Features of pneumatic three piece ball valve:
1. Pneumatic control valve Pneumatic three piece ball valve is simple in structure, small in size, light in weight, and low in fluid resistance. Its resistance coefficient is equal to that of pipe sections of the same length.
2. The pneumatic three piece ball valve is easy to maintain, the pneumatic ball valve is simple in structure, the sealing ring is generally movable, and it is easy to remove and replace.
3. Tight and reliable. At present, plastic is widely used as the sealing surface material of the ball valve with good sealing performance, and it has also been widely used in the vacuum system.
4. Convenient operation, fast opening and closing, 90 ° rotation from full opening to full closing, convenient for remote control.
5. It has a wide range of applications, ranging from a few millimeters to several meters in diameter, from high vacuum to high pressure. 6. When the valve is fully opened or closed, the sealing surface of the ball and valve seat is isolated from the medium. When the medium of the self operated regulating valve passes through, it will not cause erosion of the valve sealing surface.

How standard is the pressure rating of pneumatic butterfly valve in the consumption process
What is the pressure rating of pneumatic butterfly valve in the consumption process? Pressure range of stainless steel pneumatic butterfly valve: the pneumatic butterfly valve is the main pressure bearing part of the hose device in the pressure pipeline, and also acts as a sheath for the bellows. According to the pressure in the pipeline and the application site, one or more layers of stainless steel wires or steel strips can be selected to stop weaving. The pressure range of the hose is generally PN0.6 - 32.0Mpa. The maximum is 42.0Mpa
Pneumatic butterfly valve products include oil conveying and suction hose, steam hose, sand blasting hose, acid and alkali conveying and suction hose, food hose, oxygen blowing hose and various special-shaped hose, which are widely used in machinery, chemical industry, petroleum, metallurgy, food and other industries
