Tyco® Model RSV-1 residential shut-off valves are designed to be used in dual-purpose residential water supply piping that serves both domestic and residential fire protection sprinkler system needs. When your fire sprinkler operates, the Model RSV-1 residential shut-off valve automatically diverts the available water supply to the fire sprinkler system. This valve maximizes the effective use of an existing water supply — and in areas with limited water supplies, it may eliminate the need to add costly pumps, pressurized reservoirs, or electrically operated domestic shut-off valves. Also, the Model RSV-1 valve automatically resets, so you don’t need to disassemble the valve after a fire sprinkler system test or operation.
