SINGLE PILOT OPERATED CHECK VALVES WITH SEPARATE PILOT
These valves are used to block the cylinder in one direction. The flow is free in one direction and blocked in the reverse one until pilot pressure is applied. Separated pilot enables the valve to be insensitive to the back pressure on line V2. Assembly on 2 or more parallel cylinders with a sequence valve to allow balanced and soft descent is highly recommended.
