Our butt-welding type two-way pressure-bearing butterfly valve not only adopts the conventional three eccentric structure, but also combines the movable seat principle of fixed ball valve, which more effectively guarantees the sealing performance of reverse pressure-bearing, and really achieves 100% bi-directional pressure-bearing.

The valve body adopts molding seamless steel pipe welding, more effective solution to the potential leakage of castings, its unique structure, novel design, easy opening and closing, long service life.
