The Globe Model RCW valve is a hydraulically operated external resetting differential latching style valve designed for use in double interlock preaction systems where the inadvertent introduction of water into the system piping is highly undesirable. The Model RCW valve is used as an automatic water control valve in double interlock preaction applications, including electric/electric, and electric/pneumatic actuation. The Model RCW valve serves as the primary water control valve installed in the water supply to a double interlock preaction sprinkler system incorporating automatic sprinklers with pressurized air in the system piping.
