Ball valve

leverflangestainless steel

The structure of the directional valve is composed of 1 valve body, 1 platform support and 4 side valve covers combined with fixed ball core. The ball core is connected by the valve rod, and the axis can be rotated 90 degrees to realize the function of opening and closing. It is mainly used for pipeline switch, pipeline shunt, and can also design ball core X-shaped opening to achieve medium reversing function. Design standards: ANSI B16.34,API608.
