Pneumatic high-pressure ball valve has the action of rotating 90 degrees, and the plug body is spherical with a circular through-hole or channel passing through its axis. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of media. They can be tightly closed with a 90 degree rotation and a small rotational torque. Ball valves are suitable for use as switches and shut-off valves, but recent developments have designed them to have throttling and flow control functions, such as V-shaped ball valves. Pneumatic V-shaped ball valve is a control valve with a right angle rotating structure, which can be divided into pneumatic V-shaped regulating ball valve and pneumatic V-shaped cut-off ball valve. It is used in conjunction with a valve positioner to achieve proportional adjustment.

The main characteristics of high-pressure ball valves are compact structure, good sealing performance, simple structure, easy maintenance, sealing surface and spherical surface are often in a closed state, not easily eroded by media, easy to operate and maintain, suitable for general working media such as water, solvents, acids, and natural gas, and also suitable for media with harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. They are widely used in various industries. The valve body of a ball valve can be integral or modular. The valve body form includes integral forged valve body (within DN50), three-stage forged valve body (above DN50), connection methods include flange type, welding type, threaded type (applicable to PN45MPa or less), and adopts O-shaped spherical valve core. The flow characteristics are approximate quick opening characteristics.
