Types of Pneumatic Diaphragm Control Valves
- Single Seated Control Valve – Provides precise flow control with tight shut-off, ideal for low to medium flow applications.
- Double Seated Control Valve – Designed for higher flow capacity with balanced forces for stable operation.
- Weir Type Diaphragm Valve – Commonly used for throttling and regulating flow in process industries.
- Straight Through Diaphragm Valve – Offers minimal flow resistance and is suitable for viscous fluids.
- Normally Closed (Air to Open) – Valve opens when air pressure is applied and closes when air is released.
- Normally Open (Air to Close) – Valve closes with air pressure and opens when air supply is removed.
How Pneumatic Diaphragm Control Valves Work
Pneumatic diaphragm control valves are widely used in industrial automation systems for accurate flow regulation and process control. These valves operate using compressed air to actuate a flexible diaphragm that controls the movement of the valve stem.
When air pressure is applied to the actuator, it moves the diaphragm and adjusts the valve position, either opening, closing, or modulating the flow of fluid. The valve responds quickly to changes in air pressure, allowing precise control over flow rates, pressure, and temperature in the system.
As a trusted pneumatic diaphragm control valve manufacturer in Mumbai, we design valves that ensure smooth operation, high reliability, and long service life across a wide range of industrial applications.
