气动对夹式硬密封蝶阀
Elastic metal seal butterfly valve is made of "U" shaped stainless steel seal valve, whose precision elastic seal ring contacts with the chrome-plated and polished sealing surface of the butterfly plate, and as it is resistant to high temperature, high pressure and low temperature, it can be widely applied to pipelines with various media whose temperature ≤500℃ in heating system, water supply and coal gas system to regulate flow and cut of or connect fluid.
