  • Page 23 The maximum amount of weight that can be lifted is limited by the pressure relief valve. The settings must be determined with a pressure gauge. The D6071-57-THIN requires 1650 psi to lift a 400 lb load. Place a pressure gauge after the hand valve and run the actuator until it stops, continue activating the handle and note the pressure on the gauge.

  • Page 25 With the system off and depressurized, find the pressure line that feeds the packer valve and disconnect it. Connect this pressure line to the “IN” port of the Perkins diverter valve. Connect the “OUT” port of the diverter valve back to the packer control valve where the pressure line originally was.
  • Page 26 The Perkins Diverter Valve Ordinarily, the diverter valve’s port “P” will feed the lifter. But, if you have two lifters, then you will use the Perkins Double Diverter Valve. It’s the same valve, except port “P” is plugged, and a 50/50 splitter valve is mounted on top.
  • Page 27 Tapping into the Tank Line There are two ways to run the oil back to tank. Perkins does not suggest allowing the return oil to get pushed back into the packer control valve, because this generates back pressure and heat.
  • Page 28 Adjusting the Perkins Hydraulics Adjusting the Speed Single Diverter: D63237s Double Diverter: D63411s This valve’s adjustment controls the flow going to the lifter. The flow controls the speed of the lifter. A typical 27k rotary lifter requires 3.5 gpm to achieve a 6-8 second cycle time.
  • Page 29 Raise the lifter until it stops and continue to pull the handle. Note the pressure on the gauge and adjust the screw accordingly. Note: The setting for the D6071-57-THIN is approximately When the pressure is correct, 1700 psi to lift 400 lbs. retighten the locking nut.
