3.3 Functional Description
The pneumatic part of the dosing valve is controlled by a pneumatic 5/2-way valve which is integrated in the handle. Pulling the trigger initiates the grease dosing. The dosing pressure is depending on the pressure in the grease (medium). The air and grease chambers are separated. In order to obtain a high quality and precision of repeating during the actual dosing, the whole cycle has to be completed. In other words, the control piston has to move from the initial position to the dosing position and back into the initial position. .
3.4 Versions
9741970.00 Standard Version
9741970.02 Magnetic Tape at air piston as front part for proximity switch
9741970.03 Initiator for controlling the dosing piston. This special construction increases the process safety. The initiator will send an electric signal once the cycle has been completed, i.e. when the grease has been released. For a process-safe function of the initiator, the smallest selected dosing amount has to be approx. 10% larger then minimum quantity indicated on the valve. When dosing in the lower limit area, we recommend using the next small valve!
9741970.04 Magnetic Tape at air piston and proximity switch at valve. The special construction increases the process safety. The proximity switch will send an electric signal once the cycle has been completed; air piston in the initial position.
CAUTION
For a process-safe function of the initiator, the smallest selected dosing amount has to be approx. 10% larger then minimum quantity indicated on the valve.

4 Commissioning
4.1 Mounting and Installation
IMPORTANT
We recommend a front-end maintenance unit for the control air.
4.2 Adjusting the Incomplete Device
IMPORTANT
Make sure that the air pressure for the control air is at approx. 6 bar. This guarantees an optimum function of the valves. The material inlet pressure should not rise above 200 bar. Check also the pressure ratio of the feeder pump. A pressure reduction valve will help you to easily control the supply pressure (a pressure reduction valve is an advantage but not mandatory, if pressure stays below 200 bar).
IMPORTANT
All dosing valves will be checked at our factory before delivery. It may therefore hap­pen that some residues from the test media remain in the valve.
1) Fill lubricant supply hoses with lubricant before connecting a dosing valve (ventilating). Then connect supply hoses and control air according to layout.
2) Set maximum dosing amount (turn adjusting sleeve to the far outside) when first starting the device.
3) If adjusting sleeve cannot be turned, operate rerouting valve. You can now operate the adjusting sleeve.
4) After the first release of lubricant, the desired dosing quantity can be set through the adjusting sleeve.
5) Keep the distance between dosing valve and greasing area as little as possible. This will increase the precision for dosing and repetition.
6) The possible cycle time depends on the viscosity of the lubricant and the material pressure.
7) The dosing valves can be fastened with 2 M6 screws.
8) The dosing quantity is continuously variable through the dosing screw.
9) Please note that there are 2 switching points per magnetic field when installing the dosing sensors (optional).
