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.
Specific Knowledge or Skill Obtained
This course teaches the following specific knowledge and skills:
- The operation of a typical control valve and the purpose of the major component parts
