Ball valve

pneumatically-operatedregulatingflange

The pressure plate type ball valve structure: it is composed of valve body, valve cover and ball core. The ball core is connected by the valve stem, and the axis can be rotated 90 degrees to realize the function of opening and closing. It is mainly used for pipeline switch, emergency cut-off, and ball core V-shaped opening can also be designed to achieve flow regulation function.
