Description
Selector valves allow a single agent supply to be utilized for protection of multiple hazards by directing the flow of agent into one specific hazard. This reduces the total amount of agent required to protect multiple hazards. Selector valve systems can only be used to protect one hazard at a time and will not be effective if two or more hazards are involved in a fire simultaneously.
Selector valves are closed during normal operation, blocking the flow of agent through the piping network. A nitrogen actuator with compatible actuator must be installed and connected to each selector valve actuator via a stainless steel pilot line connection. This connection allows the pressure from the nitrogen actuator to be delivered to the selector valve actuator for valve activation. After activation, the selector valve must be manually closed (reset).
