High Velocity Water Spray Nozzles are internal swirl plate type open nozzles designed for use in fixed water spray or deluge systems for fire protection. These nozzles produce a solid, uniform, dense core of high velocity water spray to cool surfaces and support fire extinguishment. They are typically used for deluge protection of special hazards such as oil-filled transformers, switch-gear, chemical process equipment, conveyor systems, and flammable liquid storage areas.

Available in brass (HV-AS) or stainless steel (HV-BS) construction, the nozzles feature an inbuilt strainer and can be oriented in any position as needed to cover the hazard. A pressure of 3.5 to 7 bar at the nozzle is recommended for effective high velocity water delivery and rapid extinguishment by emulsification.

Nozzles should be handled with care and stored/shipped in original packing. Use Teflon tape or soft thread sealant on installation. It is recommended the water spray system be inspected regularly and flow-tested at least three times a year, or as required by NFPA/TAC or the local authority having jurisdiction. When ordering, please specify Model, K-Factor, Spray Angle, and Finish.
