What is the PRESSURE REDUCING VALVE？

A pressure reducing valve (PRV), also known as a pressure regulating valve or pressure control valve, is a valve used in a fluid system to reduce and regulate the pressure of the fluid passing through it. Pressure reducing valves play a critical role in maintaining system stability, protecting downstream equipment, and ensuring efficient operation by providing precise pressure regulation in fluid systems.

key features of PRESSURE REDUCING VALVE:

1. Pressure Regulation: The primary function of a pressure reducing valve is to reduce the pressure of the fluid flowing through it to a predetermined level regardless of fluctuations in upstream pressure or flow. This ensures a consistent and controlled pressure supply to downstream equipment or systems.

2. Automatic operation: The pressure reducing valve operates automatically, responding to changes in upstream pressure to maintain constant downstream pressure. When the upstream pressure exceeds the set point, the valve opens to allow fluid to pass through, reducing the pressure to the desired level. Conversely, when the upstream pressure drops below the set point, the valve closes to restrict flow and maintain the desired downstream pressure.

3. Adjustable set point: Many pressure reducing valves are equipped with an adjustable set point, allowing the operator to manually adjust the desired downstream pressure within a certain range. This flexibility allows for customization to meet specific system requirements or operating conditions.

4. Pilot control mechanism: Pressure reducing valves often include a pilot control mechanism that senses downstream pressure and adjusts the valve position accordingly to achieve the desired set point. Depending on the application and requirements, this pilot control can be pneumatic, hydraulic or electronic.

5. Pressure relief function: In addition to pressure relief, some pressure reducing valves are also equipped with a pressure relief function to prevent overpressure. If downstream pressure exceeds a certain threshold, the valve will open fully to relieve excess pressure and prevent damage to downstream components.

6. Versatility: Pressure reducing valves are used in a wide variety of industries, including water distribution systems, HVAC systems, pneumatic systems, irrigation systems and process industries. They are available in different sizes, configurations and pressure ratings to accommodate different fluid types and operating conditions.
