Pneumatic Control Valve: Features and Applications
- Válvula DELCO
Pneumatic control valve is now a common valve in the pipeline process, it uses compressed air to regulate the flow of fluids in industrial processes, the following by Válvula DELCO to introduce the main features and applications of pneumatic control valve.
Pneumatic control valve working principle
Pneumatic control valve is the use of compressed air as a driving force, through the cylinder actuator and electrical accessories such as electric valve controller, converter, solenoid valve to control the valve. It changes the flow area of the medium by adjusting the valve stem and seat to realize on-off or proportional adjustment. This kind of valve receives 4-20 mA analog signal and automatically adjusts the degree of opening and closing of the valve, so as to automatically adjust the temperature, pressure and flow of the medium and keep it within the range of the set value. By setting the target value through the instrument, the pneumatic adjustment valve can convert the mechanical energy into corresponding data to realize the precise adjustment of the valve.
Main features of pneumatic control valve
- Has a large rated flow coefficient, suitable for use in regulating the needs of high flow media in chemical plants.
- It can realize precise control under a wide range of process conditions, with a wide range of adjustment.
- Excellent sealing performance ensures that the medium does not leak, improving the safety and stability of the system.
- Adopting double-bearing structure, small starting torque, high sensitivity, able to respond quickly to the control signal.
- Compact structure, small volume, easy to install, can be placed vertically or horizontally to save space.
- Suitable for controlling a variety of media such as gas, steam, liquid, etc. It is widely used in various production processes in chemical plants.
Application of Pneumatic Control Valve
Pneumatic control valve is a kind of valve that uses pneumatic pressure to control the position of the valve, so as to regulate the fluid flow, pressure and temperature. Pneumatic control valves are widely used in industrial process control:
- Steam control: used in steam piping to regulate steam flow and pressure and to control the temperature of the heating system.
- Petrochemical industry: used in oil and gas processing to control fluid flow and pressure and manage the petrochemical production process.
- Chemical industry: used in various chemical reactions, controlling reactant flow and pressure, regulating the chemical reaction process.
- Food industry: used in food production process, regulating various fluid flow and pressure, controlling food production process.
Conclusão
Pneumatic control valves are crucial in industrial operations. Their exceptional regulation capabilities, responsiveness, and dependability establish them as vital control instruments. By precisely managing the flow of diverse substances, these valves not only enhance production efficiency but also ensure the safety and stability of the production process.
