工作原理：

当②口压力超过开启压力，油液由②流向①反方向①到②关闭。

Pressure at 2 pool over the cracking pressure allows free 

flow from 2 pool to 1 pool Flow in the opposite direction 

from 1pool to 2 pool is blocked.

技术参数：

1.额定压力(Rated pressure):315bar

2.额定流量(Rated flow):150L/min

3.开启压力(Cracking pressure):1 bar

4.泄漏量(Internal leakage):2 drops/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):50~55Nm
