Water Pressure Reducing Valve (PRV)

ALIS Valves offers Water Pressure Reducing Valves (PRVs) for applications requiring reliable downstream pressure regulation and protection of water distribution systems. These valves are designed to reduce higher inlet pressure to a preset, lower outlet pressure and maintain it within the valve’s operating range as flow conditions change. By controlling excessive water pressure, they help protect pipelines, fittings, plumbing fixtures and connected equipment from pressure-related stress. Depending on the design, the valve may use a diaphragm or piston-operated mechanism to adjust the flow passage and regulate downstream pressure automatically.

Water Pressure Reducing Valves are suitable for residential and commercial plumbing systems, water treatment plants, municipal water supply networks, irrigation systems and industrial water distribution applications. They help maintain suitable pressure levels, improve system stability and reduce the risk of damage caused by excessive water pressure. Important selection factors include inlet pressure, required outlet pressure, flow rate, water temperature, pipeline size, body material, connection type and maintenance requirements. Selecting the appropriate PRV according to system specifications supports dependable pressure control, efficient water distribution and reliable operation under the intended working conditions.
