THE 2" MODEL RSV-1 RESIDENTIAL SHUT-OFF VALVE is designed for use in dual-purpose residential water supply systems. After sprinkler activation the valve automatically shuts off water flow to the domestic system and diverts it to the sprinkler system. It eliminates the need for costly pumps, pressurized reservoirs or electrically operated domestic shut-off valves. It features a built-in check valve. It also automatically resets, eliminating the need for valve disassembly after a sprinkler system test.
