Description
Selector valves are used to direct the flow of INERGEN into
a single hazard of a multiple hazard system.
When pneumatic actuation is required for the 1 in. and 2 in.
valves, a Stackable Actuator Assembly, Part No. 428566,
must be ordered separately.
When electric actuation is required for the 1 in. and 2 in.
valves, a Booster Actuator, Part No. 428949, must be
ordered separately.
Selector valves can be manually operated by mounting a
lever actuator either directly onto the valve or onto the top
of the electric actuator. See Lever Release Actuator
Component Sheet for correct actuator.
