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.

Pneumatic ventilation butterfly valve Pneumatic ventilation butterfly valve is a kind of ventilation butterfly valve. It is mainly used in sintering and smelting systems of metallurgical industry or ventilation and dust removal pipelines of building materials, energy, chemical industry, environmental protection and other industries. It is a safe and reliable regulating and isolating device
