GeneralDescriptionThe Type HV Nozzles are open (non-automatic) directional spray nozzleswith individual inlet strainers. They aredesigned for use in water spray fixedsystems for fire protection applicationswhere a high velocity water applicationmay be required, such as for the pro-tection of flammable liquids.

The Type HV Nozzles feature an inte-gral strainer for use when the AuthorityHaving Jurisdiction (other than NFPAapplications) requires the use of indi-vidual strainers in addition to mainpipeline strainers for nozzles havingan orifice diameter of 3/8 inch (9,5 mm)or less.

Available in brass or stainless steel,the six patterns of the Type HV Noz-zles provide a wide variety of orificesizes and distribution characteristics.As water passes through the internalswirl plate, a swirling action is pro-duced, prior to the water being dis-charged through the orifice tip of thebody, resulting in a solid conical spraypattern of water droplets being dis-charged over a defined area.

High velocity type nozzles are princi-pally used in water spray systems forthe protection of fixed hazards such as

transformers, circuit breakers, dieselengines and diesel storage tanks,turbo alternators, lube oil systems, oilfire boilers, and similar hazards. Theyare capable of rapidly extinguishing oilfires by emulsification, cooling, andsmothering. The surface cooling ef-fects of high velocity type nozzles alsominimizes the possibility of reignitionafter a fire extinguishment.

It is recommended that the end user beconsulted with respect to the suitabilityof the materials of construction for anygiven corrosive environment. The ef-fects of ambient temperature, concen-tration of chemicals, and gas/chemicalvelocity, should be considered, at aminimum, along with the corrosive na-ture to which the nozzles may be ex-posed.

The Type HV Nozzles are a redesigna-tion for the Gem Type HV.

WARNINGSThe Type HV Nozzles describedherein must be installed and main-tained in compliance with this docu-ment, as well as with the applicablestandards of the National Fire Protec-tion Association, in addition to thestandards of any other authorities hav-ing jurisdiction. Failure to do so mayimpair the performance of these de-vices.

The design of individual water sprayfixed systems can vary considerably,depending on the characteristics andnature of the hazard, the basic pur-pose of the spraying system, the con-figuration of the hazard, and wind/draftconditions. Because of these vari-ations as well as the wide range ofavailable nozzle spray characteristics,the design of water spray fixed sys-tems for fire protection must only beperformed by experienced designerswho thoroughly understand the limita-tions as well as capabilities of suchsystems.

The owner is responsible for maintain-ing their fire protection system and de-

vices in proper operating condition.The installing contractor or sprinklermanufacturer should be contactedwith any questions.

DesignCriteriaNozzle Placement. The nominal over-all spray patterns, spacing, and maxi-mum recommended axial distancesfor six patterns of the Type HV Nozzlesare given in Figure 2 for residual (flow-ing) pressures of 30 to 80 psi (2,1 to5,5 bar). A minimum residual pressureof 30 psi (2,1 bar) can typically be usedfor most applications; however, a mini-mum residual pressure of 50 psi (3,4bar) is recommended for applicationsrequiring higher velocity water deliv-ery, such as those specifying rapid ex-tinguishment of oil fires by emulsifica-tion.

With reference to Figure 2, use of the“Design Spray Profile” for the “DesignSpray Area” will help assure that directimpingement on all surfaces will occur.The “Design Spray Area” shown at thetop Figure 2 - Part 2 of 2 on Page 4consists of the square of length “S”within the circular “Overall SprayArea”.

The maximum recommended axialdistances given in Figure 2 are basedon maintaining the specified spray pat-terns under a maximum wind conditionof 15 MPH (24 km/h).

Figure 3 provided a reference guideshowing the overall still air spray pat-terns beyond the maximum 15 MPH(24 km/h) axial distances, when pro-

jecting horizontally. As shown in Fig-ure 3, the spray patterns become non-concentric, beyond a certain point, dueto the affects of gravity.

Main Pipeline Strainers. Eventhough individual strainers have beenprovided, main pipeline strainers arerequired for systems utilizing Type HVNozzles, since their waterways areless than 3/8 inch (9,5 mm) diameter.

InstallationType HV Nozzles must be installed inaccordance with the following instruc-tions:

NOTEA leak tight 1 inch NPT nozzle jointshould be obtained with a torque of 20to 30 ft.lbs. (26,8 to 40,2 Nm). A leaktight 1-1/4 inch NPT nozzle jointshould be obtained with a torque of 30to 40 ft.lbs. (40,2 to 53,6 Nm). Higherlevels of torque may distort the nozzleinlet and cause impairment of the noz-zle.

Step 1. With pipe thread sealant ap-plied to the pipe threads, hand tightenthe nozzle into the nozzle fitting.

Step 2. Tighten the nozzle into thenozzle fitting using an adjustable cres-cent wrench. With reference to Figure1 the adjustable crescent wrench is tobe applied to the wrench hex.

Care andMaintenanceThe Type HV Nozzles must be main-tained and serviced in accordancewith the following instructions:

NOTEBefore closing a fire protection systemmain control valve for maintenancework on the fire protection system thatit controls, permission to shut down theaffected fire protection system must beobtained from the proper authoritiesand all personnel who may be affectedby this action must be notified.Type HV Nozzles must never bepainted, plated, coated or altered inany way after leaving the factory; oth-erwise, the spray performance may beimpaired.

Care must be exercised to avoid dam-age to the nozzles - before, during, andafter installation. Nozzles damaged bydropping, striking, wrench twist/slip-page, or the like, must be replaced.

Frequent visual inspections are rec-ommended to be initially performed fornozzles installed in potentially corro-sive atmospheres to verify the integrityof the materials of construction as theymay be affected by the corrosive con-ditions present for a given installation.Thereafter, annual inspections perNFPA 25 are required.

Water spray fixed systems for fire pro-tection service require regularlyscheduled care and maintenance bytrained personnel. In addition to in-specting nozzles for proper spray per-formance during water flow trip tests ofthe system, it is recommended thatnozzles be periodically inspected forbroken or missing parts or evidence ofimpaired protection. The inspectionsshould be scheduled weekly or as fre-quently as may be necessary, and cor-rective action must be taken to ensurethat the nozzles will perform as in-tended in the event of a fire.

The owner is responsible for the in-spection, testing, and maintenance oftheir fire protection system and de-vices in compliance with this docu-ment, as well as with the applicablestandards of the National Fire Protec-tion Association (e.g., NFPA 25), inaddition to the standards of any otherauthorities having jurisdiction. The in-stalling contractor or sprinkler manu-facturer should be contacted relativeto any questions.

It is recommended that water sprayfixed systems be inspected, tested,and maintained by a qualified Inspec-tion Service in accordance with localrequirements and/or national codes.

LimitedWarrantyProducts manufactured by Tyco Fire &Building Products (TFBP) are war-ranted solely to the original Buyer forten (10) years against defects in mate-rial and workmanship when paid forand properly installed and maintainedunder normal use and service.
