago, Titan, an old customer from Türkiye, sent me 6 samples of hydraulic cartridge valves. According to his description, there were 3 batches of the valves purchased from the original hydraulic cartridge valve manufacturer, and 2 batches of valves had abnormal service life. Some hydraulic cartridge valves had a service life of more than 1 million times, while some hydraulic cartridge valves had only about 700,000 times. However, no problem could be found in the selection of materials or accuracy of hydraulic cartridge valves. The original manufacturer of the hydraulic cartridge valves is also uncertain about the root cause of the problem, which has made Titan very upset. There are various possible reasons for unstable service life, such as material selection, machining accuracy, internal structure of the valve, and accessories. According to our testing, the valve provided by the original hydraulic cartridge valve manufacturer is unstable due to the quality of the spring, which affects the service life of the hydraulic cartridge valve. Titan mentioned that the Korean piano steel wire material used by the original hydraulic cartridge valve manufacturer should have a service life of no less than 1 million times. Yes, it is the basic standard for high- quality hydraulic cartridge valves to use piano steel wire. However, there are details on where the spring is processed and how to test its service life. Most hydraulic cartridge valve manufacturers just purchase springs from processing plants and then assemble them directly. Once there is a quality problem in the spring factory, it also affects the hydraulic cartridge valve manufacturers. Hydraulic cartridge valve manufacturer AAK controls the quality of springs through material selection and testing, based on 3 details: 1.The selection of piano wire is inevitable. 2.The length of the spring must be measured using a caliper, with the unit focused in millimeters. 3.The service life of the spring is controlled by specialized equipment. As shown in the video, hydraulic cartridge valve manufacturer AAK requires each batch of springs to undergo durability fatigue testing using a spring life testing machine. After the spring is inserted into the fixture, select the working mode in the program first, and then set 1 million tests to set the amplitude and frequency of the spring. Adjust the distance between the upper and lower pressure plates according to the length of the spring. After starting the equipment, the reciprocating motion of the connecting rod drives the compression work of the spring. The time and frequency of spring operation can be tracked on the screen at any time. If the spring is less than 1 million times, the program will automatically remind. AAK hydraulic cartridge valve has a service life of over 1 million times, which is the most basic requirement. You can also give it a try!
