Question 1

What is an eccentric butterfly valve?

Accepted Answer

The stem of an eccentric butterfly valve, sometimes referred to as an offset butterfly valve, is positioned away from the disc and valve body's midline. By lowering friction between the disc and the seat, this design improves sealing performance and longevity.

Question 2

How does the design of an eccentric butterfly valve

Accepted Answer

The design of an eccentric butterfly valve incorporates an offset stem that enhances performance and reduces wear compared to concentric butterfly valves. In an eccentric design, the stem is positioned off-center from the disc and valve body, creating a cam-like motion during operation. This offset allows the disc to move into and out of the seat with minimal friction, reducing wear and tear on the valve components. In double-offset and triple-offset designs, additional offsets further minimize contact between the disc and seat, ensuring a tighter seal and extending the valve's lifespan.

Question 3

What materials are eccentric butterfly valves made from?

Accepted Answer

Common materials include cast iron, ductile iron, carbon steel, stainless steel for the body; stainless steel or carbon steel for the disc and shaft; and soft elastomers (like PTFE) or metal for the seats.
