Pressure Restricting Hose Valves Pressure restricting hose valves are used to restrict the pressure of flowing water up to 175 PSI. They are angle hose valves with preset orifices which restrict the volume of water and thereby lower the pressure of the flowing water. NFPA requires restricting valves where the inlet pressure exceeds 100 PSI.

Pressure reducing hose valves and floor control valves are used to control the pressure of flowing water in standpipe and sprinkler systems. NFPA requires pressure reducing valves where the inlet pressure exceeds 175 PSI. The field adjustability of these valves gives

Typical applications include fire sprinkler systems in high-rise buildings, airports, hospitals or any large commercial or residential structure. 90-21 Pressure Reducing Valve 90-42

Designed for use in grid systems or any sprinkler system where pressure relief is required. The Adjustable Pressure Relief Valve can be adjusted from 75-175 psi. (The ¾" option is NOT

Pressure reducing valves (PRV) are frequently used in high rise buildings to keep the pressure on sprinkler systems below the allowable maximum, typically 175 psi, when the supply to the systems can be considerably higher.

Description: Pressure Reducing Valves automatically reduce a higher inlet pressure to a steady lower outlet pressure regardless of changing flow rate and/or varying inlet pressure. The valves pilot control system is very sensitive to slight downstream pressure fluctuations, and will automatically open or close to maintain the desired pressure

The Pressure-Tru® ZW5004 Series Pressure Reducing Valve is listed as a floor control valve, an indicating valve, and a check valve in automatic sprinkler systems. Its also listed as a standpipe valve for CLASS I and CLASS III systems. The valve regulates pressure under both FLOW and NO-FLOW conditions and can be field adjusted with ease thanks to its low torque design.

The Zurn Wilkins Model ZW209FP Pilot Operated Pressure Reducing Valve is designed specifically for Fire Suppression Systems to reduce high inlet pressures to a safe and stable outlet pressure. The pilot assembly reacts to changes in downstream pressure allowing the main valve to modulate between the closed and open position ensuring

ressures in fire-protection systems that exceed the maximum allowed by NFPA standards must be reduced to acceptable levels for sprinkler systems and fire department hose valves. High-rise buildings, for exam-ple, often require pressure-reducing valves. A pump that is capable of supplying the minimum acceptable pressure to

Our pilot operated pressure reducing valves are designed specifically for Fire Suppression Systems to reduce high inlet pressures to a safe and stable outlet pressure. The pilot assembly reacts to changes in downstream pressure allowing the main valve to modulate between the closed and open position insuring a constant downstream set pressure. Once the downstream
