DS(3/6/9)63H Butt-welded Triple Eccentric Bidirectional Sealing Butterfly Valve

Our company’s butt-welded bidirectional pressure-bearing butterfly valve not only adopts the conventional triple eccentric structure, but more importantly, it combines the movable seat principle of fixed ball valves, which more effectively ensures the sealing performance under reverse pressure and truly achieves 100% bidirectional pressure bearing. The valve body is assembled and welded with formed seamless steel pipes, which more effectively solves the potential external leakage problem of castings. In addition, it has a unique structure, novel design, easy opening and closing, and a long service life.
