Triple-Offset Butterfly Valve

The Triple-Offset Butterfly Valve features a triple-offset structure and a hard metal seal, reducing friction between the valve disc and seat during opening and closing, and minimizing wear on the sealing surface. It is widely used in oil and gas, petrochemical, power generation, and chemical processing industries.

Design Standards: Supports design standards such as API 609 and EN 593, configurable according to project specifications.

Testing Standards: Performs shell and seal tests according to API 598, ISO 5208, and EN 12266.

Flange Standards: Compatible with flange standards such as ASME B16.5, ASME B16.47, and EN 1092-1.

Special Compliance: Fire Safe, Fugitive Emission, CE/PED, and other testing or certifications are available upon request, depending on product and project requirements.

Low-Friction Design: The triple-eccentric structure reduces frictional contact between the valve disc and seat, lowering sealing surface wear and operating resistance, suitable for long-term opening and closing conditions.

Metal Sealing: Metal sealing reduces the limitations of soft sealing materials due to high temperatures, allowing for material selection based on media and temperature.

Reliable Shutoff: The valve disc and seat form a seal through closing torque, with sealing performance tested according to API 598 or ISO 5208.

Large-Size Application: Butterfly valves are compact and relatively lightweight, suitable for shut-off and isolation of large-diameter industrial pipelines.

Material Traceability: Materials are verified according to order requirements, and material traceability is established through Heat Number and MTC. EN 10204 3.1 documentation is available.

Dimensional Inspection: Valve body, valve disc, valve stem, sealing surfaces, and connection dimensions are inspected to ensure compliance with drawings and order requirements.

Non-Destructive Testing (NDT): UT, PT, MT, or RT testing is performed according to product and project requirements, and corresponding reports are provided.

Pressure Testing | Before shipment, the body and seals undergo testing according to applicable standards, and the results are recorded.

Third-Party Inspection | Supports inspection and testing by third-party organizations such as SGS, TUV, and BV.

CNC Machining: Precision machining of valve bodies, valve discs, and sealing components to control key dimensions and assembly accuracy.

Size & Pressure Customization: Supports customization of dimensions, pressure ratings, connection methods, and structural lengths based on datasheets, drawings, and project specifications.

Material Selection: Materials such as Carbon Steel, Stainless Steel, and Duplex are selected based on media corrosivity, temperature, and pressure.

OEM / Private Label: Supports customization of nameplates, logos, colors, packaging, and related documents to meet the purchasing needs of distributors and wholesalers.

Export Packaging: Wooden crates or pallets are used for packaging according to product size, protecting flanges, seals, and actuators.

Product Identification: Model, Size, Pressure Class, Tag Number, Weight, etc., can be provided.

Documentation: MTC, Pressure Test Report, NDT Report, Inspection Report, COC, etc., can be provided according to the order.
