Proper sizing of irrigation valves is crucial for pressure efficiency, as it directly impacts the system's ability to deliver water at the optimal pressure needed for effective irrigation. When valves are sized appropriately, they ensure that the water flows smoothly through the system without causing excessive pressure loss or surges, which can lead to uneven water distribution across the landscape. This is particularly important for maintaining healthy plant growth and preventing water waste.

Additionally, correctly sized valves help avoid issues such as valve chatter and potential damage to the system due to pressure fluctuations. By ensuring that the valve size matches the flow requirements of the irrigation system, operators can maintain better control over water distribution, leading to more efficient irrigation practices overall.
