The double-flanged butterfly valve is designed to control the flow of liquids and gases. It is typically installed in industrial pipelines, connected on both sides by flanges. This design allows for safe use across different sections of the system. The disk inside the valve is rotated by a shaft, enabling the opening and closing of the valve.

The disk is rotated according to the direction of the fluid flow, and a sealing gasket ensures a tight shutoff. Additionally, the valve body is designed to be integrated, providing long-term durability. It can be operated with manual, electric, or pneumatic actuators, offering flexibility in control and operation for different system needs.

How Does a Double-Flanged Butterfly Valve Work?

The disk inside the valve is rotated around a central shaft to control the flow. By rotating the disk 90 degrees, the valve is either fully opened or closed. This motion is based on a simple rotational principle. Sealing is achieved through EPDM or Viton seals.

Control can be performed via a manual handle, gearbox, or an automation system. This allows the system to be safely managed without the need for remote intervention. Additionally, the low torque requirement helps in achieving energy savings.

Where are Flanged Butterfly Valves Used?

Double-flanged butterfly valves are widely used across many industries. They are commonly preferred in water and wastewater treatment plants. In chemical and petrochemical facilities, they are used to control fluids containing acids and bases. These valves also facilitate flow management in power plants and HVAC systems, ensuring efficient operation and regulation of fluids.

Additionally, double-flanged butterfly valves are used in maritime, food, and pharmaceutical industries due to their hygienic design. They provide a secure solution in pipeline maintenance and system separation points. Thanks to their high pressure and temperature resistance, they can operate efficiently under challenging conditions.
