General Description:
High performance double eccentric butterfly valves are widely used in industrial pipeline systems requiring reliable sealing, low operating torque, and long service life.
Compared with concentric butterfly valves, double eccentric butterfly valves provide:
These valves are commonly used in:
FTK Valve provides high performance double eccentric butterfly valves designed for stable flow control and demanding industrial applications.
A double eccentric butterfly valve, also called a double offset butterfly valve, features a disc and shaft structure designed with two offsets.
The two offsets include:
This design allows the valve disc to reduce direct friction with the valve seat during operation.
As a result, the valve achieves:
Double eccentric butterfly valves are widely used in medium and high-performance industrial systems.
The double offset design reduces friction between the disc and seat during opening and closing.
This helps:
Double eccentric butterfly valves provide more reliable sealing than concentric butterfly valves.
Suitable for:
Reduced friction lowers operational torque.
This improves:
Reduced mechanical wear helps improve:
Double eccentric butterfly valves are commonly used in:
Humans discovered that moving giant volumes of fluid becomes easier when the metal parts stop grinding themselves to death every cycle. Industrial progress truly is a long argument against friction. ⚙️
