Worldwide Contacts www.tyco-fire.com Model PRV-1 Pressure Reducing Valve Pilot Operated, Globe and Angle Body Styles Refer to Technical Data Sheet TFP2300 for warnings pertaining to regulatory and health information. The TYCO Model PRV-1 Pressure Reducing Valves, 2 through 8 in. (DN50 through DN200), are factory-assembled and fully trimmed valve arrangements for pressure control. They are used on water filled pipe where it is necessary to reduce a higher inlet pressure to a lower delivery pressure under static and/or residual flowing conditions. The Model PRV-1 Valve is intended to automatically maintain the outlet "set pressure" (static and residual) within a close range, regardless of fluctuations in the higher pressure inlet line or varying flow rates. The Model PRV-1 Valve is provided with a factory outlet “set pressure” of 125 psi (8,6 bar); however, it may be field set to a nominal outlet “set pressure” of 80 to 225 psi (5,5 to 15,5 bar) per its FM Approval or 80 to 150 psi (5,5 to 10,3 bar) per its UL Listing. Typical applications • Within the main header (Ref. Figure 1) supplying wet pipe, dry pipe, deluge, or preaction system risers, and/or a standpipe system supplying hose connections • As part of a sectional floor control assembly (Ref. Figure 2) supplying sprinkler systems, and/or hose stations • Can be installed in vertical or horizontal orientation • Eliminates any required bleeding of trapped air from the diaphragm chamber during installation • Globe or angle pattern • Accurate pressure control • RILSAN Red coated internal and external • One piece, one moving part diaphragm • In-line service • One pilot valve sub-assembly provides for any outlet “set pressure”, that is, 80 to 225 psi (5,5 to 15,5 bar) The TYCO Model PRV-1 Pressure Reducing Valves described herein must be installed and maintained in compliance with this document and with the applicable standards of the National Fire Protection Association (NFPA), in addition to the standards of any authorities having jurisdiction. Failure to do so may impair the performance of these devices. Owners are responsible for maintaining their fire protection system and devices in proper operating condition. Contact the installing contractor or sprinkler manufacturer with any questions. Due to the flow regulating characteristic of this device, its impact on system hydraulics should be carefully considered, especially when retrofitted into existing systems. Adjustment of the Needle Valve is factory set and must not be altered. • Installation requirements referenced in the Standard for Installation of Sprinkler Systems, NFPA 13, or the Standard for Installation of Standpipe and Hose Valves, NFPA 14, as applicable. • Inspection, testing, and maintenance requirements referenced in the Standard for Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, NFPA 25. • Testing of the Model PRV-1 Valve after installation in accordance with NFPA 13 and/or NFPA 14 as applicable. • Testing the Model PRV-1 Valve tested periodically thereafter in accordance with NFPA 25. Factory Outlet “Set Pressure” Field Outlet “Set Pressure” Range 80 to 225 psi (5,5 to 15,5 bar) per FM Approval, or 80 to 150 psi (5,5 to 10,3 bar) per UL Listing Pressure Loss With Inlet Pressure Above “Set Pressure” The inlet pressure minus the outlet “set pressure” equals pressure loss. For

TFP1580 Page 2 of 16 example, assuming that the inlet flowing pressure is 225 psi (15,5 bar) and the field outlet “set pressure” is 130 psi (9,0 bar), the pressure loss is 95 psi (6,5 bar).

The following items must be considered and applied accordingly for an installation that will be using the Model PRV-1 Pressure Reducing Valve: • The Model PRV-1 Valve may be installed vertically or horizontally and in any orientation without affecting its operating efficiency. When planning the positioning of the Model PRV-1 Valve, it is recommended that consideration be given to the viewing of the pressure gauges. Consideration should also be given to positioning the Model PRV-1 Valve so that the diaphragm cover is facing up. With the cover facing up, internal access is more easily achieved....
