The electric flanged soft seal butterfly valve is an essential component in fluid control systems, offering numerous advantages for various industries such as water treatment, HVAC, chemical processing, and oil and gas. This valve type is designed to regulate the flow of liquids and gases through a pipeline, ensuring optimal performance, reliability, and minimal leakage. By integrating electric actuation, the valve can be remotely controlled, which is crucial in modern automation systems.

Structure and Functionality

The electric flanged soft seal butterfly valve consists of several key components: the valve body, the disc, the actuator, and the seal. The body of the valve is typically made from materials such as cast iron, stainless steel, or ductile iron, chosen for their strength and durability in handling various types of fluids. The butterfly disc is the central part of the valve, rotating to control the flow. It can either completely block or allow the passage of fluids depending on its position. The valve’s most distinguishing feature is its “soft seal.” This term refers to the resilient sealing material, typically made from elastomers like EPDM or NBR, which ensures a tight shut-off when the valve is in the closed position. This soft seal provides the valve with excellent resistance to pressure and ensures minimal leakage, making it ideal for systems requiring high performance.
