High Velocity Water Spray Nozzle
These nozzles are designed to be installed in groups or zones of protection and operate simultaneously to rapidly extinguish high intensity oil fires. The type of nozzle, the flow rate, and discharge angle is determined by the type of risk involved.
These groups of nozzles are linked to a detection airline and a Deluge system control valve. In the event of a fire, the devices in the detection airline operate to release air within the system. This in turn operates the Deluge system control valve, which opens to discharge water simultaneously through all the open nozzles within the protected area.
High Velocity Water Spray Nozzles are internal swirl plate type open nozzles designed for use in fixed water spray or deluge system for the fire protection application.

Medium Velocity Water Spray Nozzle
Medium velocity water spray nozzle has an external deflector, which discharges water in a directional cone shaped pattern of small droplet size. The water is uniformly distributed over the surface to be protected.
The nozzle is used in deluge water spray system for special hazard fire protection application.
As the design and intent of specific water spray system may vary considerably, a MV nozzle is made available in several combinations of orifice sizes and spray angles.
