Triple eccentric (triple offset) metal seated design for tight shut-off under high temperature and high pressure conditions up to around 550 °C. kekegroup.en.made-in-china.com
Hard-faced stainless steel / cobalt-based alloy sealing surfaces provide excellent wear, erosion and high-temperature resistance, extending service life in severe service. kekegroup.en.made-in-china.com
Minimal seat friction thanks to the triple offset geometry - the disc and seat are almost free from rubbing during opening and closing, reducing torque and seat wear. kekegroup.en.made-in-china.com
Bi-directional sealing with laminated metal seal structure, combining the advantages of metal and soft sealing for both low and high temperature applications. kekegroup.en.made-in-china.com
JIS-compliant design and testing (design, flange dimensions, face-to-face, pressure test) for reliable performance in international pipeline systems. kekegroup.en.made-in-china.com
Wide size and connection range: DN100-DN800 with flanged ends (wafer and welded ends also available for extended DN25-DN2500 series). kekegroup.en.made-in-china.com
The valve is suitable for medium temperatures up to approximately 550 °C, and is widely used in metallurgy, power plants, petrochemical installations and industrial drainage pipelines as an ideal device for regulating flow and isolating media. kekegroup.en.made-in-china.com
This triple eccentric (triple offset) metal seated rotary butterfly valve is designed for reliable shut-off and throttling in high-temperature and high-pressure service. By adopting an advanced three-dimensional eccentric sealing structure, the disc moves away from the seat during opening and closing, so there is almost no friction between the sealing surfaces. This greatly reduces operating torque, minimizes seat wear and ensures long service life. kekegroup.en.made-in-china.com

Triple eccentric sealing structure - The unique offset between the shaft center, disc center and seat cone axis eliminates scraping between disc and seat, providing a "the more it closes, the tighter it seals" function. kekegroup.en.made-in-china.com
Laminated metal seal - The disc uses a multi-layer composite metal seal ring, combining metal and soft layers to deliver excellent sealing performance under both low and high temperature conditions. kekegroup.en.made-in-china.com
Hard-faced sealing surfaces - The seat and disc sealing surfaces are welded with stainless steel and cobalt-based alloy, offering outstanding wear resistance, erosion resistance and long service life. kekegroup.en.made-in-china.com
Low operating torque and smooth operation - The compact construction and optimized eccentric geometry make operation light and flexible, even under high line pressure. kekegroup.en.made-in-china.com
The valve is designed and manufactured according to JIS B2064, with flanged end connections conforming to JIS B2220, face-to-face dimensions to JIS B2002 and pressure testing to JIS B2003. Pressure classes and main flange dimensions are provided for PN40 and PN64 with detailed bolt patterns, meeting various high-pressure pipeline requirements. kekegroup.en.made-in-china.com
Nominal size range (model): DN100-DN800 (series available from DN25-DN2500) kekegroup.en.made-in-china.com
Body materials: Ductile iron, cast iron, stainless steel according to service conditions kekegroup.en.made-in-china.com
Seat options: Metal seat (standard for high temperature) or soft seat such as EPDM for normal temperature services kekegroup.en.made-in-china.com
Connection types: Flange (standard for this model); wafer and welded ends are also available for the extended series kekegroup.en.made-in-china.com
Media: Water, air, gas, oil and various industrial liquids kekegroup.en.made-in-china.com
Actuation: Worm gear operator as standard; electric, pneumatic or hydraulic actuators available on request
Thanks to its high-performance metal seated design and triple eccentric structure, this butterfly valve is widely applied in:
Steel and metallurgy processes (high-temperature media and flue gas)
Power generation and boiler systems
Petrochemical and refinery piping
Industrial water treatment and drainage pipelines
OEM and ODM services are available. Keke Group can provide customized dimensions, materials, end connections and actuation packages according to your specific project requirements and technical standards.
