Pneumatic pneumatic ball valve can be divided into O-type pneumatic ball valve and V-type pneumatic ball valve. The O-type pneumatic ball valve is of floating structure. The core of the ball valve is precision casting, and the surface is plated with hard chrome. The valve seat is made of reinforced polytetrafluoroethylene material. The flow port is the same as the pipe diameter, with great flow capacity, minimal flow resistance, and no leakage when closed. It is generally used as an on-off valve, especially suitable for high viscosity V-type pneumatic ball valves. It is of fixed structure, and the ball core has a V-shaped notch, It can shear fibrous and granular media. According to different process equipment, pneumatic or electric actuators can be selected to form pneumatic and electropneumatic ball valves respectively. Pneumatic and pneumatic ball valves must be equipped with valve positioners to achieve proportional adjustment, and electropneumatic ball valves must be equipped with electronic electric actuators or servo amplifiers to achieve proportional adjustment. In terms of material, it can be divided into: carbon steel pneumatic ball valve, stainless steel 304 pneumatic ball valve, 316 pneumatic ball valve and copper pneumatic ball valve. According to the pressure, it can be divided into: high-pressure pneumatic ball valve and low-pressure pneumatic ball valve!
