Laminated Seat Ring Triple Eccentric Stainless Steel Butterfly Valve With Gear Operation
Brief introduction:
The butterfly valve is operated by the disc rotating from 0° to 90°, can be applied to cut off or regulate the flow of medium.
The valve can be actuated by operating lever, handle wheel electric actuator or pneumatic actuator.
Widely used for potable water supply and distribution, waste water treatment, electric power plant, gas supply, warm-air system, smelting plant, ship building, textile, petroleum, chemistry, or other light industries.

What is triple offset design
1st eccentricity
The shaft is diverged from centerline of sealing surface.
2nd eccentricity:
The shaft is diverged from centerline of the pipeline and valve. These two eccentricities are designed for friction reduction between the valve seat and seal ring when opening and closing the valve.
3rd eccentricity
It makes the valve set completely separated from the seal ring through the geometric shape, during the whole process of opening and closing the valve. The special eccentric combination not only makes use of the cam effect, but also completely eliminates friction. It enables no friction between the valve seat and seal ring on the valve plate, to eliminate possible abrasion and leakage, in the 90°stroke of the valve.
