Operating Instructions, Form No. 102639, Back sheet 1 of 1
1. Assemble the return tube (#200609) and the return port pressure control system (#'s 21278-20, 18841 & 12891-1)
to the valve. Mount the valve to the pump. NOTE: The return port pressure control system is factory set at
1900/2200 PSI. Check stressing tool return for maximum pressure setting and adjust appropriately before
mounting the valve. (If the valve is remotely mounted on a subplate, such as Power Team #9510, the return tube
and the retract port pressure control cannot be used. To achieve the return port pressure control an external
regulator or relief system, such as Power Team #9623 or 9633, must be incorporated into the return system.)
2. Connect a hose from the stress port on the valve to the stress port on the jack.
3. Connect a hose from the return port on the valve to the return port on the jack.
4. Connect a hose from the seat port on the valve to the seat port on the jack.
1. With both valve handles in the center position, start the
pump. Insert the cable into the stressing tool.
2. Shift valve "A" into the stress position. The cylinder ex-
tends, stressing the cable.
NOTE: The pump pressure controls the force exerted by
the cylinder when the valve is in the stress position.
3. When the desired tension in the cable has been reached,
shift valve "A" to the valve "B" position. Shift valve "B" to
the seat position. The cylinder is pressurized to the
seating pressure controlled by the seating relief valve
(3900 PSI).
4. Leave valve "A" in the valve "B" position. Shift valve "B" to
the return position. The cylinder returns and is pressurized
to a maximum of 2200 PSI. The stress and seat ports are
open to tank.
5. After the cylinder has been fully retracted, shift both valves
to the center position.
