Products Description
When a flow of water from the system equals or exceeds that of a single sprinkler, the valve is to actuate a fire alarm.
The wet fire alarm check valve is designed to allow water to flow into the fire sprinkler system when a pressure drop is detected. It contains a check valve mechanism that opens and allows water to enter the system when the in the fire sprinkler system drops below a certain set point. This typically occurs when a fire occurs and activates the sprinkler heads.
Its core functions are twofold:
Under normal conditions, it allows water to flow into the system network in one direction and prevents water from flowing back; In case of fire, it not only allows water to flow towards the sprinkler heads to extinguish the fire, but also automatically activates the hydraulic alarm bell and pressure switch to issue audible and visual alarms.
Features
• The fire extinguishing response is extremely fast
• Simple and reliable structure
• 100% effective alarm
• The daily maintenance of the system is simple and convenient
• Low investment cost and economic efficiency
