The Series RSV Pilot Solenoid Valve is used to operate the Series RDCV remote type diaphragm valve. Series RDCV does not include an integral solenoid and needs to be activated remotely. The RSV can drive all size diaphragm valves. The units can be bought separately for mounting in a panel or can be purchased mounted on our SVE enclosure. Consult factory for mounting of RSV valves with our DCT timer boards together in one enclosure all pre-wired.
