Description

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. Use hose P/N: 01-3273-1200 and adapter P/N: 85-025125- 000 to connect a nitrogen pilot cylinder to the pressure regulator on the back-plate manifold to provide operating pressure for the 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.
