  • Hydraulic Cartridge Proportional Valve Precise Control - China

    price: 80.00 Dollar US$

    For the Hydraulic Cartridge Proportional Valve with Small Pressure Loss and Accurate Control, AAK has no competitor Brandon is from a hydraulic equipment manufacturing company in Colombia.

    In the early stage, they developed a forging hydraulic press.

    The main selling point is: high speed when unloaded, and low speed when overloaded.

    The engineer has high requirements for the hydraulic cartridge proportional valve used and reminded Brandon to find a reliable manufacturer of the hydraulic cartridge proportional valves.

    Brandon chose a manufacturer who worked with their company for 5 years to sample the hydraulic cartridge proportional valve.

    During testing, the equipment was not smooth, especially in the process of pressure relief, the pressure and flow impact was large, the noise was loud, and the abnormal flow lead to the unstable speed of the equipment.

    The engineer required that the hydraulic cartridge proportional valve must be optimized.

    The original manufacturer had to give up after 30 days of trying, and Brandon was worried.

    Brandon clicked on AAK's article about hydraulic cartridge proportional control valve in B2B and left a message: Can you customize a hydraulic cartridge proportional valve with small pressure impact and accurate flow control? After communication, we learned that the original cartridge valve manufacturer could not optimize the structure.

    After checking his hydraulic cartridge proportional valve drawings and equipment work videos, I told him that optimizing structure was the only solution, but not 100% confidence, then no further email from Brandon.

    2 weeks later, he suddenly asked about the lead time and development cost for the customization.

    After 35 days, AAK sent 8 hydraulic cartridge proportional valve samples.

    1 month after the samples were sent, Brandon sent an email to inform that their engineers were very satisfied with the hydraulic cartridge proportional valve optimized by AAK, and the equipment was successfully debugged and was in market promotion stage.

    They believed that the pre-sales would not be low.

    AAK hydraulic cartridge proportional valve can ensure small pressure impact and accurate flow control during pressure relief.

    We optimized it as follows: 1 - 4 symmetrical waist shaped holes were processed on the valve sleeve, which can reduce the pressure impact and sudden change of speed of the oil near the valve port, and also reduces the energy loss of the oil in the flow process.

    Most hydraulic cartridge proportional valve manufacturers use round holes, which are easy to process.

    2 - The displacement of the valve spool is controlled by the pilot control mechanism.

    The oil flows into the two closed areas composed of the valve spool, the control cover plate and the valve sleeve through the control cover plate, and the valve spool moves up and down through the differential pressure of its oil.

    3 - The valve cover is equipped with a displacement sensor to detect the displacement of the valve spool in real time, and the high-precision linear control can meet the characteristics of flow gain and smooth flow, and reduce the pressure impact during the pressure relief process.

    AAK hydraulic cartridge proportional control valve, with small pressure loss and precise control, you can also have a small try! AAK HYDRAULIC CARTRIDGE VALVES (422) 2022-11-26
