Valve operational chart
Step1
Sp series progressive valve The grease pressed through by pump or grease gun comes in though the inlet on the top of block. The incoming grease passes through ports marked with dark color reaches to the right side of piston "A" and moves the piston "A" to the left. The grease on the left side of piston "A" is discharged from outlet 2 through the ports marked with light color
Step2
Sp series progressive valve After piston "A" makes a full stroke to the left, as figure 2 shows, it opens up the port to the right side of the piston "B" which is marked dark color. The grease from the pump traveling through this port moves the piston "B" to the left. At this time, the grease on the leftside of the piston pump "B" is discharged from outlet 7 through the port marked with light color.
Step3
Sp series progressive valve Same as above. After piston "B" makes a full stroke to the left, as figure 3 shows in dark color, it opens up the port on the right side of piston "C". The grease traveling through this port moves the piston "C" to the left. At this time, the grease on the left isde of the piston "C" is discharged through outlet 5 marked with light color.
Step4
Sp series progressive valve After piston "C" makes a full stroke, as the right figure shows in dark color, it opens up the port on the right side of the piston "D" and moves the piston "D" to the left. At this time, the grease on the left side of the piston "D" is discharged through outlet 3 marked with light color.
Step5
Sp series progressive valve Now after piston "D" makes a full stroke, as it shows in the figure in the dark color, it opens up the port on the left side of the piston "A" and makes the grease on the right side of piston "A" discharge from outlet 1 through the port marked with light color. From then, grease is discharged repeatedly following the order of 8, 6, 4, 2, 7, 5, 3 and 1.
Set discharge volume
Example4
Sp series progressive valve
1.  Every SP Block discharge port is marked with number. Do not plug the two farthest discharge ports (left and right) from the inlet. If those two discharge ports are plugged, the whole block will not work.

2. 
When using SP Block as a Master Block (Master Distribution Valve), use connectors with check valve on the discharge ports.

3.  Use special connector on SP Block discharge ports.

4.  When connector is installed on the grease discharge port, make sure clamping ring is installed. When installing the plug on the dischaege ports, make sure to remove the clamping ring. The whole block will not work if plugged with clamping ring.

5.  To make sure installing the clamping ring firmly in place, tighten firmly the outlet body or compression nut.

6.  When screwing the connector into the discharge ports, install in the order of either from top or bottom. If starting from the middle or skipping one to next one, it becomes difficult to use the wrench due to limited space.

7.  When screwing the plug into the grease discharge port, make sure to tighten firmly. Do not use the used copper washer. Replace it with a new one.
