Pilot Operated Check Valves


Designed for use in applications requiring an acutator to be locked in position, Pilot Operated Check Valves allow free flow from the input port through the output port. Supplying a pilot pressure to the valve allows flow in the opposite direction.

Pneumadyne's new Pilot Operated Check Valves are ideal for reliably holding an actuator position in a variety of applications.  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.  10-32 (F) and 1/4 push-in ports are available to fit plumbing specifications.
