Wet alarm check valve for alarm valve fire sprinkler system
Preaction Alarm Valve Device
ZSFY type pre-action device gets the fire automatic detection and alarm technology and automatic sprinkler system together.To protect the object to play a dual role in protection,In the absence of fire when the system side of the pipeline inflatable, so the system has a dry system characteristics, to meet the high temperature and cold conditions under the conditions of automatic sprinkler fire.Fire alarm and fire alarm controller to open the deluge valve, into a wet system, both dry and wet system advantages.

Wet Alarm Valve Device
Alarm Valve is a double seated clapper check valve with grooved seat design, which ensures positive water flow for alarm operation and is designed for installation in wet pipe sprinkler system. External bypass prevents false alarm under all supply pressure condition. In the event of variable pressure condition, false alarm is prevented with the provision of retard chamber, thus the design allows for installation under both variable and constant supply pressure condition.
Operation of one or more automatic fire sprinklers causes the water to flow into the sprinkler system causing the alarm valve to open, allowing continuous flow of water into the system and transmittal of alarm, both electrical and mechanical.
