What types of Control Valves have you worked on, and what work did you do?
This question is designed to gauge your technical capability. Be specific with the types of control valves you've worked on (Fisher, Valtek, Honeywell, or other). Think about a specific example where you used a control valve and what work you were doing.
"I have experience working with a Honeywell control valve on a water heater. I like to do my own technical work at home as much as possible. When our water heater wasn't working, I did some troubleshooting online and figured out it was the water heater control valve. I followed the steps in the online manual and replaced it myself. It helps to have a technical background where I've used control valves before to work on tasks at home."
