Priority Demand Valve
Fig. PDV-02V2
Product Description
Rapidrop's innovative electrically driven Priority Demand valve
for use with mains water supply or stored water supply residential
sprinkler systems.
Designed to meet BS 9251: 2021 - Valve for isolating domestic
supply in the event of sprinkler activation.
Upon activation of a flow switch/alarm relay, the valve will
automatically close the domestic supply allowing all water to flow
to the sprinkler system and remain closed until manually reset.
Upon activation of a low level tank switch (if installed) the valve will
automatically close and re-open once the low level tank switch
resets itself.
The priority demand valve is available in ball or butterfly type
body(depending on connection) attached to a specific actuator
(dependant on size) The appropriate PDV control box will need to
be ordered separately.
The priority demand valve is available in two different configurations:
- Single PDV - Used in systems designed with a single priority
demand valve.
- Multiple PDV - Used in systems designed with multiple priority
demand valves. Up to 25 PDVs can be simultaneously activated
through a single flow switch/ alarm relay.
