A Pressure Relief Valve is defined by NFPA 20 (3.3.67.5 Relief Valve) as "A device that allows the diversion of liquid to limit excess pressure in a system." In general, a PRV is a safety device, designed to protect a pressurized system during an overpressured event.

Nov 19,  · The challenge is to reduce the pressure for safe use by firefighters. BERMAD met the challenge by dividing the tunnels into water pressure zones using BERMAD hydraulic pressure reducing valves. Two parallel pipe lines laid alongside the rails to supply water to hoses and sprinklers in the tunnels are connected and controlled by an array of

The challenge is to reduce the pressure for safe use by firefighters. BERMAD met the challenge by dividing the tunnels into water pressure zones using BERMAD hydraulic pressure reducing valves. Two parallel pipe lines laid alongside the rails to supply water to hoses and sprinklers in the tunnels are connected and controlled by an array of

910GF. Fire System Pressure Reducing Valve. Series 910GF (Globe) Pressure Reducing Valve meets all requirements for UL Listed fire protection service. Automatically reduces a higher inlet pressure to an adjustable lower outlet pressure regardless of

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

Fire System Pressure Reducing Valve. Series 910AF (Angle) Pressure Reducing Valve meets all requirements for UL Listed fire protection service. Automatically reduces a higher inlet pressure to an adjustable lower outlet pressure regardless of changing flow rate or varying inlet pressure.

Dec 06,  · The pressure reducing valve (PRV) is designed to reduce both residual (flowing) and static (non-flowing) water pressure. In contrast, pressure restricting devices (PRDs) are designed to only control residual (flowing) water pressure. This differentiation is vital to understanding the design application and expectations of the system.
