Valves are the heart of an irrigation system. To simplify valve installation and maintenance and ensure long-lasting system performance, it’s important to understand how these components work.

In this video, we’ll identify the different components of a valve, including the parts visible on the outside as well as those on the inside. We’ll also show you how water travels through a valve and explain the forces that cause a valve to open and close.
