工作原理

DESCRIPTION

技术参数 

Specifications

由此产生的压差使得主阀芯打开，P到丅实现溢流。该

类型的阀一般具有较高的启闭率，内泄漏小，适用于高

压力、大流量的液压系统。

 pilot spool starts fo open,Next themain spool opening because

of the pressure dropbetween inside and outside of main spool,

 Realizeoverflow from P to T.This type of valve generallyhas high

 opening and closingrate ,very low interna!leakage, Suitable for

 the hydraulic system of highpressure and large flow

    2、额定流量(Rated flow):60L/min

    3、开启率(Cracking Rate) ：>90%

    4、合率(Closing Rate)：>84%

    5、补油开启压力(Anti-CavCracking Pressure):0.55bar

    6、内泄漏(Internal Leakage) ：<5ml/min at 106.5bar

    7、油液清洁度(Cleanling code):20/18/15(NAS9)

    8、工作温度(Temperature range):-20~+100℃

    9、每转压力变化(Pressure change per turn):56.9bar

    10、安装扭矩(lstallation Torque):40~45Nm

    11、锁紧扭矩(Nut Tightening Torque):18~32Nm
