A Pressure Regulating Valve (PRV) is a type of control valve used to maintain a predetermined downstream pressure, regardless of fluctuations in upstream pressure or flow conditions. These valves are essential in various industries, including water supply systems, gas distribution networks, and industrial process control, to ensure stable and safe operation of equipment and systems.
Understanding and choosing the right pressure regulating valve for a specific application involves considering factors like flow rate, pressure range, fluid type, and environmental conditions. Proper selection and maintenance of PRVs are critical to the safe and efficient operation of many systems.
Safety: Prevents equipment damage and ensures safe operation by maintaining pressure within safe limits.
Efficiency: Enhances system performance by providing stable pressure, reducing energy consumption.
Reliability: Reduces wear and tear on components by avoiding pressure fluctuations.
In the case of a pressure reducing valve, the outlet pressure (pressure prevailing on the outlet side) is set. The set pressure of a pressure reducing valve always refers to the outlet pressure at zero usage. i.e. no medium is flowing through the valve and all draw-off points are closed.
If a draw-off point on the outlet side is opened medium flows through the valve and the outlet pressure falls below the set pressure. Once the draw-off point is re-closed the outlet pressure rises again to the set pressure.
