As an important fluid control device, pneumatic flanged butterfly valve is widely used in chemical,
petroleum, metallurgy and other fields.
The pneumatic flanged butterfly valve is composed of a body, a disc, a stem, a seat and a driving device.
Its most notable feature is the unique shape of the valve disc, similar to the shape of a butterfly, hence
the name butterfly valve.
The disc of the butterfly valve can be freely rotated in the pipe, and the flow of the fluid can be adjusted
by changing the rotation Angle.
In addition, the flange butterfly valve also has the characteristics of simple structure, light weight, easy
installation, etc., which makes it widely used in the industrial field.
The working principle of the pneumatic flanged butterfly valve can be simply divided into two steps:
opening and closing.
When the valve is opened, the drive rotates the valve to an Angle through the air pressure, so that the
fluid can pass smoothly.
When the valve is closed, the drive rotates the valve perpendicular to the pipe, preventing the passage
of fluid.
