The Adjustable Pressure Reducing Valve (PRV) is a self-operated control valve designed to automatically reduce high inlet pressure to a safe and stable outlet pressure. With an adjustable pressure setting, it ensures consistent downstream pressure, protects pipelines and equipment, and improves system efficiency. It is widely used in water supply systems, steam lines, compressed air networks, chemical plants, fire protection systems, and industrial process applications.

Product Specifications and Overview

ALIS Valves offers Adjustable Pressure Reducing Valves designed to reduce higher inlet pressure to a lower, controlled downstream pressure in industrial piping and fluid handling systems. These valves help maintain a more stable outlet pressure despite variations in upstream pressure or flow demand, depending on the valve design and operating conditions. An adjustable setting mechanism, such as a spring-loaded screw or adjustment knob, allows the required downstream pressure to be set within the valve’s specified operating range. Depending on the application, the valve may use a direct-acting or pilot-operated design, with suitable body materials, diaphragm or piston assemblies, and sealing components selected for the intended process media. Correct sizing and pressure rating are essential for dependable pressure regulation and protection of downstream equipment.

Adjustable Pressure Reducing Valves are used in water supply systems, industrial process lines, compressed air networks, steam installations and other applications where controlled downstream pressure is required. Depending on the valve construction, they can be specified for compatible liquids, gases or steam within their rated pressure and temperature limits. Important selection factors include inlet pressure, required outlet pressure, flow rate, pressure differential, media type, operating temperature, connection size and material compatibility. Buyers should also verify the adjustment range, pressure stability under changing demand and whether the application requires a pressure gauge or additional downstream safety protection. A pressure reducing valve regulates downstream pressure but should not be treated as a substitute for a pressure relief valve where overpressure protection is required. Selecting the appropriate adjustable pressure reducing valve helps support stable system pressure, reliable equipment operation and efficient process control within the specified operating conditions.

Frequently Ask Questions

Yes. Specially designed steam pressure reducing valves are available for high-temperature steam systems. The valve material and sealing components should be selected according to the operating pressure and temperature.
Selection depends on inlet pressure, required outlet pressure, flow rate, valve size, operating temperature, media type, end connection, and body material to ensure safe and efficient operation.
The outlet pressure is adjusted by turning the adjustment screw or spring adjustment bolt located on the top of the valve. Clockwise generally increases the outlet pressure, while counterclockwise decreases it.
