Triple-offset butterfly valves are improved flow-control mechanisms that have three radial offsets for better sealing and efficiency while performing difficult operations. The design is friction-free, so it guarantees no leakage and high reliability for extreme pressures and temperatures.
Lianke Valve, a foremost player in the industry, has modified this technology in its fluorine-lined butterfly valve series to provide all-round solutions to tough industrial processes. This guide presents the technical dimensions, functions, and the advantages of the triple-offset butterfly valves to assist potential consumers in making the best possible choices for their intentions.
Key Takeaways:
The triple-offset design for a butterfly valve proves to be revolutionary in the advancements in technology for a butterfly valve. Allow us to explain how the three offsets are integrated:
First Offset: The centerline of the shaft is located to the rear of the casing’s centerline
Second Offset: The center of the shaft is located to the rear of the center sealing surface
Third Offset: The seal surfaces that face each other are created in rounded conical shapes.
The ornate shapes provide a cam mechanism that ensures that sealing surfaces do not touch each other until the last few degrees of the closing movement, thus minimizing wear and tear and increasing the life of the valves.
Various industries have more and superior uses for the triple-offset butterfly valve, mainly in regions where ordinary valves are unable to function optimally:
Lianke Valve makes fluorine-lined butterfly valves that have heated features in the industry such as:
The design of a triple-offset butterfly valve ensures that the given engineering standards are implemented that facilitate the best possible combination. Lianke valves fluorine-lined butterfly valves, like all the other valve manufacturers’ products, are designed to meet the requirements of the relevant international standards: GB/T12238 and API 6D – which assures the quality and uniformity of the product.
Body Materials: WCB, CF8, CF3, CF8M, CF3M
Lining Options: FEP, PFA, PTFE
Temperature Ranges:
Triple Offset: Metal-on-metal seal construction with no possible way for leakage to occur
Traditional: Employs soft seats and uses a friction seal
Triple Offset: No need for maintenance since there are no frictional forces
Traditional: Regular maintenance due to wear and tear
Triple Offset: Capable of withstanding severe service conditions
Traditional: Can only be used in moderate service conditions
Ensuring regular maintenance prolongs the efficiency of a unit:

Strainers are essential in protecting equipment by filtering out debris and impurities in pipelines. However, not all strainers are created equal. With a variety of options, the Y-type strainer and duplex basket strainer stand out as popular choices. Now, you may be asking, “Which strainer is best for my needs?” Explore this guide to discover […]
Wafer butterfly valves provide good flow control with minimal pressure drop when fully open, making them suitable for various applications, but they have limited sealing capability, which may not be ideal for high-pressure situations. In contrast, flange butterfly valves offer superior sealing performance, designed to handle higher pressures and more demanding conditions. Both types can […]
Understanding the Essential Component of Industrial Filtration Bag filter housings are commonly used in industries to eliminate particulates from liquids without compromising the industrial process. However, structures that are designed to hold a filter bag, which acts as the barrier, are also specialized tools for contaminated particle collection. Especially in industrial applications, bag filter housing […]
Lined ball valves feature a protective lining that offers superior corrosion resistance and can handle a wider range of temperatures, making them ideal for aggressive chemical applications. In contrast, unlined ball valves are typically made from metal and may require additional coatings for protection, leading to more frequent maintenance and a shorter lifespan in harsh […]
