SC Series Hydraulic Single Pilot Operated Check Valves are used to block the cylinder in one direction until pilot pressure applied.
The flow is free in one direction and reverse flow is blocked. When the pilot pressure is applied
to X port it allows the return flow.
SC Series are commonly used for keeping cylinders leak-free in position, when spool type directional control valves are used; as hydraulically activated recirculation or drain valve; and for discharge of return line, when flow exceeds limits of directional control valve.
