Eccentric metal seal butterfly valve is used in gas cleaning system for dealing with media such as air, coal gas and coal gas containing dust, etc.
The eccentric structure of the valve avoids leakage. The surface of the eccentric metal seal butterfly valve is coated with metals, so they can be used in harsh outdoor environment for long term.
Material: Stainless steel, alloy steel
