Tyco DN25 Spec. Sheet

1" F.NPT inlet x 1" F.NPT outlet.

The 2" (DN50) is designed for either NFPA 13D or NFPA 13R.

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.

The TYCO RAPID RESPONSE Model RSV-1 Residential Shut-Off Valves are intended for use in dual-purpose residential water supply piping that serves both domestic and residential fire protection sprinkler system needs. The 1 Inch (DN25) Valve is intended for NFPA 13D system needs.

When a fi re sprinkler operates, the Model RSV-1 Residential Shut-Off Valve automatically shuts off water fl ow to the domestic system and diverts the available water supply to the fi re sprinkler system. Consequently, when the Model RSV-1 Valve is utilized, the system designer does not need to add the domestic fl ow demand to the fi re sprinkler system fl ow demand, as would otherwise be required by NFPA 13R. Consider use of the Model RSV-1 Residential Shut-Off Valve when either the water supply cannot adequately provide for both the domestic design demand and the fi re sprinkler fl ow demand, or it is necessary to increase the effectiveness of the fi re sprinkler system by automatically shutting off the domestic fl ow.

The Model RSV-1 Residential ShutOff Valve maximizes the effective use of an existing water supply. Therefore, in areas with limited water supplies, it may eliminate the need to add costly pumps, pressurized reservoirs, or electrically operated domestic shut-off valves. The Model RSV-1 Valve has a built-in check valve in the fi re sprinkler system outlet that eliminates the need for a separate check valve. Also, the Model RSV-1 Valve automatically resets, thereby eliminating the need for valve disassembly after a fi re sprinkler.

Approvals: • The 1 Inch (DN25) Model RSV-1 Residential Shut-Off Valve is UL and C-UL Listed. It is suitable for use in water supply arrangements for residential fi re sprinkler systems designed per NFPA 13D. system test or operation.
