Double eccentric butterfly valve is one of the most commonly used valves in the world today. They are highly efficient devices widely used in many different industries to control the flow of liquids or gases. In this article, we discuss the main features of double eccentric butterfly valves and explore their applications in various industries.
What is a double eccentric butterfly valve?
A double eccentric butterfly valve is a valve in which the disc or plate is mounted on an axis that deviates from the center of the valve body. This provides a double eccentric movement of the disc as it rotates. The valve disc is circular and rotates around the central axis of the valve body when rotating, forming an eccentric seal around the valve seat.
Main features of double eccentric butterfly valve
The double eccentricity is a key feature of this valve which makes it unique. Other features include:
1. Fast running speed
The quick operation of the double eccentric butterfly valve makes it ideal for applications requiring fast opening and closing times.
2. Low maintenance
Double eccentric butterfly valves require very low maintenance as they are designed with few parts that are easy to replace or repair.
3. Airtight
The double eccentric movement of the disc ensures a tight shutoff of the valve, making it ideal for applications requiring high precision.
4. Two-way flow
Double eccentric butterfly valves offer bidirectional flow capability, which means they can control the flow of liquids or gases in both directions.
