Which valve type is recommended for section control in irrigation systems?

The globe valve is recommended for section control in irrigation systems primarily due to its design which allows for precise flow regulation. This type of valve features a spherical body and an internal baffle that enables it to control flow easily by adjusting the position of the disc.

When operating an irrigation system, it's often necessary to manage water flow to different sections effectively, and the globe valve provides this flexibility. The ability to regulate and throttle flow helps maintain uniform water distribution across various zones, making it a suitable choice for applications where precise adjustments are crucial. Additionally, globe valves generally offer better sealing capabilities than gate or drain valves, which are not designed for throttling.

On the other hand, gate valves are typically used for fully open or fully closed operations and do not provide the same level of flow control as globe valves, while drain valves are specifically intended for emptying systems rather than controlling flow to sections. Insert fittings do not pertain to flow control but rather act as connectors in the irrigation piping system. Thus, the globe valve stands out as the ideal option for section control due to its ability to finely adjust flow and maintain consistent irrigation performance.
