5 Initial Start-up
5.1 Mounting and Installation
IMPORTANT
We recommend adding a maintenance unit to the control air.
5.2 Adjusting the Incomplete Device
IMPORTANT
Check if the air pressure for the control air is at approx. 6 bar. This will guarantee an
optimum function of the valves.
The supply material pressure to the valve should not rise above 200 bar. Check the
pressure ratio of the supply pump. A pressure reducing valve will help you control the
supply pressure easily (a pressure reduction valve is an advantage but not mandatory
as long 200 bar will not be exceeded).
IMPORTANT
All dosing valves will be thoroughly checked before leaving our factory. It is therefore
possible that some residues of the test medium remain in the valve.
1) Make sure that the lubricant feed hose is filled with lubricant and all air is removed. Then connect
feed hose and air connectors according to drawing.
2) For first operation, set valve to maximum dosage (i.e. turn adjustment screw to outmost position.
3) If the adjustment screw cannot be turned, change position of change-over-valve. The adjustment
screw should now be unlocked.
4) Execute a first shot of lubricant. Then set the adjustment screw to the desired grease quantity.
5) Keep the distance short between the dosing valve and the greasing point. This allows for improved
metering precision and repeatability.
6) The cycle time depends on the viscosity of the lubricant, as well as on the lubricant feed pressure.
