Principle operation

Step 1

The grease is sent by the pump or the grease gun enters from the inlet of the block upper part. The sent grease passes along the port shown in the dark gray color, reaches the right-hand side of a piston "A", and moves piston "A" leftward. At this time, the grease on the left-hand side of a piston "A" passes along the port shown in the light gray color, and is discharged from the outlet of No. 2.

fig_1

Step 2

f piston "A" carries out a full stroke leftward, as shown to Fig. 2 by the dark gray color, the port which results in surface of a piston "B" will be connected, and the grease from a pump will move a piston "B" leftward through this port. At this time, the grease on the left-hand side of a piston "B" is discharged from the outlet of No. 7 through the port shown in the light gray color.

fig_2

Step 3

Like last time, if piston "B" carries out a full stroke leftward, as shown to Fig. 3 by the dark gray color, the port which results in right-hand side edge of piston "C" will be connect, grease will pass along this port, and a piston "C" will be moved leftward. At this time, the grease on the left-hand side of piston "C" is discharged from a No. 5 outlet through the port shown in the light gray color.

fig_3

Step 4

If piston "C" carries out a full stroke, as shown by the dark gray color among the right figure, the port which results in right-hand side edge of a piston "D" will be connected, and a piston "D" will be moved leftward. At this time, the grease on the left-hand side of a piston "D" is discharged from No. 3 outlet through the port shown in the light gray color.

fig_4

Step 5

This time, as a result of piston''s "D''"'' carrying out a full stroke, as shown by the dark gray color among the figure, the port which results in left-hand side edge of a piston "A" is connected, and a piston "A" is moved rightward. At this time, the grease on the right-hand side of piston "A" which worked as last operation grease is discharged from a No. 1 outlet through the port shown in the light gray color. Grease will be discharged by the same repetition as henceforth in order of the outlet of 8, 6, 4, 2, 7, 5, 3, and 1.

Setting of discharge volume/ Suggestions

Setting of discharge volume

As for each discharge port, 0.2 ml/stroke grease is discharged at the time of a pump operation. If one discharge port is closed, the quantity from the closed port will be added to and discharged by the next discharge port below.

Exsample × : Plugged port will not discharge.

                 1 : Discharge will be four (4) times the normal amount.

             2, 6 : Discharge will be twice the normal amount.

example

Suggestions

1. Use only the specially designed SP fittings for discharge ports of the SP type valve.

2. When you attach the dischagre port Outlet Check Body please be sure to check whether the Clamping Ring is set correctly. Moreover, when you attach SPB plug into the grease dischagre port, please be sure to remove the  Clamping Ring, if present. If a Port Plug is attached with the Clamping Ring. set, the whole valve stops operating.

3. Use proper torque when installing AP & SP Progressive Block specialty adapters.

4. Installation will become difficult if assembly of AP & SP Progressive Blocks is begun with the middle discharge ports. Begin assemble at one end and continue to the other on each side to insure proper and more efficient assembly.

5. Use the correct washer and proper torque when installing AP & SP Progressive Block port plugs.
