技术参数 Specifications |
|
当P口压力达到设定压力后，先导阀芯首先被打开，
由此产生的压差使得主阀芯打开，P到丅实现溢流。 该类型的阀反向可以承受一定的背压，启闭率较高， 适用于高压力、大流量的液压系统。 When the pressure at "P"reaches the valvesetting,the pilot spool starts to open , Next the main spool opening because of the pressure drop between inside and outside of main spool, Realizeoverflow from P fo T. This type of valve can withstand a certain amount of back pressure,has high opening and closing rate Suitable for the hydraulic system of high pressure and large flow
