1. Air supply:

In pneumatic systems, the air source is usually compressed air, which is stored in compressed air tanks or air supply equipment. This air source will be delivered to the pneumatic air control valve through pipelines or pipelines, and become the energy source of the actuator. The supply and stability of the air source are critical to the proper operation of the pneumatic system.

2. Valve body and actuator:

Pneumatic pneumatic control valves are usually composed of two parts: the valve body and the actuator. A valve body is a precision engineered device that contains valves and passages that control the flow of gas. The actuator is a key component that moves based on signals from the automated control system to control the opening or closing of the valve.

3. Control signal:

The control signal can be electrical or pneumatic, depending on the design and application of the pneumatic system. Typically, control signals are generated by automated control systems, which may include inputs from sensors, computers, or operators. These signals will control the state of the valve, indicating whether the valve is open or closed.

4. Pneumatic principle:

The core working principle of pneumatic pneumatic control valve is aerodynamics. When the control signal reaches the actuator, it causes the actuator to move. This movement is usually linear and is achieved by a piston or rod. The movement of the piston changes the position of the valve, which changes the path through which the gas flows.

5. Gas flow control:

As the position of the valve changes, the shape and size of the gas flow path also changes. This results in a change in the flow rate and flow of the gas, enabling automatic control. By precisely controlling the movement of the actuator, high-precision flow control can be achieved. This is important in a variety of applications, such as chemical processes where gas flow in reactors needs to be tightly controlled to ensure product quality and production efficiency.

6. Application fields:

Pneumatic air-operated valves are widely used in various automation systems and industrial applications. They are used to control the flow of liquids or gases to regulate pressure, temperature, level and other parameters to meet the needs of automated systems. Pneumatic air-operated valves can be found in manufacturing, automotive industry, food and beverage processing, medical equipment manufacturing, oil and gas industry, etc.
