Priority Demand Valve
AQUATECH PRESSMAIN Fire Priority Valve PDV systems feature a motorised valve and control panel. They are designed for domestic sprinkler systems in compliance with BS9251:2021. When the system detects activation, it closes the valve, diverting water to the sprinklers.
The Enhanced PDV-E variant keeps the valve closed until manually reset, usually after the fire brigade relinquishes control of the building. This system optimises water supply for efficient fire suppression in domestic settings.
