Pilot Operated
Check Valves
Designed for use in applications
requiring an actuator 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 or 1/8 NPT
output port which mounts directly
on a cylinder, minimizing space
requirements and easing 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 pilot ports are available
to fit plumbing specifications.
