Description
The Belimo D6..N series butterfly valves are essential components in various industrial applications, and they are known for their cost-effectiveness, lightweight design, and efficient flow regulation. These quarter-turn rotational motion valves are ideal for controlling the flow through pipelines by quickly opening or closing with a simple 90-degree rotation. Widely used in pharmaceutical, chemical, and food industries, as well as in water flow control for dams and hydroelectric power plants, butterfly valves offer both control and protection functions. Their versatility and reliability make them a preferred choice for managing flow in numerous applications, ensuring optimal performance and safety.

Operating Mode
The butterfly valve is opened or closed completely by an open/close rotary actuator. A commercially available controller connects continuous rotary actuators and move the valve to any desired position. The valve disk made of stainless steel is pressed into the soft-sealing EPDM seat by a rotary movement, ensuring a tight seal with minimal pressure loss when open, maximising the Kv value.
