That depends on the type of fluid you are dispensing. If you are dispensing a particle-filled material, partial clogging in the dispensing tip could cause the variations.

One of the most common factors to consider is your plant air supply. If you have fluctuations in the air-line going into the dispenser, you will almost certainly get variations in your deposit size. Make sure you have a in-line filter regulator between your plant air supply and the dispenser. If you do have plant air fluctuations, you should set the filter regulator approximately 5 to 10 psi lower than your lowest plant air fluctuation point.

Yes, we have both an aseptic dispense valve and spray valve that can be autoclaved, cleaned-in-place or steamed-in-place.  The aseptic dispense valve is used for making dots, stripes, or small volume fills of fluids. The aseptic spray valve is used for spray coating small areas with inner diameters 1/8 in. and larger. Both valves are primarily used on automated machines.
