1. A retractable hose reel system, comprising:
a reel configured to rotate about a shaft to wind a hose around the reel;
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 supply fluid to the hose;
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; and
a pressure reducing valve disposed in the fluid line upstream of the fluid motor configured to reduce a pressure of the fluid in the fluid line at the fluid motor;
a valve disposed in the fluid line configured to move between an open position and a closed position, wherein in the open position the valve allows fluid flow to the fluid motor, and wherein the closed position the valve prevents fluid flow to the fluid motor;
a lubrication port disposed in the fluid line downstream of the pressure reducing valve configured to provide lubricating fluid to one or more of the valve and/or the fluid motor.
