What is a characteristic of zone valves in irrigation systems?

Zone valves in irrigation systems are designed to control the flow of water to different areas or zones independently. This feature allows for precise management of water distribution according to the needs of each specific zone. For example, one zone may require more water due to its plant type or soil conditions, while another may need less. By being able to operate independently, zone valves enable efficient irrigation scheduling, leading to water conservation and better plant health.

In contrast, if zone valves were all located in a central location, it might complicate access and maintenance. Requiring manual activation could limit the automation and efficiency that modern irrigation systems strive for. Additionally, the operation of zone valves is indeed related to system pressure, as each zone must be adequately pressurized to function properly. Therefore, the independent operation of zone valves is key to the flexibility and effectiveness of an irrigation system.
