Pneumatic control valve, operating principle and application in industry

If you are looking for a solution for your production system, please refer to the pneumatic control valve line – the optimal choice to increase economic efficiency and ensure safety for your production. The following article will help you better understand the structure, operating principles and diverse applications of pneumatic control valves in different industrial processes.

What is a pneumatic control valve?

Pneumatic control valve is an important device in the automation of industrial pipeline systems. For conventional industrial valves, they are operated manually. But for control valves, the valve is opened and closed automatically by compressed air thanks to the control signal.

Common types of pneumatic control valves

Pneumatic control valves are classified based on how they work and what they are used for. Some common types include: globe valves, 3-way valves, ball valves, butterfly valves, and angle valves, each with their own unique applications and features.

	Pneumatic control ball valve Size: DN15 – DN200 Material: Stainless steel 304/ 316 Connection: threaded (BSPT, NPT), or flanged Pressure: PN16/ 40 Maximum temperature: 180°C Origin: Korea
	Pneumatic control butterfly valve Size: DN40 – DN450 Material: Cast iron/ stainless steel Connection: Clamp connection, flange connection Gioăng: PTFE Pressure: PN16 Maximum temperature: 180°C Origin: Korea
	Pneumatic control globe valve Model: AIR-D Size: DN15- DN100 Material: Carbon steel/ Cast iron Connection: Flange PN16/ PN25 Pressure: 0-16bar Maximum temperature: 220°C Origin: ITALY

Operating principle of pneumatic control valve

Pneumatic control valves use compressed air to control the transmission of force and change the position or direction of the valve. Pneumatic actuators and position sensors are integrated to ensure precise operation.

Advantages of pneumatic control valves over electric control valves

Automate the operating process. Flexible in receiving control signals. High performance and precision in control. Reduce time and effort for operating procedures.

Application of pneumatic control valve in industry

Pneumatic control valves are widely used in many fields such as water treatment, food industry, and energy systems. There are many types of pneumatic valves such as butterfly valves, ball valves, globe valves, gate valves and angle valves, each suitable for specific applications in industry and water treatment. Choosing the right one for each application is important to ensure performance and safety.
