Course Details
Control valves are the workhorses of facilities. They continually function to ensure systems work as intended.
The control valve is the part of the control loop that not only requires integration with modern data collection methods. It also involves mechanical features, as well as occupational health and safety issues not associated with other parts of the control loop (such as noise).
A correctly specified, engineered, designed, installed, and maintained control valve can be one of the most profitable investments a facility can have. However, a control valve that “does not work well” can increase the risk of injury and disruption to your system. Often the benefits of modern SCADA systems can be lost with inappropriate or minimal attention to the control valves.
This course will help you understand what happens inside a control valve from a basic fluid mechanics point of view. This includes appreciating the difference between cavitation and flashing and realizing the difference between controlled and choked flow. You will also learn to choose between different characteristics on offer, understand the advantages and disadvantages of different seat leakage rates, and understand the failure modes for control valves and demonstrate new approaches to troubleshooting.
It will also cover how to recognize severe service applications and have an appreciation for the methods of tackling the problems associated with such applications. Plus, it will teach you to do simple calculations to determine control valve values, and identify the different types of control valves commonly in use and understand the relative advantages of each.
You will also learn to use a computer sizing program to assist with the selection of control valves, select materials for bodies, trims, packing boxes, and gaskets, and size actuators for linear and rotary applications and know the relative advantages of pneumatic, hydraulic and electric types.
Case studies will illustrate the key concepts through examples of real-world working control valves.
The course is composed of 12 modules, covering the essentials of control valves and actuators, to better place the user to fully realize the full potential and benefit of any control system.
