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  release  fitting  and  compatible  actuator  must  be  installed in the distribution piping network adjacent to  the  valve.  These  components  allow  the  agent discharge  pressure  from  the  distribution  piping  network to be diverted to the selector valve actuator  through a pneumatic hose  for valve activation. After  activation, the selector valve must be manually closed  (reset).
