Deluge Valves By Des Technico Pvt. Ltd.

We are the most famous manufacturer and supplier of deluge valves in Kolkata, West Bengal, India. "Deluge" Systems are systems in which all open spray nozzles are connected to the water piping system. These are actuated by QB detector system or by electrical signal to solenoid valve. These systems are used for special hazards where rapid fire spread is a concern, as they provide simultaneous application of water over the entire hazard. When there is immediate drop in air & water pressure within the detector line, it releases the pressure against the Diaphragm Unit of the DV causing DV to open & discharge water through all the open water spray nozzles to rapidly control and extinguish the fire. Apart from its wide use in different water lines like HVWS and MVWS system, now a days our DVs are being used along with Foam systems. The DV creates a pressure on Foam Bladder, causing it to squeeze the foam solution out and spray the foam solution through the Foam nozzles.
