Elastic metal seal butterfly valve is a national key new product, high performance elastic metal seal butterfly valve adopts a double eccentric and a special oblique cone oval seal structure. To solve the traditional eccentric butterfly valve in the opening and closing of the instantaneous sealing surface is still in the sliding contact friction problems, to achieve the butterfly plate in the open instant sealing surface that is separated from the contact that is sealed effect, to extend the service life, sealing performance of the most Good purpose. 
 
Usage:
For the sulfuric acid industry in the gas pipeline: the front of the blower inlet and outlet, connecting the fan inlet and outlet, electric de-fog series and the valve, S02 main blower inlet and outlet, converter adjustment, preheater inlet and other adjustment and cut off the use of gas. 
It is the preferred brand of sulfur for sulfur-based sulfuric acid plant. It is considered by the users as follows: good sealing performance, light operation, deputy corrosion, high temperature resistance, easy operation, Flexible, the use of safe and reliable butterfly valve, has been a large number of popular use.
 
Is also widely used in: chemical, petrochemical, smelting, medicine, food and other industries SO2, steam, air, gas, ammonia, CO2 gas, oil, water, salt, lye, sea water, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid Such as regulators and shutoff devices. 
 
Structural features: 
① three-way eccentric unique design so that no friction between the sealing surface drive, extending the valve life.
② The elastic seal is generated by the torque. 
③ clever wedge design so that the valve has more and more tight automatic sealing function, sealing between the compensation, zero leakage. 
④ small size, light weight, light operation, easy to install. 
⑤ According to user requirements configuration pneumatic, electric devices, to meet the needs of remote control and program control. 
⑥ replacement parts material can be applied to a variety of media, and can be anti-corrosion lining (lining F46, GXPP, PO, etc.). 
⑦ continuous structure diversification: the folder, flange, butt welding.
