Valves, Piping & Flow Control Basics

A practical overview of common valve and piping functions in water and wastewater facilities. The course explains isolation, throttling, check-valve function, pressure and flow control, safe valve operation, flow-path verification, pressure-surge/water-hammer awareness, and basic operator troubleshooting when a valve or piping condition appears abnormal.

What you’ll learn

• Identify the general purpose of common isolation, control, and check valves.
• Explain why valve position and piping configuration affect flow and pressure.
• Recognize operating practices that can reduce pressure surges and water hammer.
• Use a simple flow-path check to investigate unexpected flow or pressure.
• Record and escalate abnormal valve or piping conditions without performing unauthorized maintenance.
