EXTERNAL SINGLE PILOT OPERATED CHECK VALVES

Use and Operation
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 mounting enables valves to be insensitive to back pressure on the line V. Assembly on 2 or more parallel cylinders with a flow regulator valve to allow balanced and soft descent is highly recommended.
