Introduction:

Pneumatic valve can be tightly closed with only a 90 degree pneumatic rotation and a small turning torque. The completely equal valve body cavity provides a small resistance and straight flow path for the medium. It is generally believed that ball valves are most suitable for direct opening and closing use, but recent developments have designed ball valves to have throttling and flow control functions. The main characteristic of ball valves is their compact structure, easy operation and maintenance, suitable for general working media such as water, solvents, acids, and natural gas, and also suitable for harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. The valve body of a ball valve can be integral or modular.

Function:

The working principle of stainless steel pneumatic ball valves is to rotate the valve to make the valve unobstructed or blocked. Pneumatic ball valves are lightweight, small in size, and can be made into large diameters. They have reliable sealing, simple structure, and convenient maintenance. The sealing surface and spherical surface are often in a closed state and are not easily eroded by media. They are widely used in various industries.

Pneumatic flange ball valves are mainly used in pipelines for fast cutting speed, distribution, and changing the flow direction of the medium. Pneumatic ball valve is a new type of valve widely used in recent years, which has the following advantages:

1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length.

2. Simple structure, small size, and light weight.

3. Tight and reliable. Currently, plastic is widely used as the sealing surface material for ball valves with good sealing performance, and it has also been widely used in vacuum systems.
4. Easy to operate, quick to open and close, with only a 90 ° rotation from full open to full close, facilitating remote control.
5. Convenient maintenance, pneumatic ball valves have a simple structure, and the sealing ring is generally movable, making disassembly and replacement more convenient.
When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.
7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be applied from high vacuum to high pressure.
Pneumatic three piece ball valves have been widely used in various departments such as petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets, as well as in people's daily lives.
