General Description The TYCO Model RV-1 Pressure Relief Valves, 2 through 8 inch (DN50 through DN200), are factory ssembled and fully trimmed valve arrangements for relief of excess water pressure. These valves are typically used to automatically relieve excess pressure in a fre protec-tion system that utilizes a fire pump. Pilot-controlled, the Model RV-1 Valve maintains a relatively constant system pressure at the pump discharge as fow demands change. The Model RV-1 Pressure Relief Valve may be feld-set to a nominal relief “set pressure” of 30 to 250 psi (2,1 to 17,2 bar).

Features are as follows: 

• Globe or angle pattern 

• Installation in any orientation 

• One-piece, one-moving-part diaphragm 

• Ceramic enamel-coated interior 

• Standard nylon-coated exterior 

• Accurate pressure control 

• In-line service 

• No need to bleed trapped air from the diaphragm chamber 

• One pilot valve sub-assembly that provides for any outlet “set pressure”; that is; 30 to 250 psi (2,1 to 17,2 bar) Technical Data Approvals UL Listed; FM Approved Maximum Inlet Pressure 250 psi (17,2 bar) Temperature Range 50°F to 175°F (10°C to 80°C) Field Relief “Set Pressure” Range 30 to 250 psi (2,1 to 17,2 bar) NFPA 20 Recommended Maximum Flow • 2 Inch (DN50): 250 GPM (946 LPM) 

• 3 Inch (DN80): 500 GPM (1893 LPM) 

• 4 Inch (DN100): 1000 GPM (3785 LPM) 

• 6 Inch (DN150): 2500 GPM (9462 LPM) 

• 8 Inch (DN200): 5000 GPM (18925 LPM) Refer also to Figure 4 for inlet pres-sure versus fow characteristics.
