Globe Valve
A Globe Valve is a common type of control valve used in plumbing and piping systems. Think of it like a tap or faucet that can precisely control the flow of water or other liquids. Unlike simple on-off valves, globe valves allow for fine-tuning how much liquid flows through pipes. They are important in both residential and commercial plumbing, and knowing how to work with them is a key skill for plumbers. Similar types include gate valves and ball valves, but globe valves are preferred when careful flow control is needed, like in heating systems or industrial settings.

Example Interview Questions
Senior Level Questions
Q: How do you troubleshoot a faulty globe valve in a high-pressure system?
Expected Answer: A senior plumber should explain the inspection process, safety procedures, and systematic approach to diagnosing issues like stem damage, worn packing, or seat problems. They should also discuss when replacement is more cost-effective than repair.
Q: How do you determine the right size globe valve for a system?
Expected Answer: Should discuss factors like flow rate requirements, pressure ratings, pipe size matching, and system specifications. Should mention the importance of checking manufacturer specifications and building codes.
Mid Level Questions
Q: What are the main advantages of using a globe valve over other valve types?
Expected Answer: Should explain how globe valves provide better flow control compared to gate or ball valves, their durability in frequent use situations, and typical applications where they work best.
Q: Describe the proper installation process for a globe valve.
Expected Answer: Should cover proper orientation, flow direction considerations, connection methods (threaded vs flanged), and the importance of proper support and alignment.
Junior Level Questions
Q: What are the basic parts of a globe valve?
Expected Answer: Should identify main components like the body, bonnet, stem, disc, and handle, and explain their basic functions in controlling flow.
Q: What safety measures do you take when working with globe valves?
Expected Answer: Should mention basic safety practices like pressure relief, proper tool usage, and personal protective equipment requirements.
