ball check valve / spring / hydraulic

Check valves are a type of non-return valve. They block the oil flow in one direction and open in the opposite direction. In the closed state they have zero leakage.

The check valve type ER can be plugged in. The spring-loaded ball check valve type ER is very robust and insensitive to soiling.

Type ER can be integrated directly in valves for manifold mounting. As such an additional intermediate plate is not necessary for the check valve function.
