Pneumadyne’s new Pilot Operated Check Valves are ideal for reliably holding an actuator position in a variety of applications. They are designed for use in applications requiring an actuator to be locked in position. These rugged valves feature a 1/4 NPT output port which mounts directly on a cylinder, minimizing space requirements and easing tubing installation. The input port swivels to accommodate valve alignment and contains a 1/4 push-in connection to speed tubing installation. The valves are plated for corrosion resistance, and have a low cracking pressure. They allow free flow from the input port through the output port. Supplying a pilot pressure to the valve allows flow in the opposite direction.
