Pilot Operated Pressure Reducing Valve (PRV)

ALIS Valves offers Pilot Operated Pressure Reducing Valves (PRVs) for industrial applications requiring accurate downstream pressure regulation and stable flow control. These valves use a pilot control mechanism to regulate the operation of the main valve according to the required outlet pressure. The pilot senses downstream pressure and adjusts the control signal, allowing the main valve to respond to changes in system demand. This arrangement can provide precise pressure regulation and higher flow capacity compared with some direct-acting designs, depending on the valve configuration and operating conditions.

Pilot Operated Pressure Reducing Valves are suitable for water distribution networks, industrial processing facilities, steam systems, commercial buildings and other applications requiring controlled pressure reduction. They help maintain the desired downstream pressure while managing variations in inlet pressure and flow demand. Important selection factors include inlet pressure, required outlet pressure, flow capacity, operating temperature, process media, valve size, pilot configuration, body material and connection type. Selecting the appropriate PRV according to system requirements helps support stable pressure control, efficient operation and reliable performance under specified working conditions.
