DIN/BS/JIS/CE Metal Seal Hard Seal DN50/65/80/125 Cast Steel Wcb Forged Steel A105 CF8 Triple Offset Eccentric Butterfly Valve for Oil Water Gas

Kamroo Valve 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.

Triple offset butterfly valves are commonly applicating in a variety of industries, including:

1. Oil and Gas: Triple offset butterfly valves applicate in the oil and gas industry. For pipeline isolation, compressor stations, and refining processes.
2. Chemical: Triple offset butterfly valves are popular in chemical plants for applications. Such as corrosive and abrasive fluid handling, high-temperature services, and toxic gas handling.
3. Power Generation: Triple offset butterfly valves play an important role in power generation. For applications such as steam isolation, turbine bypass, and cooling water control.
