Introduction to Control Valves
In Introduction to Control Valves, you'll learn ...
- Control valve terminology, fail close and open systems, and valve body types and plug styles
- Actuator types and how they operate
- The purpose of valve positioners and the various types of positioners
Overview
Control valves are widely used in industry to manipulate gas, steam, and liquids. Control valves keep the process variables (pressure, temperature, level, flow, etc.) as close as possible to the desired set points. Their selection and design should be a way to compensate for the disturbance of the load and regulate these variables.
In this course, we will cover control valve terminology, fail close and open systems, and valve body types and plug styles. Because an important part of control valves are actuators, we will also cover a wide range of actuators. Finally, we will cover valve positioners and their types, especially newly developed electro-pneumatic and digital positioners.
