pneumatic butterfly valve

Pneumatic butterfly valve is an industrial valve that uses compressed air to drive the actuator and adjusts the opening and closing of pipeline media or flow rate through the rotation of the butterfly plate. It has a simple structure and flexible operation, and is widely used in fields such as chemical engineering, petroleum, natural gas, water treatment, electricity, and food.

1、 Structural composition

Valve body: usually a circular channel, the material is selected according to the characteristics of the medium.

Butterfly plate: a circular or elliptical plate that controls the flow of medium through rotation, and the material needs to be corrosion-resistant and wear-resistant.

Pneumatic actuator: the core driving component, divided into two types: single acting and double acting.

Attachments: including solenoid valves, limit switches, positioners, filter pressure reducing valves, etc., used to achieve automation control.
