Ports:

• IN: Inlet Port
• CF (Controlled Flow): flow coming from this port is pressure compensated and proportional. Flow can vary from closed to fully open depending on the position of the lever.
• EX (Excess Flow): Flow coming from this port is pressure compensated. If lever is set to 0 all flow will exit the valve from this port.

Relief Valve Operation:

• Comes preset at 1500 PSI
• Relief valve can be adjusted anywhere from 500 PSI to 3000 PSI
• Remove acorn nut to adjust pressure
