2 NOTICEThe TYCO Model PRV-1 Pressure Reducing Valves described herein must be installed and maintained in compli-ance with this document and with the applicable standards of the National Fire Protection Association, in addi-tion to the standards of any authorities having jurisdiction. Failure to do so may impair the performance of these are responsible for maintaining their fire protection system and devices in proper operating condition. Contact the installing contractor or sprinkler manufacturer with any to the flow regulating characteris-tic of this device, its impact on system hydraulics should be carefully consid-ered, especially when retrofitted into existing of the Needle Valve is factory set and must not be DescriptionThe TYCO Model PRV-1 Pressure Reducing Valves, 2 through 8 Inch (DN50 through DN200), are factory-assembled and fully trimmed Valve arrangements for Pressure control.

3 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 main-tain the outlet set Pressure (static and residual) within a close range, regard-less of fluctuations in the higher pres-sure inlet line or varying flow 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 2 of 16 Technical DataApprovalsUL and C-UL ListedFM ApprovedThe UL Listing is based on: 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.

9 The Body is RILSAN polyamide 11 coated, ductile iron per ASTM A 536-77, Grade 65-45-12. The Diaphragm Cover is RILSAN polyamide 11 coated, ductile iron per ASTM A 536-77, Grade 65-45-12. The Diaphragm is nylon fabric-rein-forced, natural rubber per ASTM D2000. Diaphragm Cover Fasteners are galvanized carbon steel. The Pilot Valve is brass and stain-less steel with nylon fabric-rein-forced, natural rubber per ASTM D 2000 diaphragm. The Strainer is brass and stainless steel. Pressure Gauges have a 2-1/2 inch (65 mm) diameter, stainless steel case, and 0 to 350 psi (25 bar) pres-sure rating. Tube, Fittings, and Needle Valve are copper, brass, and stainless reference to Figure 4, the system water supply Pressure from the inlet cavity of the Model PRV-1 Valve enters the Diaphragm Chamber through a Strainer and Needle Valve .

10 The factory set Needle Valve provides the required orifice size for the supply line to the Diaphragm Chamber to optimize flow from the Diaphragm Chamber through the Pilot Valve is controlled by a regulating spring that is factory set, and subsequently field adjustable, to the desired downstream set Pressure that is to be maintained. A sensing line connects the outlet of the Pilot Valve to the system piping downstream of the Model PRV-1 Valve via the Pressure Sensor Insert in the outlet the downstream Pressure rises above the set Pressure of the spring, exit flow from the Diaphragm Chamber through the Pilot Valve to the Model PRV-1 Valve outlet cavity is stopped and Pressure increases in the Diaphragm Chamber.
