Question 1

What is a double eccentric butterfly valve?

Accepted Answer

A double eccentric butterfly valve, also known as a double-offset butterfly valve, is a type of valve where the disc is offset from the center of the valve body and the pipe axis. This design reduces friction between the disc and the seat during operation, resulting in longer valve life and improved sealing performance.

Question 2

What are the primary uses of double eccentric butterfly valves?

Accepted Answer

Double eccentric butterfly valves are commonly used in industries such as water treatment, power generation, oil and gas, and chemical processing. They are ideal for applications requiring reliable sealing and durability under high-pressure and high-temperature conditions.

Question 3

How does the double eccentric design work?

Accepted Answer

The stem is offset from the valve bore centerline and also offset from the disc sealing surface. This allows the disc to lift off the seat early during opening, minimizing contact and friction, which extends valve life and reduces operating torque.
