Bahamonde is from Mexico and has cooperated with AAK on several non-standard hydraulic valves. At the beginning of this year, he was stuck by a hydraulic pressure control valve. A hydraulic crank-type lift developed by their company will appear at the exhibition in July. In order to get the test run successful as early as possible, Bahamonde found a local hydraulic pressure control valve manufacturer to make samples. The equipment commissioning was not smooth, and the fluid flow and pressure at the oil outlet of the hydraulic pressure control valve are unstable, resulting in inaccurate positioning of the hydraulic crank-type lift and unstable operation control. The original manufacturer said that the sample was based on the original design. Maybe there are defects in the original design. Bahamonde had contacted several local hydraulic valve manufacturers one after another, but none of them were willing to cooperate in redesigning the hydraulic pressure control valve and making samples. As the exhibition period was about to arrive, Bahamonde was very worried.
Bahamonde thought of AAK because we had the experience of modifying their original design before. According to his hydraulic schematic diagram and the design of the original hydraulic pressure control valve, our engineers have a basic idea after discussing, but it takes time. Bahamonde told me that he could give me 50 days at most. After 3 times of design adjustment and 6 times of simulation, a new design scheme was determined. After 45 days, 30 samples of hydraulic pressure control valves were sent out. 2 weeks later, Bahamonde told me that the test was successful, and asked me to wait for the good news of their exhibition.
Last week, Bahamonde placed an annual order of 1,200 hydraulic pressure control valves, and also mentioned that their hydraulic crank-type lift was very popular during the exhibition. Their engineers admire our technical team's brainy thinking. AAK made it successful this way:
For this hydraulic pressure control valve, we changed the structure of the balance cone valve to the balance plunger type, which can let the pressure, connect the control working port and the pilot control port, control the fluid flow and pressure at the oil inlet, and conduct pilot control at the pilot port. At the same time, the hydraulic pressure control valve acts as the main stage of pressure control. The pilot flow of the valve is very small but the flow capacity is very strong, so the circuit design is flexible. And the newly designed hydraulic pressure control valve can integrate all pressure control circuits with external control functions, such as external control opening, external control closing, multi-stage pressure setting, etc., into the circuit, improving the stability of operation control. Most of the hydraulic valve manufacturers mainly produce standard parts and have no original design capacity. For the non-standard hydraulic valves, basically, they cross the river by feeling the stones.
AAK hydraulic pressure control valve, accurate positioning and high stability, you can also try it!
