3 VS-V SI OU TI IOT K VVS - I-I MOUTI 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 and according to the valve pilot ratio. The valves can be mounted in any position and are protected externally by a zinc plating.
