Double-piston actuator SRC and ARC valves

Double Piston actuator
For the SRC and ARC valves a double-piston actuator is available. With this actuator a stop valve NC can be converted into a two-step valve (metering valve) and a change over valve, NC or NO, into a three-position valve. For operating the valves a second connection for compressed air is required.
Two-step valve
In the two-step valve the valve plug can take up three positions, fully open, throttled and closed. The throttled position can be adjusted by means of spacers in the actuator.
