Pressure sustaining valve

الوصف

Pressure sustaining valves are used to maintain constant pressure above the valve handle. These valves are usually used at the intersection of pipelines, because if there is less resistance and more consumption in an intersection in one direction compared to the other direction, the problem of water leakage will arise. Therefore, by installing the constant pressure valve on the pipeline that shows less resistance to the flow, the pressure is maintained at the intersection of the pipeline so that the water can be directed to the path that shows more resistance to the flow.
