2-5 SELECTOR VALVES
Selector valves are used to distribute agent where multiple spaces are protected from the same
or multiple banks of cylinders.
All Kidde IGS Systems selector valves are 2-way ball valves with full bore. They operate
pneumatically, using pressure tapped from the manifold and routed through a pressure
regulator on the backplate manifold. This pressure passes through the associated solenoid on
the backplate manifold which is opened via the control panel, allowing agent pressure to flow
to the required selector valve.
Selector valves have threaded inlet and outlet ports for connection to the distribution piping
for sizes 1”, 1 1/2”, and 2”. For 3” and 4” selector valves, use flanges to connect to the system
piping. To enable connection of actuation hose to selector valve the following adapters are re-
quired; for DN 25mm to DN 50mm use part# 15-8662-0042 and for DN80mm to DN 100mm
use part# 15-8662-0041.

CAUTION
Selector valves do NOT prevent flow in the direction opposite the arrow.
