High Temperature High Pressure Pn16 SS304 CF8 Triple Offset Rubber Lined Di/Ci/Wcb Body Double Flange Butterfly Valve

Product Description

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:

1. Zero Leakage: The triple offset design allows for a tight seal that prevents leakage, even in high-pressure and high-temperature applications. This reduces the risk of product loss, environmental damage, and safety hazards.
2. High Performance: Triple offset butterfly valves can handle high pressures and temperatures. Making them ideal for applications in industries such as oil and gas, chemical, and power generation.
3. Low Torque: The triple offset butterfly valve design requires less torque to operate, reducing the operation and maintenance cost.
4. Long Lifespan: Triple offset butterfly valves are highly durable. And resistant to wear and tear, resulting in a longer lifespan and reduced replacement costs.

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.
