Theory of Operation
The SJ100 valve is a non-contact dispense valve that applies small shots of fluid as
individual dots or in rapid succession. Only three components come in contact with
fluid: the fluid body, needle, and nozzle. With this design you can dispense at speeds up
to 140Hz. The SJ100 is designed to dispense coatings and other low viscosity materials
with very fine control.
Personal Protective Equipment
Operators must use eye protection because material contents are under pressure.
Always wear gloves when handling materials and solvents. Refer to MSDS sheets on the
material being dispensed for other precautions.
Waste Disposal
Dispose of all used parts and materials in accordance with local laws and regulations.

Install Jet nozzle
1. Use Portal to set the jet valve to “Open” or set the air pressure to 0 psi.
2. Turn the nozzle retaining cap counterclockwise to remove it.
Figure 2: Remove the Retaining Cap
3. Install the jetting nozzle.

5. Use Portal to set the jet valve to “Close” or increase the jet pressure.
Set the Valve Stroke
Do the procedure below to adjust the micrometer and set the valve stroke as necessary.
1. Turn the micrometer counterclockwise to increase the valve stroke.
2. Turn the micrometer clockwise to decrease the valve stroke.
NOTE: A larger valve stroke will result in larger dot sizes. Nominal valve stroke
is recommended at 0.01” but will be material and application dependent.
