Fire Priority Demand Valve for Domestic Fire Sprinkler Systems

Ideally suited for any brand of domestic sprinkler systems that use the water booster pressure set for the domestic water supply and fire suppression.

Fire Priority Demand Valve


If the sprinkler system is activated, it will send a signal to the Fire Priority Demand Valve which will close, isolating the flow of water to the domestic riser enabling the booster set to pump all the available water to the sprinkler riser.

The valve is held closed until manually reset (e.g. once the fire brigade has handed the building back to the owner.)
