Triple offset butterfly valves are a type of valve that has three offset shafts. The first offset is the shaft offset from the centerline of the valve. The second offset is the shaft offset from the sealing surface. And the third offset is the cone angle offset from the sealing surface. This design allows the valve to achieve a zero-leakage seal, even at high pressures and temperatures.
Triple offset butterfly valves offer several features and benefits that make them high-performance solutions for industrial applications. These include:
Triple-Offset valves use three offsets to create a high performance and low friction seal.
The fundamental feature of the valve design is the three offsets, these are highlighted in the 3D figure below:
Offset 1 - an offset between the shaft centreline and seat
Offset 2 - an offset between the centreline of the pipeline and the valve shaft
The valve shaft is offset from the centre line in both the X and Y axis, which makes up the first two offsets.
Offset 3 - An angular offset of the seating faces creating the conical geometry of the seat faces
The third offset consists of a conical angle on the sealing faces meaning the sealing faces only come into contact at the point of sealing.
Proper maintenance is essential for ensuring the optimal performance and lifespan of triple-offset butterfly valves. Maintenance tasks include:
