Flow Control and Pressure Reducing Valve
Dual-function control valve combining flow limitation and pressure reduction in a single integrated unit for efficient system control.
Overview
A Flow Control and Pressure Reducing Valve is a hydraulically operated, self-actuated control valve designed to limit flow to a preset maximum value while simultaneously reducing downstream pressure to a safe, constant level.
By combining flow regulation and pressure reduction in a single valve, it ensures efficient system control, protects downstream infrastructure, and improves overall network performance.
Key Features
- ✓Dual-function operation
- ✓Flow limitation and pressure reduction
- ✓Fully automatic operation
- ✓No external power required
- ✓Compact and efficient design
Working Principle
The valve operates automatically using line pressure, without external power.
- ✓The pressure reducing function maintains a constant preset downstream pressure, irrespective of inlet pressure variations.
- ✓The flow control function limits the maximum flow rate to the set value, even during high-demand or pressure surge conditions.
- ✓The valve continuously modulates to respond to changes in flow demand and pressure, ensuring stable and balanced system operation.
Key Functions
- ✓Reduces downstream pressure to a preset value
- ✓Limits maximum flow rate
- ✓Protects pipelines and equipment from over-pressure and over-flow
- ✓Improves pressure zone management
- ✓Ensures stable and efficient water distribution
