As a general rule:
The hydraulic system shown above must contain over center valve, control valve and pressure
relief valve for having the winch operated correctly. Failure to use the correct valves may result in
damage to the winch, property, or personal injury.
The relief valve must be set at the winch operating pressure and doest not exceed the rated
pressure. Failure to use the correct pressure and flow may result in damage to the winch, property
or personal injury.
The hydraulic pressure or flow lower than those ratings for the winch may result in a lower line
pull or lower line speed.
The bigger nominal bore hose, the better winch performance.
Keeping cleanliness and accuracy on the hydraulic system installation are essential to have
hydraulic system functioned properly
Pressure and flow loss is increased as hose length increases or hose size decreases.
Pressure and return lines in excess of 3.5 meter ( 11.5” ) should be compensated with an increase
in nominal hose size
Setting range of 70~210 bar and pilot ratio of 4.1:1 for over center valve are recommended.
