‌Pneumatic flanged ball valves are a valve assembly that combines a ball valve with a pneumatic actuator. They operate by using compressed air to rotate the ball within the valve body, thereby opening or closing the pipeline. When the passage on the ball aligns with the valve body's inlets and outlets, the valve is open and fluid can pass through; after the ball rotates 90 degrees, the passage is perpendicular to the valve body's inlets and outlets, the valve is closed, and fluid flow is blocked.‌

Structural Features

The pneumatic flanged ball valve features a compact structure, easy operation, and maintenance. The valve body can be either integral or assembled, suitable for various working media, including general media such as water, solvents, acids, and natural gas, as well as media under harsh working conditions like oxygen, hydrogen peroxide, methane, and ethylene. The pneumatic actuator typically includes cylinders, pistons, valves, and control elements, converting compressed air energy into mechanical kinetic energy upon receiving control signals, thereby rotating the valve stem and the connected ball.

Application Scenarios

Pneumatic flanged ball valves are widely used in the oil, chemical, power generation, papermaking, nuclear energy, aviation, and daily life industries. Their quick cut-off and flow regulation functions make them particularly important in industrial applications requiring rapid response. Additionally, pneumatic flanged ball valves are suitable for various fluid media such as gases, liquids, and steam, and can operate under different temperature and pressure conditions. The pipe diameter range spans from a few millimeters to several meters.
