Control Valve Maintenance and Troubleshooting

Course Description

This intensive 5-day Course forms part of the Instrument Technicians / Engineers development program and is designed to provide the required underpinning knowledge of Control Valves. It is a primarily classroom based unit covering the aspects of valves, valve actuators and valve accessories. It will also cover the operating principles, applications, terminology and failure modes associated with a variety of different process valves and actuators. Valve and actuator sizing will be covered. Maintenance and troubleshooting methods and techniques are included.

 

Course Objectives

At the end of this training course, participants will understand the use of control valve in closed loop control systems and the valve type characteristics and applications. In addition, participants will be able to explain cavitation and flashing cause /effects and methods to minimize, evaluate and select actuators for specific application, understand valve sizing and the use of the flow coefficient factor and evaluate and select actuators for specific valve applications. This course will also equip participants with understanding of the use of pneumatic, smart positioners and I/P converters; the ability to describe the use of valve accessories limit switches, volume booster and quick exhausts. Participants will also understand the applications for Shutdown / Blowdown and Process Shutdown Valves, be able to understand the principals of valve and actuator sizing to ISA standards and understand the methods and techniques of Maintenance and Troubleshooting.
