Model RSV-1 Residential Domestic Shutoff Valve
1 Inch (DN25)
For Dual Purpose Residential Water Supply
General
Description
TM
The Rapid Response
, Model RSV-1
Residential Domestic Shutoff Valves
are intended for use in dual-purpose
residential water supply piping that
serves both domestic and NFPA 13D
residential fire protection sprinkler
system needs.
When a fire sprinkler operates, the
RSV-1 Valve will automatically shut off
water flow to the domestic system and
divert the available water supply to the
fire sprinkler system. Consequently,
when the RSV-1 is utilized, the system
designer need not add the domestic
flow demand to the fire sprinkler sys-
tem flow demand.
Use of the Model RSV-1 Residential
Domestic Shutoff Valve should be con-
sidered when either the water supply
cannot adequately provide for both the
domestic design demand and fire
sprinkler flow demand, or it is desir-
able to increase the effectiveness of
the fire sprinkler system by automat-
ically shutting off domestic flow.
The RSV-1 maximizes the effective
use of an existing water supply and,
therefore, in areas with limited water
supplies, it may eliminate the need to
add costly pumps, pressurized reser-
voirs, or electrically operated domestic
shutoff valves. The RSV-1 has a built-
in check valve in the fire sprinkler sys-
tem outlet that eliminates the need for
a separate check valve.
RSV-1 automatically resets, thereby
eliminating the need for valve disas-
sembly after a fire sprinkler system
test or operation.
The Model RSV-1 Residential Domes-
tic Shutoff Valve is a redesignation of
the Gem Model F540 and Star Model
S370 Residential Domestic Shutoff
Valves.
