Pneumatic Butterfly Valve Working Principle
Oct 21, 2018

The pneumatic butterfly valve uses the compressed air as the power source to drive the valve stem to control the disc-shaped disc to rotate around the axis. The initial position of the valve is determined according to the actual demand. When the valve is rotated 90&deg from the initial position, it is the end of an action. To the off, or from off to on), and vice versa for another action (from off to on, or from on to off).

The operating speed of the pneumatic butterfly valve is relatively fast, it is not easy to be damaged due to jamming during the operation process, and it is not required to be used by the workers. It can be used not only as a shut-off valve, but also as a valve positioner to adjust the function of the control pipeline medium. Pneumatic butterfly valve actuators are divided into single-acting and double-acting modes, and the double acting is for ventilation and ventilation. Among them, the single-acting actuator has the function of spring reset, which can be automatically turned off or turned on in case of gas break or power failure, and the safety factor is high!
