Square pneumatic butterfly valve

The working principle of a square pneumatic butterfly valve is to drive the valve stem through a pneumatic device, causing the valve disc (butterfly plate) to rotate around its axis, thereby achieving the opening and closing of the medium. Specifically, the pneumatic device provides power and drives the valve stem to rotate through the pneumatic actuator, causing the valve disc to rotate accordingly, thereby controlling the flow area of the medium and achieving fluid control.

working process

Pneumatic actuator: The pneumatic actuator receives control signals, adjusts the air source pressure, and drives the valve stem to rotate.

Valve stem rotation: The rotation of the valve stem drives the valve disc (butterfly plate) to rotate. The valve disc rotates between 0 ° and 90 °, with the valve closed at 0 ° and fully open at 90 °.

Medium control: By adjusting the rotation angle of the valve disc, the flow rate and pressure of the medium can be controlled to achieve fluid control.

Application scenarios

Square pneumatic butterfly valves are widely used in various industrial industries, especially in the following scenarios:

Petrochemical industry: used to control media such as crude oil and chemical raw materials.

Food and beverage industry: Due to its characteristics of not being easily contaminated and easy to clean, it is suitable for the production process of food and beverages.

Steel metallurgy industry: able to adapt to high temperature and high pressure environments, used to control high temperature and high pressure media.

Environmental engineering: used for wastewater and exhaust gas treatment to meet the requirements of environmental protection treatment.

Central heating system: used for hot water control and regulation to improve the efficiency of the heating system.
