I have introduced some basic features of pneumatic ball valve
s before. Today, I will introduce the principle of pneumatic V-shaped ball valves. The so-called pneumatic V-shaped ball valve refers to the installation of a pneumatic actuator on the ball valve. The execution speed is relatively fast, and no manual operation is required. The principle of the pneumatic V-type ball valve: It can be firmly closed with only the operation of rotating 90 degrees with air and a small rotating torque. The completely equal valve body cavity has little resistance to the medium and provides a straight flow path. Ball valves are considered the most suitable for direct opening and closing, but with recent developments, ball valves are designed to control throttling and flow. The main feature of the ball valve is its compact structure, convenient operation and repair, and it is suitable for general working media such as water, solvent, acid, and natural gas. In addition, it is also suitable for medium with harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. The valve body can be integral or combined. The principle of the pneumatic V-shaped ball valve is to turn the spool to open or close the valve. Aerosol switches are light, small in size and can be large in diameter. Reliable sealing. Simple structure and convenient repair. The sealing surface and spherical surface seal well. Pneumatic V-shaped ball valve and plug valve are the same type of valve, only their closing is a ball, and the ball is a valve that is opened and closed by rotating the center line of the valve. The advantages of pneumatic V-shaped ball valve: 1. The fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length. 2. Simple structure, small size and light weight. 3. Tight and reliable, the sealing surface material of the ball valve is widely used in plastic, and the sealing performance is good, and it has also been widely used in vacuum systems. 4. Easy to operate, open and close quickly, just rotate 90° from fully open to fully closed, which is convenient for long-distance control. 5. The maintenance is convenient, the pneumatic ball valve has a simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace. 6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the sealing surface of the valve will not be eroded when the medium passes through. 7. Wide range of applications, diameters ranging from small to several millimeters, large to several meters, and can be applied from high vacuum to high pressure. Today's pneumatic V-shaped ball valve is introduced here. If you still have any questions, you can consult Lianke Valve Co.,Ltd. Contact: +86-577-8585 9626.
