Operation
1. Plumb up the valve as outlined above in the setup procedures.
2. Regulate the air pressure operating the valve between 60-100 psi.
3. Make sure that the valve is not aimed toward anyone. Cycle the valve several times.
When the valve is cycling, the piston can be heard hitting the micrometer
adjustment and the needle (1){1}[1]<3> can be seen going up and down in the center.
4. Adjust the atomizing air pressure regulator. Air should be felt flowing from the end
of the valve when the valve cycles open. If the valve is not cycling properly, refer to
the Troubleshooting section.
5. When the fluid delivery system is connected to the valve, pressurize the material to
be dispensed.
6. Cycle the valve open to purge. Fluid should begin to spray from the tip of the air cap,
continue cycling the valve until all air is removed from the fluid line and a steady
spray pattern of material can be seen.
7. Adjust the atomizing air pressure to achieve proper spray of material. This pressure
will vary due to the viscosity of the fluid.
