Purpose
The butt-welded bi-directional sealing butterfly valve is mainly used in petroleum, chemical engineering, power station, metallurgy, papermaking, water heating, light industry and other fields, as a shutoff and regulation device on the pipeline.
Product characteristics
Our butt-welded bi-directional pressure-taking butterfly valve not only adopts the conventional triple-eccentric structure, but also combines the movable seat principle of the fixed ball valve, which can guarantee the sealing performance under reverse pressure bearing more effectively, and truly achieve bi-directional pressure bearing of 100%. The valve body is welded with formed seamless steel pipe, which is more effective in solving the potential leakage of the casting. It has unique structure, novel design, convenient opening and closing and long service life.
