What is a Control Valve and How does it Work? We would almost always like to have control over different parameters of the process like temperature, pressure, level, and so on.

To achieve this, obviously, we need a controller like Programmable Logic Controller or PLC for short.

We also need some sensors and transmitters to send data over to PLC. Finally, we need a piece of equipment to carry out the PLC’s commands which usually called “Final Control Element.” A Final Control element can be a pump, a heater, a control valve, and so on.

In this video, we will learn about the control valves, their operation mechanism, and components in an easy-to-understand method.

After this video, you’ll have a great understanding of:

➡ Control valve basics (What are control valve components?)
➡ Most applicable control valves in the industry (such as globe valves)
➡ How Pneumatic Control Valve works
➡ Control valve actuator types
➡ Control valve positioner types
➡ I to P transducers (or I to P converters) and their applications
