SINGLE AND DOUBLE ACTING PILOT CHECK VALVES - IN-LINE MOUNTING
With the acting pilot check valves, a single or double acting actuator can be
locked in any position.
Sealing is guaranteed by tempered, ground, tapered steel poppets, releasing
is by venting the piloted openings “A” and “B” according to the valve pilot
ratio. The valves can be mounted in any position and are protected externally
by a zinc plating.
