Triple Eccentric Butterfly Valve
The triple eccentric butterfly valve features three key eccentricities: the valve stem, the valve disc, and the conical sealing surface between the disc and seat. This design enables friction-free contact during closure, significantly extending valve life. The elastic sealing ring, whether mounted on the valve seat or disc, adjusts automatically under closing force to ensure uniform pressure distribution and reliable sealing. Its slight deformation further enhances the seal's effectiveness. This valve is widely used in metallurgy, power generation, petrochemicals, water systems, and municipal pipelines for flow regulation and fluid shutoff.

Triple Offset Butterfly Valve
Triple offset metal sealing butterfly valve uses the three eccentric structure with multi-layer metal seal or pure metal sealing ring, different sealing materials are being used according to the different temperature request from end user.The structure of valve sealing ring that was formed after machining for triple eccentric butterfly valve is oblique cone type, the purpose of which is to let the disc open in a subtle angle and seat sealing surface can be completely separated from the sealing surface of disc, thus to reduce the friction of sealing surface during the open and close.
Triple Offset Frictionless Design
- Offset 1: Offset for seat seal and the rotation center of stem.
- Offset 2: Center of pipe and disc.
- Offset 3: Seat sealing angle center line and flow passage center.
- The triple offset of butterfly valve ensures the valve disc is completely separated from seat sealing surface while open in a slightly angle which could reduce the friction of sealing surface during open and close and opening torque as well as prolong the service life of the sealing surface.
- Our metal sealing butterfly valve adopts multi-layer sealing ring to achieve the valve seal, the multi-layer seal ring is generally made of stainless steel and graphite combination The pure metal sealing can be used for special medium or high temperature.
Seat Structure
- Low Operating Torque: Our butterfly valves combine three offsets. Standard sealing is graphite + metal. Optional PTFE + metal combinations are available for different temperatures and media, using flexible laminated metal and graphite to ensure a tight, uniform seal and reduce operating torque.
- Zero Leakage: Laminated seal rings are self-aligning, allowing the valve to meet zero leakage per API 598.
- Fire-Safe Design: Standard valves are not soft-seated and meet API 607 fire-safe requirements.
- Anti-Blowout Shaft: Double anti-blowout design meets API 609 and ASME B31.1.
- Top Retention: Packing gland follower retains the stem.
- Bottom Retention: T-shaped collar prevents stem blowout.
