Overview
DN350-DN1400 fixed ball valves feature a fixed ball and piston-type seat structure, offering better resistance to pipeline stress. The central axis incorporates a blow-out prevention design and a replaceable central axis sealing system. A bidirectional double-seal mechanism ensures superior sealing performance under both high and low pressures. The bidirectional quadruple seal tightly adheres to the ball, enhancing the valve's sealing reliability. The valve body is equipped with a bottom drain and pressure relief hole, ensuring safe operation of the valve.
