  • Hydraulic Cartridge Proportional Control Valve - China

    price: 60.00 Dollar US$

    AAK Hydraulic Cartridge Proportional Control Valve with Dual Flow Control, Timon couldn't find a second manufacturer Timon is from a hydraulic equipment manufacturing company in the Netherlands.

    He has been smooth on purchasing hydraulic cartridge valves from China.

    A hydraulic cartridge proportional control valve he purchased in the second half of last year was in trouble.

    For a customer, they customized a hydraulic forging presses, which require high speed when unloaded and low speed when overloaded.

    The key to the stability of the hydraulic system and the stepless speed control of the equipment is the hydraulic cartridge proportional control valve.

    Timon worked with a manufacturer of hydraulic cartridge proportional control valves who has cooperated with them for 3 years to try samples.

    During equipment commissioning, the main working cylinder had abnormal pressure relief, which would seriously affect the service life of the equipment.

    After several rounds of inspection, the problem was locked in the structure of the hydraulic cartridge proportional control valve, but the original manufacturer was unable to optimize it.

    Timon contacted more than 10 hydraulic cartridge valve manufacturers.

    A week passed, but there was no solution.

    Their engineer has push for progress 3 times.

    Timon found AAK Hydraulic Valve on Google, stayed on our website for 11 minutes, and left a message:

    1 - Can AAK optimize the structure of a hydraulic cartridge proportional control valve?

    2 - Can the optimized hydraulic cartridge proportional control valve improve the large pressure impact of the hydraulic system?

    3 - What is the lead time and development cost for customizing the hydraulic cartridge proportional control valve? After communication, we learned about Timon's procurement dilemma.

    After checking the system schematic diagram and original design drawings of his hydraulic cartridge proportional control valve, AAK engineers understood the direction of optimization.

    When Timon learned that AAK was 90% sure to be successful, he asked us to make samples.

    After 30 days, AAK sent 10 samples of hydraulic cartridge proportional control valves.

    3 weeks later, Timon said that the equipment had been delivered to the customer, and their engineers were very satisfied with AAK hydraulic cartridge proportional control valve, which completely solved the problem of large pressure impact in the hydraulic system of the forging press.

    AAK hydraulic cartridge proportional control valve can accurately control small flow and large flow, with small flow fluctuation and small pressure impact.

    The key is that AAK hydraulic cartridge proportional control valve has the function of variable flow gain.

    The structure is that the lower part of the hollow valve spool is put into the valve cage and sealed with the valve cage line.

    The upper part of the hollow valve spool is matched with the control cover plate.

    The upper end of the control cover plate is connected with the valve cover, and the valve cover is equipped with a displacement sensor.

    A pilot control valve is installed on the side of the control cover plate.

    The port at the bottom of the valve spool is processed with a semicircular hole, and the valve cage is provided with 4 symmetrical waist holes.

    With the optimized structure, when the opening of the hydraulic cartridge proportional control valve is small, the flow gain is small, and high-precision linear control of small flow can be realized.

    When the opening amount is large, the flow gain is large, and high-precision linear control of large flow can be realized.

    Under the high-precision linear control of large flow, the hydraulic cartridge proportional control valve has small flow fluctuation, small pressure impact, and the service life of the valve is increased by at least 30%.

    AAK hydraulic cartridge proportional control valve, variable flow gain function, you can also have a small try! AAK HYDRAULIC CARTRIDGE VALVES (411) 2022-11-15
