DSV/DSL PILOT OPERATED CHECK VALVES
DSV/DSL pilot operated check valves allow free flow in one direction and block flow in the counter direction to maintain presure. The oil is allowed to flow in
the counter direction when the X port is connected.
DSV is designed for internally drained, DSL is designed for externally
drained. |
