Product Introduction:

A pneumatic butterfly valve consists of a butterfly valve equipped with a pneumatic actuator. The pneumatic actuator drives the disc to rotate 90 degrees through the air source pressure. According to the working mode, it can be divided into two-position type and intelligent regulating type. That is, it can be used for two-position control to fully open or close the valve, or a valve positioner can be added to the actuator and the corresponding signal can be input to adjust the disc of the pneumatic butterfly valve from 0 to 90 degrees arbitrarily.
