What part of the nozzle contains the water control valve?

The water control valve, which regulates the flow of water through the nozzle, is located in the shut-off portion of the nozzle. This feature allows firefighters to control the delivery of water effectively, enabling them to start and stop the water flow as needed during firefighting operations. The shut-off mechanism is crucial for managing water pressure and conserving water when it is not needed, such as during repositioning or when a fire is contained.

The flow control component, while also important, specifically influences the rate and pattern of the water as it exits the nozzle rather than controlling the intake of water itself. The nozzle body refers to the main structure of the nozzle that houses various components, but it does not contain the actual control mechanism for the water flow. The tip of the nozzle is where the water exits, and while it plays a role in determining the spray pattern, it does not include the control valve.
