Fire Valves, Fire Valves, Pressure Relief Valves Tyco PRV-1A
Pressure Reducing Valve Pilot Operated ⭐
✅ A line of fire fighting, flow operated pressure reducing valves ⭐
✅ TYCO Model PRV-1A Reducing valve, 2 in to 8 in (DN50 to DN200), factory assembled and arranged Full valve arrangements for pressure control are used on full water pipes where it is necessary to reduce the higher inlet pressure to a lower pressure under static and/or residual flow conditions. The Model PRV-1A Valve is intended to automatically maintain a "set pressure" outlet (static and residual) over a close range, regardless of fluctuations in higher pressure inlet flow or different flow rates. . Valve Model PRV-1A : 125 psi (8.6 bar); however, it may be that the field is set to the nominal output imposing a pressure setting of 90 to 175 psi (6.2 to 12.1 bar).
- UL and C-UL certifications for (2 in. to 6 in) FM approved UL List based on the following factors: • Installation requirements are referenced in the System Sprinkler Installation Standard, NFPA 13 or Standard for Installation of Risers and Valves, NFPA 14, as applicable. • Inspection, testing and maintenance requirements are referenced in Standard for Inspection, Testing and Maintenance of Fire Protection Systems, NFPA 25. • Saved settings of the Model PRV-1A Valve to provide the required outlet pressure and flow for the given application. • Check Valve Model PRV-1A after installation to NFPA 13 and/or NFPA 14 if applicable. • Inspect the Model PRV-1A valve periodically then in accordance with NFPA 25. Note: UL/C-UL approval is based on 3/4 in. use. CLA-VAL Model 55L-60 pressure relief valve. - Maximum inlet pressure 300 psi (20.7 bar) - Factory Outlet pressure setting 125 psi (8.6 bar) - Working pressure 90 to 175 psi (6.2 to 12 bar) = Sizes 2, 3, 6 and 8 in are rated for pressure settings 80 to 175 psi (5.5 to 12 bar) - Pressure loss with inlet pressure Above applied pressure applied Inlet pressure minus outlet. High pressure equals pressure loss. For example, suppose that the inflow pressure is 225 psi (15.5 bar) and the Output Pressure field sets the outlet to 130 psi (9.0 bar), the pressure loss is 95 psi (6, 5 bars). Flow Rating
