Pneumatic Control Valves Introduction: Features and Role
- Клапан DELCO
In the industrial control system, pneumatic control valve plays an important role. It can not only accurately control the flow of various media, but also ensure the stability and safety of the production process. So what role does pneumatic control valve play in chemical plants? The following Клапан DELCO will share in detail.
Pneumatic control valve working principle
A pneumatic control valve consists of a pneumatic actuator and a control valve. It operates using compressed air, where the cylinder acts as the driving force. With the help of components like electrical valve positioners, converters, solenoid valves, and holding valves, the valve can be controlled to switch or adjust proportionally. It receives signals from industrial automation control systems to regulate pipeline mediums such as flow, pressure, and temperature.
Main features of pneumatic control valve
- Large flow coefficient: pneumatic control valve has a large rated flow coefficient, can adapt to the chemical plant in the high-flow media regulation needs.
- Adjustable ratio: pneumatic control valve in a wide range of process conditions.
- Good sealing effect: excellent sealing performance ensures that the medium will not leak, improving the safety and stability of the system.
- Sensitive adjustment performance: pneumatic control valve adopts double bearing structure, small starting torque, extremely high sensitivity and sensing speed, and can respond quickly to the control signal.
- Small volume, easy to install: pneumatic control valve has a compact structure, small volume, can be installed vertically, saving the installation space.
- Wide range of applicable media: pneumatic control valves are suitable for controlling a variety of media such as gas, steam, liquid, etc. They are widely used in various production processes in chemical plants.
Pneumatic control valve in the chemical plant applications
- In the process of chemical reaction, pneumatic control valve can precisely control the flow of reactants to ensure the stability of reaction conditions.
- By controlling the flow of steam or cooling water, pneumatic control valves can effectively regulate the temperature of the heat exchanger to ensure the stability of the production process.
- In the process of material conveying, pneumatic control valve can control the flow of liquid or gas material to ensure the smooth conveying process.
- Pneumatic control valves can be used to control the pressure of the system and protect the safety of equipment and pipelines.
