  • Hydraulic Cartridge Flow Control Valve - China

    price: 120.00 Dollar US$

    With closed loop controlled Hydraulic Cartridge Flow Control Valve, AAK became Zenon's only choice Zenon is from a hydraulic equipment company in Mexico.

    He has purchased hydraulic components from the United States for 4 years smoothly.

    His boss learned that more and more colleagues are purchasing from China, and also asked Zenon to try to contact China hydraulic valve manufacturers.

    Unexpectedly, he was stumped when he purchased hydraulic cartridge flow control valves the first time.

    At the beginning of the year, their company customized a hydraulic lifting equipment for a customer, which required to use hydraulic cartridge flow control valves.

    Zenon found a hydraulic cartridge valve manufacturer in Ningbo to make samples for the hydraulic cartridge flow control valves.

    During equipment debugging, the lifting positioning was abnormal.

    Their engineer judged that the hydraulic cartridge flow control valve was abnormal.

    After the manufacturer tested the hydraulic cartridge flow control valve, its parameters met the requirements of the drawing.

    Their engineer asked the manufacturer to further optimize the hydraulic cartridge flow control valve, but the manufacturer was unable to do it.

    Zenon had to change the manufacturer.

    After 1 week, no manufacturer was willing to make samples, because there was no direction and great uncertainty.

    The boss has been pushing, and Zenon was under pressure.

    Zenon found AAK on Google, stayed on AAK website for more than 7 minutes, noticed that AAK mainly supplies some big brands of hydraulic cartridge valves in the United States.

    Perhaps he saw the hope from AAK and left a message: 1 - Is the hydraulic cartridge flow control valve the root cause of abnormal hydraulic lifting and positioning?

    2 - Can AAK optimize the hydraulic cartridge flow control valve?

    3 - How long does it take for AAK to customize the hydraulic cartridge flow control valve? AAK website has messages every day.

    For such specific and targeted messages, I always give priority to them.

    After communication, I learned the dilemma of the hydraulic cartridge flow control valves he purchased from the original manufacturer.

    According to the original design drawings and the video of equipment on-site commissioning, AAK engineers believed that the probability of the problem lies in the control mode of the hydraulic cartridge flow control valve, and we have specific plans to optimize it.

    Zenon relaxed and asked AAK to make samples.

    After 30 days, AAK sent 12 samples of hydraulic cartridge flow control valves.

    3 weeks later, Zenon said that the equipment debugging was smooth, and the lifting and positioning were normal.

    The customer was very satisfied with the customized prototype, and would send regular order if there was no abnormality after a trial period.

    I told Zenon that AAK has confidence on the hydraulic cartridge flow control valves, and can wait patiently for the customer's regular order.

    We have facts had proved it.

    For this hydraulic cartridge flow control valve, the valve port flow is not only related to the valve opening area, but also related to the pressure difference before and after the valve port.

    We use closed loop to control the flow of the valve.

    First, connect the spring chamber with the non spring chamber through the flow channel, and set the return spring and the valve spool on the same axis, with one end connected to the valve body and the other end connected to the valve spool for valve spool reset.

    In this way, the flow will not change with the change of load pressure, and the flow of the control system will change with the set value.

    The advantages of such optimization: accurate control, small pressure loss and flexible operation.

    Most hydraulic cartridge flow control valves adopt open loop control, which has low control accuracy, complex mechanical structure and large pressure loss.

    AAK hydraulic cartridge flow control valve has precise control, small pressure loss and flexible operation.
