The Diaphragm Control Valve is an automatic control valve designed to deliver full sealing, smooth modulation and unobstructed flow using a flexible rubber membrane. The diaphragm acts as the only moving and control element, managing opening, closing and modulation of the valve.

In the closed position, the valve ensures complete tight sealing thanks to the elastomeric membrane. When open, it provides minimal pressure drop and a clear flow path, allowing efficient operation at the desired opening level.

The valve can be operated using line pressure or an external pressure source, making it suitable for a wide range of control applications. Since the design eliminates rotating shafts, bearings and traditional sealing gaskets, the valve offers exceptional reliability, reduced wear and long service life.

Diaphragm control valves are widely used in pressure control, flow regulation and water network automation, where precise and maintenance-free operation is required.
