How to connect a third function valve to your hydraulic system

All third function kits use a hydraulic control valve which needs to be connected to a source of consistent hydraulic pressure and flow. This means that the valve can be connected directly the hydraulic pump, or to the power beyond. The D03 & D05 style valves (15 GPM & 25 GPM valves) have a pressurized tank line, allowing you to connect any valves downstream to the tank port. All Z50 (13 GPM) and Z80 (21 GPM) valves have a low pressure tank port, and a separate power beyond port (high pressure/high flow).
