Three eccentric laminate hard seal flange butterfly valve is a long-life, energy-saving butterfly valve. Its structure adopts the three-dimensional core principle design, and the valve seat adopts the laminate stainless steel with graphite structure of hard and soft sealing compatibility, with exquisite processing and advanced technology. This product is composed of valve body, butterfly disc, laminate seal as valve seat, valve stem, transmission mechanism and other main components. It is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage pipeline.

Metal to Metal Seat Butterfly Valve-Features

There are three eccentrics (offsets): the first eccentric, the shaft deviated from the centerline of sealing face; The second eccentric, the shaft deviated from the centerline of pipe and valve; The third eccentric the distinctive included angle between oblique taper angle of eccentric seat and centerline of pipe, thus making seat completely disengaged from the sealing ring during the whole process of open and close. This structure not only uses cam effect, but also eliminates the possibility of abrasion and leakage.

Metal to Metal Seat Butterfly Valve

1. Elastic property of composite metal sealing ring to perform zero leakage.
2. Torque seal to ensure two-way zero leakage.
3. STL one piece hard surface seat may be adapted to many working conditions, which is featured by long service life and easy maintenance.
4. One piece cast body, face to face dimensions conforming to ISO 5752, ASME B16.10 and API 609, replacement to high performance butterfly valves and other types of valves, easy and flexible installation.
5. Intrinsically fireproof property thanks to all metal structure and leak tight performance.
6. Anti-blowout stem for high dependability, completely conforming to API 609
7. The stem of triple eccentric butterfly valve is a shaft, and the stem and disc are connected by key or pin-key combination.
