Pneumatic ball valves have a compact structure and are easy to operate and maintain. Suitable for general working media such as water, solvents, acids, and natural gas, as well as media with harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. The ball valve body can be integral or modular, and is opened and closed by the rotation of the valve core driven by a pneumatic actuator.
The principle of pneumatic ball valve: advantages of pneumatic ball valve. Pneumatic ball valve and plug valve belong to the same type of valve, except that its closing part is a sphere, which rotates around the center line of the valve body to achieve opening and closing. Principle of Pneumatic Ball Valve
Pneumatic ball valves are mainly used in pipelines to cut off, distribute, and change the direction of medium flow.
Pneumatic ball valve is a new type of valve, and its advantages include:
The fluid resistance is small, and its resistance coefficient is equivalent to that of a pipe segment of the same length. Simple structure, small size, and light weight. Good sealing performance. Plastic is widely used as a sealing surface material for ball valves, with excellent sealing performance, and is widely used in vacuum systems. Easy to operate, quick opening and closing, with a 90 degree rotation from fully open to fully closed, making it convenient for remote control. Easy to maintain, the pneumatic ball valve has a simple structure, and the sealing ring is generally movable, making disassembly and replacement relatively convenient. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium, and when the medium passes through, it will not corrode the valve sealing surface. Widely applicable, with diameters ranging from a few millimeters to several meters, suitable for applications ranging from high vacuum to high pressure. Because the power source of the ball valve is gas, the pressure is generally 0.4-0.7MPa. If the pneumatic ball valve leaks, compared to hydraulic and electric, gas can be directly discharged. Compared with manual and turbine rotary ball valves, pneumatic ball valves can be configured with larger diameters (manual and turbine rotary ball valves generally have diameters below DN300, while pneumatic ball valves can achieve larger diameters)
