COMPONENT DESCRIPTION

2.1

2-Way NPT and Grooved Selector Valves

P/N: See Table 2
Selector valves are used to distribute agent where multiple hazards are protected from the
same or multiple banks of cylinders. These selector valves are 2-way ball valves with full bore,
available in sizes to match 1, 1 1/2, 2, 3, and 4 inch pipes.
The valves operate pneumatically, using pressure from either a Nitrogen pilot cylinder or, in
the case of inert systems, from the agent manifold. The pressure passes through a pressure
regulator, then through the associated solenoid which is opened via the control panel, allowing
the pressure to flow to the required selector valve.
For selector valves with NEMA 4 rated solenoids, Kidde Fire Systems offers back-plate
manifolds which includes the various number of solenoids to ease installation. For more
information, see Section 2.1.1, Back Plate Manifold with Solenoids for Selector Valves.
Selector valves with NEMA 7 rated solenoids cannot use the back-plate manifolds as, the
solenoids are mounted directly on the selector valve.
Selector valve sizes 1, 1 1/2, and 2 in. have NPT threaded inlet and outlet ports for connection
to the distribution piping. Selector valve sizes 3 and 4 in. use grooved fitting to connect to the
system piping. When installing, choose the correct mating fittings to match with the groove
fitting of the selector valves.
