Operation
Long Life
Diaphragm Type Adjustable Pressure Stabilizing Valve is a hydraulically operated valve designed to reduce and stabilize downstream pressure in water supply and drainage systems. The diaphragm and pilot-control assembly continuously respond to changes in inlet pressure and flow conditions to maintain a controlled downstream pressure. The valve is commonly used in water supply systems, high-rise buildings, fire-fighting water systems and industrial water networks where stable downstream pressure is required.

Frequently Ask Questions
It is a hydraulic control valve designed to reduce and maintain downstream pressure at an adjustable level.
A pressure-reducing function lowers a higher inlet pressure to a lower downstream pressure. The stabilizing function focuses on maintaining that downstream pressure despite changes in inlet pressure and flow conditions.
The pilot-control system responds to the pressure change and adjusts the main valve opening to help maintain the required downstream pressure.
ALIS Valves manufactures and supplies industrial valve solutions in India. For this specific valve, the final size, pressure and material should be confirmed against the applicable ALIS product datasheet.
The valve uses a diaphragm and pilot-control circuit. Changes in inlet/downstream pressure cause the control system to adjust the main valve opening, helping maintain the required outlet pressure.
A filter helps prevent larger suspended particles from entering the pilot-control circuit, helping maintain reliable operation.
Yes. Diaphragm pressure-reducing/stabilizing valves are specifically used in water-supply systems where incoming pressure needs to be reduced and stabilized for downstream zones.
