  General Description  The Tyco  ®  2 thru 8 inch (DN50 thruDN200) Model PRV-1 Pressure Re-ducing Valves are factory assembledand fully trimmed valve arrangementsfor pressure control. They are used onwater filled pipe where it is necessaryto reduce a higher inlet pressure toa lower delivery pressure under staticand/orresidualflowingconditions.ThePRV-1 is intended to automaticallymaintain the outlet “set pressure”(static and residual) within a closerange, regardless of fluctuations in thehigher pressure inlet line or varyingflow rates.The PRV-1 is provided with a factoryoutlet “set pressure” of 125 psi (8,6bar); however it may be field set to anominal outlet “set pressure” of 80 to225 psi (5,5 to 15,5 bar) per its FMApproval or 80 to 150 psi (5,5 to 10,3bar) per its UL Listing. Typical applications are as follows: ã  Within the main header (Ref. Figure1) supplying wet pipe, dry pipe, del-uge, or preaction system risers,and/or a standpipe system supply-ing hose connections. ã  As part of a sectional floor controlassembly (Ref. Figure 2) supplyingsprinkler systems, and/or hose sta-tions. Features are as follows: ã  Can be installed in any orientation. ã  Eliminates any required bleeding oftrapped air from the diaphragmchamber during installation. ã  Globe or angle pattern. ã  Accurate pressure control. ã  Standard nylon coated internal andexternal.(continued) Model PRV-1 Pressure Reducing Valve 2 thru 8 Inch (DN50 thru DN200), 250 psi (17,2 bar) Pilot Operated, Globe and Angle Body Styles  Technical Services:  Tel: (800) 381-9312 / Fax: (800) 791-5500 Page 1 of 16 TFP1580NOVEMBER, 2007 End Connection2 Inch(DN50)3 Inch(DN80)4 Inch(DN100)6 Inch(DN150)8 Inch(DN200)Nominal Valve SizeThread x ThreadGroove x GrooveGlobeFlange x Flange Available Body Styles, End Connections & Sizes N/A N/AN/AN/AN/AN/AN/AN/AThread x ThreadGroove x GrooveFlange x FlangeAngleBodyStyle= AvailableN/AN/AN/A = Not Available SOUTH AMERICA, CENTRALAMERICA & EASTERN HEMISPHERE End Connection2 Inch(DN50)3 Inch(DN80)4 Inch(DN100)6 Inch(DN150)8 Inch(DN200)Nominal Valve Size Available Body Styles, End Connections & Sizes BodyStyle NORTH AMERICA Thread x ThreadGroove x GrooveGlobeFlange x FlangeN/A N/AN/AN/A= Available N/A = Not AvailableN/AN/AN/AN/A  ã  One piece, one moving part dia-phragm. ã  In-line service. ã  One pilot valve sub-assembly pro-vides for any outlet “set pressure”,i.e., 80 to 225 psi (5,5 to 15,5 bar). WARNING  The Model PRV-1 Pressure Reducing Valves described herein must be in- stalled and maintained in compliance with this document, as well as with the applicable standards of the National Fire ProtectionAssociation,in addition to the standards of any other authori- ties having jurisdiction.  Failure to do so may impair the performance of these devices. The owner is responsible for maintain- ing their fire protection system and de- vices in proper operating condition.The installing contractor or sprinkler manufacturer should be contacted with any questions.Due to the flow regulating charac- teristic of this device, its impact on system hydraulics should be carefully considered, especially when retrofit- ted into existing systems. Downstream pressure adjustment is only to be performed by experi- enced personnel who understand the impact of adjusting the down- stream pressure and who take full responsibility of the readjustment from the factory setting.  The Pilot Valve is provided with a Tamper Cap,which upon removal for purposes of downstream adjustment will provide an indication that the PRV-1 may have been altered from its factory setting.
