Steam Pressure Reducing Valve (PRV)

ALIS Valves offers Steam Pressure Reducing Valves (PRVs) for industrial applications requiring reliable steam pressure regulation and stable downstream operating conditions. These valves are designed to reduce higher inlet steam pressure to a predetermined lower outlet pressure and regulate the flow of steam according to system demand. By maintaining suitable downstream pressure, they help protect steam pipelines, heat exchangers, boilers and connected process equipment from excessive pressure. Depending on the design, the valve may use a spring-loaded, diaphragm-operated or pilot-operated mechanism to provide the required pressure control.

Steam Pressure Reducing Valves are suitable for applications in power generation plants, pharmaceutical facilities, food processing units, chemical industries, refineries and industrial steam distribution systems. They are commonly used in heating systems, process equipment and steam networks where controlled pressure is essential for safe and efficient operation. Important selection factors include inlet and outlet pressure, steam flow rate, operating temperature, pressure drop, valve size, body and trim materials, connection type and control requirements. Selecting the appropriate PRV according to system specifications helps support stable steam pressure, efficient energy use and reliable performance under the intended operating conditions.
