1、 Pneumatic pneumatic ball valve pipeline design Pneumatic ball valve is a single turn 90 on-off valve. Under the action of air source pressure, the pneumatic actuator (pneumatic head) drives the piston to move and drives the valve to realize on-off action. The air supply pressure used for pneumatic valves is generally 0.3~0.8MPa, and the following components are generally configured, including filter pressure reducing valve, solenoid valve, limit switch, pneumatic head and other components. According to the action form of the valve in case of failure, pneumatic valves are divided into two categories, single acting and double acting pneumatic ball valves.

3. Steel seal is an important factor to identify the authenticity of valves. For most valve products, the valve body will be printed with brand, words, label and other parameters. No matter whether the font size of the steel seal is large or small, professional steel seal technology will be used. The steel seal is embossed before the valve is overheated, so the font is clear.
