Control Valves & Actuators
How control valves and their actuators turn a controller's signal into real process change: body styles, fail-safe action, positioners, flow characteristics, sizing, and the diagnostics that keep the final control element healthy. For instrument technicians, operators and engineers in process plants.

Qué aprenderá
- Explain the role of the control valve as the final control element in a control loop
- Compare globe, ball and butterfly valve bodies and match each to a typical service
- Describe actuator types and justify a fail-open or fail-closed choice from the process safety consequence
- Explain what positioners and I/P converters do and how the inherent flow characteristic affects control
- Recognise the symptoms of oversizing, cavitation, flashing and noise, and their impact on control quality
- Bench-stroke a valve safely and interpret basic diagnostic results such as stroke tests and valve signatures
