Pressure Sustaining Control Valve

Overview

Pressure Sustaining Control Valve is a hydraulic control valve designed to maintain a predetermined upstream pressure by automatically adjusting its opening in response to system conditions. When pressure drops below the set point, the valve remains closed or partially closed to sustain pressure; when pressure exceeds the set point, the valve opens to relieve excess pressure. This function ensures stable upstream pressure, protects critical equipment, and supports balanced system performance. Pressure sustaining valves are commonly used in water distribution, pump stations, industrial processes, and fire protection systems to maintain pressure integrity and prevent system collapse.

Utility Priority

The Pressure Sustaining Control Valve serves a vital utility in preserving upstream pressure within a pipeline system by restricting flow until a minimum set pressure is maintained. Its primary priority is to ensure system stability, protect upstream equipment such as pumps and filters, and maintain adequate pressure for critical processes or zones. This valve is widely applied in water supply networks, pump stations, industrial processing systems, and fire protection installations, where consistent upstream pressure is essential to avoid system imbalance, equipment failure, or service interruptions.
