During the design of a residential sprinkler system, domestic water use should be taken into consideration unless the domestic supply can be stopped when a sprinkler operates.

When a sprinkler operates, water supply is automatically diverted from the domestic system to the sprinkler system.

Eliminates the need for pumps, pressurized storage tanks, or electrically operated domestic shutoff valves.

Valve automatically resets after the fire protection system is returned to normal service.

Maximum rated working pressure is 175 psi (12,1 bar).

Listings and Approvals: UL, C-UL, & NSF.

2 Inch (DN50) Valve:

In order for the 2 Inch (DN50) Model RSV-1 Valve to operate automatically at sprinkler activation, the fi re sprinkler system from the water supply main to the most hydraulically remote sprinkler must be designed to provide a minimum single sprinkler fl ow of 8 GPM (30,5 LPM) when the water supply pressure at the water supply main is at its minimum expected value. The minimum single sprinkler fl ow rate of 8 GPM (30,5 LPM), required for use with the 2 Inch (DN50) Model RSV-1 Valve, does not take precedence over any more hydraulically demanding single sprinkler flow rate specified for the residential sprinklers in use.
