The working principle and characteristics of pneumatic butterfly valves

Pneumatic butterfly valves are commonly used automatic control valves. They are driven by pneumatic actuators and can achieve remote control and automatic control. They are widely applied in fields such as petrochemicals, manufacturing, and environmental protection.

I. Working Principle of Pneumatic Butterfly Valve

The working principle of a pneumatic butterfly valve is to convert pneumatic energy into mechanical energy through a pneumatic actuator, driving the valve to open, close and regulate. The interior of a pneumatic actuator includes cylinders, pistons, valves and control elements, among which the cylinder is the most crucial component. It pushes the piston through the effect of air pressure, thereby driving the movement of the valve. The pneumatic butterfly valve is a type of valve that uses a disc as the shut-off component. When the valve is opened or closed, the disc rotates around its axis, thereby achieving the opening, closing and regulation control of the fluid.

Ii. Characteristics of Pneumatic Butterfly Valves

It has a large driving torque and can adapt to the control of large-diameter, high-pressure and heavy-load valves.

2. It has a fast response speed and can achieve high-frequency switching and regulation control.

3. It is easy to operate and can be remotely controlled or automatically controlled, which improves production efficiency and product quality.

4. The disc has a compact structure and low fluid resistance, making it suitable for flow control of high-viscosity and highly corrosive media.

5. It features a simple structure, convenient maintenance, high reliability and a long service life.

Iii. Application of Pneumatic Butterfly Valves

In the petrochemical field, pneumatic butterfly valves can be used for the cut-off and regulation control of equipment such as pipelines, storage tanks and reactors.

2. In the field of production and manufacturing: Pneumatic butterfly valves can be used for the control of fluid control systems, water supply systems, air conditioning systems and other equipment.

3. In the field of environmental protection and governance: Pneumatic butterfly valves can be used for the control of waste gas and wastewater treatment systems.
