What is the operating pressure range for spray heads in an irrigation system?

The operating pressure range for spray heads in an irrigation system is typically in the range of 20 to 30 psi. This pressure range is optimal for spray irrigation as it allows for proper atomization of water, creating a fine mist that can effectively cover the target area with uniform distribution. Operating at this pressure ensures that the spray patterns function as designed, preventing issues such as water pooling or insufficient coverage that can occur at lower or higher pressures. Additionally, maintaining the pressure within this range helps to minimize water wastage through evaporation or drift, ensuring the system operates efficiently while conserving water resources.

Understanding this pressure range is crucial for selecting the appropriate spray heads and for troubleshooting system performance, as deviations outside this range can lead to significant problems in irrigation efficiency.
