The pneumatic butterfly valve is controlled with aluminum piston by the compressed air. The piston controls the valve disc to work with 90degree so the valve open or close. The pneumatic actuator can be dis-assembly and maintenance. The torque of the pneumatic actuator is big , it is easy to install and operate.
