| The 4560 use a pressure and flow compensated valve block which requires much different setup than the STX closed centre block. I am sure your problems can be rectified by properly setting the cycle time on the 4560.
1) Set the Flow Control Knob 2 turns from completely closed.
2) Adjust the PRV (Pressure Reducing Valve) until you achieve an end-to-end cycle time of 17 seconds.
The PRV valve has the jam nut and 3/16" allen screw.
Reduce the cycle time by turning the PRV clockwise. | |
