Which device helps prevent leaking nozzles while inflight?

The functional boom suck back valve is an essential component in aerial application that effectively prevents leaking nozzles during flight. This valve works by creating a vacuum effect that draws the liquid back into the spray system once the pump is turned off or when the aircraft is not actively spraying. This action ensures that any residual liquid in the spray lines is captured within the system rather than leaking out through the nozzles when the flow is stopped.

By utilizing a suck back valve, aerial applicators can minimize chemical exposure to the environment, improve application precision, and reduce the chances of overspray, which can be particularly important in sensitive areas or when treating specific crops. The design and operation of this valve are critical for maintaining the integrity of the application process while in flight, making it a vital tool for anyone involved in aerial spraying operations.
