Cristoforo is from an Italian hydraulic equipment company. At the beginning of last year, the hydraulic station they sold to South Africa was complained by the customer in less than half a year. The oil temperature in the hydraulic station was abnormal, as high as 80 ℃, and the efficiency of the whole hydraulic transmission was poor. The after sales service found that the hydraulic relief valve was stuck, which affected the load relief and caused the oil to heat up. The original hydraulic relief valve manufacturer believed that the jamming was caused by unclean hydraulic oil. After detecting the hydraulic oil, there was no abnormality. When disassembling the hydraulic relief valve, it was found that the contact surface between the valve spool and the valve hole was worn, which should be caused by the coaxiality deviation between the valve spool and the valve hole of hydraulic relief valve, resulting in the jamming. The original manufacturer agreed to replace it, but half a year later, the old problem happened again, and Cristoforo was criticized. Cristoforo had to find manufacturers with long service life of hydraulic relief valves. He contacted many manufacturers and found that most of them were not able guarantee a service life of over 1 year for the hydraulic relief valves with a maximum flow of 240L and a pressure of 450bar, but only 6 months. Finally, only 3 manufacturers were willing to test samples, including AAK. AAK engineers determined that the material selection was a key step according to the parameter requirements of the hydraulic relief valve. After 2 months, 30 samples of hydraulic relief valve were sent out. Last week, we received the PO of hydraulic relief valves from Cristoforo. He said that although AAK was the latest to deliver the samples, in the service life test, the hydraulic relief valve samples provided by the 3 manufacturers showed that only AAK had no abnormalities after a service life of more than 1 year. For this kind of customized, high demand and non-standard hydraulic relief valve, our 3 advantages are not available in most manufacturers in Ningbo. 1.The durability of hydraulic relief valve mainly depends on the material selection according to the working conditions. For this hydraulic relief valve, AAK selects 20CrNi2MoV high carburized bearing steel from Germany, combined with carburization pretreatment process, through secondary quenching + cryogenic treatment + low temperature tempering process, it is cooled to 650 ~ 700 ℃ and then discharged after being cooled to 450 ~ 500 ℃. The microhardness is 237 ~ 247 HV, and its wear resistance and contact fatigue performance are increased by more than 3 times. The heat treatment of this material is difficult to control, and most manufacturers cannot control it. 2. In terms of material selection of AAK hydraulic relief valve, there are full-time engineers who use Brinell hardness tester to compare and test various materials under the test conditions of 3000kg force and 10mm ball. Many manufacturers cannot do this kind of material selection method. 3. AAK has a precision honing machine, equipped with diamond reamers, to do a good job in finishing. After honing, the dimensional accuracy of the valve hole of the hydraulic relief valve is IT7 ~ 4, and the surface roughness can reach Ra 0.32 ~ 0.04 microns. AAK hydraulic relief valve, high pressure, large flow, with a service life of more than 1 year, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-relief-valves-aak280

Recently, we launched a hydraulic Solenoid Operated proportional Relief valve equivalent to HydraForce standard part TS10-26. It is a screw-in, cartridge style, pilot-operated, spool-type, relief valve which CAN be infinitely adjusted across a prescribed range using a variable electric current. The regulated pressure is proportional to the input electrical current. Last April in 2022, a hydraulic cartridge valve customer in Canada found AAK when looking for a hydraulic cartridge valve manufacturer in China on Google. He sent us an inquiry for 20 pcs of HydraForce Proportional Relief Valve TS10- 26, with an annual demand of 5,000 pcs. For this model, very few cartridge valve manufacturers in Ningbo have existing production procedures, AAK does not have this model either. Due to big annual demand, customer decided to send AAK original samples to customize it. After 60 days, AAK finished the prototype development and delivered the 20 pcs of test order. This August, we were very happy to learn from the Canadian customer that AAK Proportional Relief Valve E-TS10-26 has passed their internal testing after 1 year of use, they are preparing for the 2024 buy plan and will send us the official order very soon. AAK hydraulic proportional relief valve 2 advantages: 1. Hysteresis per cent ﹤3%, benchmarking HydraForce quality 2.

Last time, a young man came to AAK Hydraulic Valve for interview. He told me: I want to do a big thing, but I always feel like I can do nothing. He has no social resources, is not graduated from famous universities, and his major is also average. This is equivalent to saying that I do not have core competitiveness, but also want results. Why? The world is progressing because a group of people have paid more sweat.   Some hydraulic valve manufacturers always want to find a way to win with one shot, and win big orders, but are not willing to spend energy to really build their core competitiveness. Making money by opportunity dividend does not mean having core competitiveness. At the beginning of e-commerce, many hydraulic valve manufacturers sold hydraulic valves online. When the flow came, they could earn money. However, this is not the core competitiveness of hydraulic valve manufacturers, but just an opportunity. Making money by chance dividend does not mean you have core competitiveness. There is no one way to win in this world. We must be down-to-earth, especially in the manufacturing industry with quality requirements such as hydraulic valves.   Core competence has 3 key words. How to distinguish the peers of AAK Hydraulic Valve from the 3 key words?   1. Relativity, also known as differentiation, is what you have but others don't. For example, AAK has procedures for hydraulic cartridge valves of HydraForce standard and SUN Hydraulics standard parts, and AAK can ship in the quantity of 1 pc.   2.Non-replicability. The core technology is developed by investing a lot of money in the early stage. They are not replicable. For example, AAK Hydraulic Valve has found out a three-step steel heat treatment process by itself. 3. It can bring advantages. You are a hydraulic valve engineer. You say you are very handsome. This is not an advantage in the hydraulic valve industry. It may be an advantage to play movies. AAK Hydraulic Valve, whether for standard parts of big brands, or customized parts of hydraulic valves required by niche market; Whether the sample is copied or the structure is optimized, it plays well.   Core competitiveness is the fundamental reason for manufacturing industry to win customers. As a hydraulic valve manufacturer in the manufacturing industry, why should we have core competitiveness? Difference + advantage + non- duplication, which will bring you high-quality customers and long-term profits. Maybe some people advocate that choice is more important than effort. But I want to say that when the economy goes down, relative competition becomes more important.   The core competitiveness is about equal to the barrier, that is, the moat. Warren Buffett, the god of stocks, said: "If you want to obtain excess profits, you must dig a moat for your company.” The moat, to be honest, is very difficult to dig. But once it is built, it will be very deep and solid. And eventually it will grow and become wider and wider. With a moat, you can stay in the city wall, keep your advantage, and others want to enter, but can't enter. Elon Musk, of Tesla, advocates running all the way. If you run fast enough, the person behind you will not climb over the barrier, but it will not touch you at all. Similarly, it has irreplicability.   For every grass root, the most important way is to run. If the competitors are excellent, the only way is to run faster and faster. Running + barriers is the core competitiveness. The fierce competition is the script of the powerful faction. The script has been written long ago. There is no way to win with one move in this world. You must be down-to-earth and run all the way.   AAK Hydraulic Valve, down-to-earth, runs all the way. https://www.aakindustry.com/info-detai , l/hydraulic-valve-manufacturers-aak486

Andy is one of our old customers of hydraulic valves in Germany. He purchases hydraulic cartridge valves from AAK all year round. Recently, he suddenly asked me some technical parameters of hydraulic valve blocks. I was a little surprised. After further communication, I learned that he started to purchase hydraulic valve blocks for the first time last year, but failed. Andy purchased a batch of hydraulic valve blocks from a manufacturer who just produced hydraulic valves for him in the past. Maybe this manufacturer didn't know enough about the hydraulic valve blocks. After 100 hydraulic valve blocks arrived, there was a problem after sales. According to the user's feedback, the pressure of the hydraulic valve blocks could not meet the system requirements, and the pressure was also unstable. Most hydraulic valve blocks were required to be returned. The manufacturer also said that these hydraulic valve blocks had been tested before leaving the factory. Now these hydraulic valve blocks are stacked in the warehouse. Andy regretted it so much that he was sad all day long. According to the hydraulic valve block drawings, sample photos, and videos provided by Andy, I told him that the processing accuracy of the hydraulic valve block should still be flawed. Although the original manufacturer also did the pressure test, he may not understand that there are 3 types of hydraulic valve block pressure tests, or even he just completed the pressure test on the pressure test bench. This is a common problem in pressure test of most hydraulic valve block manufacturers, but AAK never tests pressure like this. 2 weeks later, I sent 10 samples of hydraulic valve blocks according to his drawings. About 2 weeks later, Andy advised that when AAK hydraulic valve block was installed, the pressure parameters were consistent with the system requirements, and it was smoother and had more stable pressure debugging than that of the original manufacturer. Users liked it very much. Andy disposed of the hydraulic valve blocks in the warehouse and asked us to replenish 100 pieces as soon as possible to fill the inventory. I told Andy that the processing of AAK hydraulic valve blocks will not be falsified in terms of accuracy first and finally in the pressure test stage of hydraulic valve blocks will not be sloppy. The pressure test is carried out directly in the hydraulic system, which is more consistent with the operating conditions than the test on the pressure test bench. At the same time, the test pressure is determined according to the working pressure of the system. However, most manufacturers cannot directly test the hydraulic valve block in the hydraulic system, and directly use the traditional process to test on the pressure test bench. The pressure test of AAK hydraulic valve block is divided into 3 types of standards. Peers may not be able to master the 3 types of methods, and blindly use the test pressure of 1.5 times the working pressure to test whether the pressure of the hydraulic valve block is stable or not. We classify it in this way: for working pressure less than 16MPa, the test pressure is 1.5 times of the working pressure; for the working pressure of 16MPa~25MPa, the test pressure is 1.25 times of the working pressure; at the same time, for the working pressure of 25MPa~31.5MPa, the test pressure is 1.15 times of the working pressure. AAK uses 1.5 times, 1.25 times, 1.15 times to distinguish the only standard 1.5 times of its peers. This detail not only has demons, but also money. It depends on whether you can dig it out. AAK hydraulic valve block, focus on details, more stable pressure, welcome to try. https://www.aakindustry.com/info-d , etail/hydraulic-valve-blocks-aak279

AAK hydraulic pressure control valve has conquered Samuel with 2 million times performance, within 3μm accuracy and 1500H corrosion resistance, with 3 these high differences, winning back the order from Samuel's 5-year old supplier. At the same time, we have also reached a strategic cooperation on hydraulic valves and long-term supply of supporting hydraulic components. Samuel is from a hydraulic equipment company in Italy, and he didn't have much cooperation with AAK in the early stage. At the beginning of the year, they developed a hydraulic cylinder for the solar thermal power generation system in Dubai, and needed to purchase hydraulic pressure control valves. Samuel chose an old supplier who has cooperated for more than 5 years. After 45 days, the hydraulic pressure control valve samples were tested, and it was found that the flow control was unstable. Red rust appeared after more than 500 hours of salt spray test, while Samuel required at least 1,500 hours to adapt to the desert environment of Dubai. The hydraulic pressure control valve manufacturer said that the accuracy is up to standard, and the unstable flow is related to the design. At the same time, the hydraulic pressure control valve adopts the surface treatment of white zinc plating, and the salt spray test should not fail. Samuel was unhappy and had to start looking for a new hydraulic pressure control valve manufacturer. Samuel asked more than 10 manufacturers, but none of them had confidence in the hydraulic control valve with 2 million times of performance used in the desert environment of Dubai. He began to worry at this time, as can be seen from his email to me. He said in his email: I know that AAK has hydraulic flow control valves that are not afraid of high temperature and have been sold to the Middle East, as well as hydraulic counterbalance valves that have not been corroded after a year of sandstorm. I have a hydraulic pressure control valve used in Dubai. No manufacturer is willing to take over. Can AAK make a hydraulic pressure control valve with 2 million times performance used in Dubai? After communication, I learned that the manufacturer he had worked with for 5 years surrendered, and other manufacturers had no intention of accepting orders. I told him that in order to make hydraulic pressure control valve with 2 million times performance used in Dubai, the corrosion resistance of the valve surface must be solved first. Samuel may realize that I have hit the point of the problem, and immediately sent me drawings and other information. Our engineer partially optimized Samuel's original design of hydraulic pressure control valve and told him that for hydraulic pressure control valve with 2 million times performance, within 3μm accuracy and 1,500H corrosion resistance, if the sample of AAK also fails, there is no need to try other hydraulic valve manufacturers in Ningbo, he can just wait for our samples. 45 days later, AAK sent 30 hydraulic pressure control valves. 2 months later, that is, last week, Samuel informed that all the 3 performances of AAK hydraulic pressure control valves had reached the standard, and it was also the only manufacturer that reached the standard. Their team was very happy. Samuel cancelled the PO with the 5 years old supplier and transferred it to AAK. At the same time, we have reached a strategic cooperation on hydraulic valves and long-term supply of supporting hydraulic components. AAK hydraulic pressure control valve can be outstanding with 3 high from peers, which depends on 3 important cornerstones: 1. AAK technical team, adhering to innovation and technical transformation, changed the design for 6 times, and finally determined the optimal design of the inlet and outlet of the hydraulic pressure control valve, that is, the optimal hydraulic control ratio. By means of diversion, the relative balance of the pressure on both sides is adjusted to ensure the smooth operation of the equipment. 2. AAK hydraulic pressure control valve adopts zinc nickel alloy coating, the nickel content is more than 13%, and the corrosion resistance is increased by more than 10 times. Most manufacturers are unwilling to spend this high cost, and also not able to control this special coating process. 3. AAK has produced ODM hydraulic valves for 3 of the world's top 500 for 10 years, and the performance is benchmarked with the international first-line hydraulic valve brands. AAK hydraulic pressure control valve, performance, accuracy, salt spray test, no accident, welcome to have a try! https://www.aakindustry.com/info-detai , l/hydraulic-pressure-control-valves- aak278

Pasternak is the purchasing manager of a Russian hydraulic equipment company. The hydraulic equipment they sold 2 years ago could not be disassembled after 1 year and was requested for after-sales service. During the annual maintenance, it was found that the relief valve hole on the hydraulic manifold was blocked, but the valve was just installed under the motor, and the clearance was less than 3cm. It was difficult to disassemble, so they had to contact the equipment supplier and complained about the improper design of the hydraulic manifold, also unwilling to pay maintenance fees. The after-sales engineer spent 2 weeks to complete the cleaning of the whole hydraulic manifold. Pasternak thought of a customer complainted last month that the hydraulic system pressure was abnormal, but the hydraulic components were normal after inspection. Pasternak realized that there may be problems in the design of hydraulic manifold. If it is not solved, there will be more and more complaints later, and the unlucky one is still him. The original hydraulic manifold manufacturer was not sure where the design deviation was. Pasternak asked more than 10 hydraulic manifold manufacturers, and there was no substantive feedback. Pasternak saw an article about hydraulic manifold of AAK on B2B: Innovative hydraulic manifold design and manufacturing, AAK has no rival in use and maintenance. He sent an email directly to AAK and provided their system schematic diagram and hydraulic manifold design drawings. After analysis, AAK engineers found that the problem really lies in the design of hydraulic manifold. The reasons are as follows: the design of the oil passage direction increases the volume of the valve block, and also causes the loss of oil circuit pressure pipe. At the same time, the selection of hydraulic valves and their installation position on the hydraulic manifold are not optimal. We can redesign the hydraulic manifold and test samples to ensure that the system pressure is stable and the maintenance is simple and convenient. Pasternak realized that perhaps only AAK could help him and paid $2,000 for the development. 1 month later, AAK sent 3 hydraulic manifold samples. 2 weeks later, Pasternak said that the size of AAK hydraulic manifold has been reduced, the installation is convenient, and the hydraulic manifold function is not affected. Last week, Pasternak sent a new inquiry about hydraulic manifold and told me that there had been no customer complaints about unstable pressure in AAK hydraulic manifold samples. Now as long as it was an inquiry about hydraulic manifold, he would email me at the first time. AAK hydraulic manifold is not only smaller than the original design, but also convenient to install, which solves the problem that plagued Pasternak for more than 2 years. There are no complaints in use and maintenance. The customer is satisfied and the boss is happy. Do not be even a little careless in hydraulic manifold design. We first need to determine the selection of components on the hydraulic manifold according to the hydraulic schematic diagram, and draw the sub schematic diagram and three- dimensional model corresponding to the valve block. Secondly, according to the requirements of hydraulic manifold pipe laying, make the overall layout of each component, determine the optimal positions of oil inlet, working port, oil return port, external leakage and external control port, prevent the installation of more than 3 surfaces, especially under the valve block, and determine the size of the valve block according to the maximum overall dimension of the valve preliminarily. Finally, the oil passage on the valve block is designed according to the size and positioning size of the oil port on each valve, so that the internal oil passage is optimally arranged and the pressure loss of the oil passage is minimized. Pasternak told me privately that he would be promoted to purchasing director next month. AAK hydraulic manifold, innovative hydraulic manifold design and manufacturing, AAK has no rival in use and maintenance, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-manifolds-aak277
