Pressure Reducing Valve

A Pressure Reducing Valve (PRV) is a critical control device installed in process pipelines of boilers and heaters to regulate and maintain downstream steam or fluid pressure at a safe and constant level, regardless of fluctuations in upstream supply pressure. It ensures stable pressure conditions for process equipment, protecting pipelines, heat exchangers, burners, and other downstream components from overpressure, ensuring operational efficiency and safety. In boiler and heater applications, the PRV is specifically designed to handle high-pressure saturated or superheated steam, hot water, or thermal fluids , reducing them to the required set pressure suitable for various process requirements. The valve operates automatically using a spring-loaded or pilot-operated mechanism that balances inlet pressure, downstream demand, and set point adjustment, thereby maintaining consistent output. By providing controlled pressure, PRVs contribute to energy efficiency, equipment longevity, and safe operation of thermal systems. They also reduce the risk of thermal stress and leakage in pipelines and prevent potential failures caused by overpressure conditions.
