Water Spray Nozzle

 Medium Velocity Reverse Action Water Spray Nozzle is an open orifice, directional spray nozzle, designed for use in water spray fixed systems for fire protection applications. Reverse Action nozzle comes in various materials of construction and is UL Listed. The nozzle has an external deflector that discharges a uniformly filled cone of medium velocity water droplets in upright/reverse direction.

 Water Curtain Nozzles are non-automatic open, outside sprinklers intended for the protection of windows, walls, steel beams, columns, roofs and any other structures against exposure fire and heat penetration. Water Curtain nozzles are generally installed with orifice slot pointing downwards direction. The curtain spray absorbs and reflects heat radiation, minimizing the amount of heat reaching the structure/area to be protected.
