Hydraulic system cartridge valve advantages:
① Can achieve high power control, small pressure loss, small heat. On the one hand, due to the use of two-way cartridge valves, many pipelines are reduced, and the loss along the way is small; On the other hand, the pressure loss of a single cartridge valve unit (logic valve unit) is greatly reduced compared with the conventional valve of the same caliber. And through the conventional valve can not match the large flow, conventional hydraulic valve simply can not have such a large flow (high power) products. This flow capacity is unimaginable for conventional valves, so cartridge valves are suitable for high pressure, large flow and high power hydraulic systems.
② Cartridge valve is mainly composed of logic unit (cartridge), it has been standardized, can be organized specialized manufacturers production, conducive to mass production, can reduce costs and professional production, so as to improve product quality, design can also be easy to choose.
No high-speed reversing impact: this is the most prone to headache in high-power hydraulic systems. Because the cartridge valve is a compact conical valve structure, the control volume is small when switching, and there is no "positive cover" concept of the slide valve, so it can be switched at high speed. By taking some measures for the components of the pilot part and adapting to the transition state control during the switching process, the reversing impact can be greatly reduced during the switching.
(4) With high switching reliability: the general cone valve is difficult to cause bad action due to dirt, small pressure loss, small heat, and the spool has a long guide part, which is not easy to produce skew stuck phenomenon, so the action is reliable
