Correspondence Course

The Course

Working with Valves is a 10 module correspondence course that is designed to be completed in about 50 hours over a six month period.

It starts with the basics of what a valve is and how to select a suitable type of valve for an application and continues up on to control valves and actuators.

There are written tests and assignments at the end of each module and a final examination at the end - with a 75% pass mark.
