Priority Demand Valve Category 1

Rapidrop’s innovative electrically driven Priority Demand valve for use with category 1 residential sprinkler systems in accordance with BS 9251: 2021 - Valve for isolating domestic supply in the event of sprinkler activation.
Upon activation of the flow switch or in the event of power loss the valve will automatically close the domestic supply allowing all water to flow to the sprinkler system. The valve will automatically open once the flow switch resets itself or power is restored.
The PDV is pre-wired to the control box (0.5m cable). The control box is powered via a 3pin power supply plug and allows quick installation to the flow switch and alarm device via 2m flying leads.
