Description<br />
A screw-in cartridge, manually operated, 2-way, 2 position, normally closed,<br />
direct acting, poppet type, intended for use as a bi-directional load holding<br />
device in hydraulic circuits requiring manual operation and low internal leakage.<br />
1<br />
Operation<br />
The WS08WM-01 blocks flow , leakfree, in both directions until an operator<br />
pushes the button against the bias spring and opens the flow path between<br />
port 2 to port 1 bi-directionally. The flow path will be open as long as the plastic<br />
button is pushed down.<br />
Features<br />
• Both ports could be fully pressurized<br />
• Easy to operate manually<br />
• Spring return<br />
• Push type manual override button, protected by rubber cap<br />
