Flow Control Valve
Model-AD-400 FCV
Overview
A Flow Control Valve is a hydraulically operated, self-actuated control valve designed to maintain a constant preset flow rate in a pipeline, regardless of variations in upstream or downstream pressure.
The valve ensures accurate flow regulation, protects downstream systems, and improves overall network efficiency and stability.
Key Features
- ✓Constant flow rate control
- ✓Automatic flow regulation
- ✓No external power required
- ✓Protects downstream systems
- ✓Improves network efficiency
Working Principle
The valve operates automatically using line pressure, without the need for external power.
- ✓The valve continuously senses the flow rate through an orifice or flow pilot system.
- ✓If the flow exceeds the preset value, the valve modulates toward closing to restrict flow.
- ✓When the flow falls below the set value, the valve opens proportionally to allow the required flow.
This continuous modulation maintains a constant flow rate under changing system conditions.
Key Functions
- ✓Maintains constant preset flow
- ✓Protects downstream pipelines and equipment
- ✓Prevents excessive flow and system imbalance
- ✓Improves water distribution efficiency
- ✓Ensures stable and controlled operation
Main Components
- ✓Main Control Valve Body (Diaphragm Type)
