Abstract: In accordance with at least one aspect of this disclosure, a retractable hose reel system includes a reel configured to rotate about a shaft, a fluid driven motor configured to drive the reel, a fluid connector configured to connect to a fluid source to power the fluid motor, and a fluid line connecting between the fluid connector and the fluid motor to supply fluid from the fluid source to the fluid motor to power the fluid motor. A valve is disposed in the fluid line, configured to move between an open position and a closed position, where in the open position the valve allows fluid flow to the fluid motor and in the closed position the valve prevents fluid flow to the fluid motor.
