We offers a comprehensive range of Triple-offset Butterfly Valves in a variety of body styles and materials to address critical process requirements in diverse industries such as hydrocarbon, power, chemicals & fertiliser, water, etc. The product range covers valves in ASME classes up to 1500, in sizes up to 100" (2500 mm), in carbon steel, stainless steel and alloy steels, suitable for temperatures from -196°C to 538°C. Based on customer requirements, valves in higher pressure classes, larger sizes and other materials are also offered.
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.
