The elastic metal seated butterfly valve is a new national key product. The high-performance elastic metal seated butterfly valve adopts a double eccentric and a special oblique cone elliptical sealing structure. It solves the problem that the sealing surface of the traditional eccentric butterfly valve is still in sliding contact friction at the moment of opening and closing at angles between 0° and 10°. It realizes the effect that the sealing surface of the butterfly plate is separated at the moment of opening, and the effect of sealing is achieved when the contact is closed to achieve the purpose of prolonging the service life and optimizing the sealing performance.
 

                   
Applications
Elastic metal seated butterfly valves are not only used in gas pipelines in the sulfuric acid industry and sulfur burning, conversion, and dry suction processes in the sulfuric acid system, but also widely used in chemical, petrochemical, smelting, pharmaceutical, food and other industries. It is used as a regulating and intercepting device on the pipelines of SO2 gas, steam, air, gas, ammonia, CO2 gas, oil, water, brine, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other media.
 
Structural Characteristics
1. The unique design of three-way eccentricity enables frictionless transmission between the sealing surfaces and prolongs the service life of the valve.
2. An elastic seal is created by torque.
3. The ingenious wedge-shaped design enables the valve to have an automatic sealing function that becomes tighter and tighter, and the sealing surface has compensation and zero leakage.
4. The elastic metal seated butterfly valve has small sizes, light weights, easy operation and installation.
5. Pneumatic and electric devices can be configured according to the user's requirements to meet the needs of remote control and program control.
6. It can be applied to various media after changing the material of the parts.
7. Diversified structure: wafer, flange and butt welding
