SV_SL Pilot Operated Check Valves

SV/SL pilot operated check valve allow free flow in one direction and block flow in the counter direction to maintaining presure. The oil is allowed to flow in the counter direction when the X port is connected. The pilot oil can also flow in the counter direction when the pilot port X being connected. SV is designed for internally drained. SL is designed for externally drained.
