Installation of Unbalanced Valve
If the system was ordered as an Unbalanced System, the kit is installed at the factory. The unbalanced valve accessory is a pilot operated bleed valve. It is intended for use when the steering cylinder fitted to the vessel is of the unbalanced type. In use the bleed valve equalizes the amount of hydraulic oil that is returned to the tank from the low pressure side of the cylinder with the amount of oil that is being pumped to the high pressure side.

Unbalanced Valve adjustment and calibration:
To check or reset the setting of the valve. To check the setting, compare the amount of brass screw extending outside the valve body on both sides of the valve, (See Fig 1) if this is equal and the shoulder of both brass screws
Do not unscrew the brass screws more than the specified amount as permanent damage will be caused to the housing. Also do not operate the system with the brass screws fully tightened as this will cause flow restrictions and therefore draw more electrical current and may damage components.
