damper control butterfly valve

There are no connecting rod, bolt and other components in its interior, so some component problems will not occur in the use process, so the failure rate is very low. It's very convenient to use. It is a reliable valve device. Because there is a large gap between the butterfly plate and the valve body of Stainless Steel Damper Control Butterfly Valve, there is enough expansion space, so in the process of use, it can effectively prevent the thermal expansion and cold contraction caused by the temperature change, and the butterfly plate will not be stuck. Because of the wide selection of materials, this kind of ventilation butterfly valve also has the characteristics of high temperature resistance, there will be no friction when opening and closing, and the service life is extremely long.
