工作原理：

当1口压力超过开启压力，油液由1口流向2口，反方向2口到1口关闭。

Pressure at 1 over the cracking pressure allows free flow from

1to 2.Flow in the opposite direction from 2 to 1 is blocked.

技术参数：

1.额定压力(Rated pressure)：250bar

2.额定流量(Rated flow):15L/min

3.开启压力(Cracking pressure):9-10bar

4.泄漏量(Internal leakage):2drops/min

5.油液清洁度(Cleaning code):20/18/15(NAS9)

6.工作温度(Temperature range):-20~+100℃

7.安装扭矩(Installation torque):40~45Nm
