Difference of Pressure Reducing Valves and Pressure Relief valves - Mt.H

The pressure reducing valves are completely automatic. 2. A Pressure Reducing Valve is a relief valve and controls and maintains a preset, reduced downstream (outlet) pressure by causing the main valve to throttle and sustain the desired reduced pressure regardless of variations in demand and upstream (inlet) water pressure. Pressure Relief Valves

Difference between Pressure Relief Valve and Pressure Safety Valve

The relief valve is designed or set to open at a defined pressure so that if the excess pressure is getting buildup in the process vessel/equipment (Such as : boiler, pressure vessel, pressure cooker etc) then the relief valve is forced to open just by lifting of the lever and a portion of the fluid is diverted through the auxiliary route.

Pressure relief valves & pressure regulators - What's the difference

A pressure reducing valve is a device that varies cross-section (throttles a valve) to maintain a set-point pressure at it's outlet (or another point of interest). Ideally, this works over a range of flow conditions. A relief valve 'cracks' at a set-point-pressure, typically to prevent system pressures from exceeding some value.
