Pressure valve RSV-1

manualshut-offthreaded

Product Overview
Tyco® Model RSV-1 residential shut-off valves are designed for use in dual-purpose residential water supply piping serving both domestic use and residential fire protection sprinkler systems. When a fire sprinkler operates, the RSV-1 automatically diverts the available water supply to the sprinkler system and automatically resets after operation or testing, eliminating the need to disassemble the valve and maximizing the effective use of an existing water supply, potentially avoiding pumps or pressurized reservoirs.
