Alarm Systems

wet

wet alarm valve

 The wet alarm valve is a key component of the wet automatic sprinkler system. The pipe network of the system is filled with pressurized water and is in standby working state for a long time. When a fire occurs somewhere in the protected area, the ambient temperature rises and the thermal sensitive element of the nozzle ruptures.
