General   DescriptionThe TYCO Type HV Nozzles are open (non-automatic) directional spray nozzles with individual inlet strainers. They are designed for use in water spray fixed systems for fire protection applications where a high velocity water application may be required, such as for the protection of flammable liquids.Â
The Type HV Nozzles feature an integral strainer for use when the authority having jurisdiction (other than NFPA applications) requires the use of individual strainers in addition to main pipeline strainers for nozzles having an orifice diameter of 3/16 inch (4,8 mm) or less.Â
Available in brass or stainless steel, the six patterns of the Type HV Nozzles provide a wide variety of orifice sizes and distribution characteristics. As water passes through the internal swirl plate, a swirling action is produced, prior to the water being discharged through the orifice tip of the body, resulting in a solid conical spray pattern of water droplets being discharged over a defined area.Â
High velocity type nozzles are principally used in water spray systems for the protection of fixed hazards such as transformers, circuit breakers, diesel engines and diesel storage tanks, turbo alternators, lube oil systems, oil fire boilers, and similar hazards. They are capable of rapidly extinguishing oil fires by emulsification, cooling, and smothering. The surface cooling effects of high velocity type nozzles also minimizes the possibility of reignition after a fire extinguishment.Â
It is recommended that the end user be consulted with respect to the suitability of the materials of construction for any given corrosive environment. Effects of ambient temperature, concentration of chemicals, and gas/chemical velocity should be considered, at a minimum, along with the corrosive nature to which the nozzles may be exposed.
 The TYCO Type HV Nozzles are a redesignation for the Gem Type HV.
