The Valve is designed for precise control in pneumatic control circuits. It can be used as a relay valve to sequence-specific signal operations or as a relief valve to limit pressure in a pneumatic system.

Fixed or adjustable pressure settings are available; the pressure range is 0-20 PSI. To adjust the valve, turn the adjusting screw clockwise to reach zero adjustments. Then turn the adjusting screw counterclockwise to the desired relieving or sequencing pressure.
