Non-contact Jet Dispensing

The jet dispensing process using piezoelectric valves offers the possibility to release fluid drops without a dispensing tip. The distance between the dispensing valve and the substrate is much larger and can be in a range of 1mm to 100mm depending on the fluid type, the feed pressure and the required positioning accuracy.

Jet dispensing offers outstanding advantages regarding fluid dispensing speed and cost-effectiveness. Fluid can be applied in volumes as small as 0.5 nanoliters, at continuous speeds up to 500Hz. Because nothing but the material being applied contacts the substrate, there is normally no need for time-consuming Z-axis movement. Additionally, jet dispensing offers improved process control due to the possibility of detecting the released fluid drop with standard sensors.PICO VALVE

We offer several types of piezoelectric dispensing valves for a large range of fluids. We determine the optimal valve type based on your application data and the results of our tests.

General information on typical jet valves and their application range appears below.

PICO® MV-100
Standard valve design with all-purpose properties. The PICO valve MW-100 is best for most medium viscosity and thixotropic fluids, such as grease, oil and most one-component adhesives. Perfect for most UV-curing adhesives and coatings. The PICO Valve can be heated to +100°C.

PICO MV-100-P2
Standard valve design with all-purpose properties. Best for most middle viscous and thixotropic fluids such as grease, oil and most one-component adhesives. Perfect for most UV-curing adhesives and coatings. Valve can be heated up to +100°C.

The 2mm protruding nozzle design allows a reduction of the jet distance and improves positioning accuracy.

PICO MV-200
Standard valve design with all-purpose properties. Valve/fluid can be heated to +200°C. Perfect for many meltable materials, such as wax, thermoplastic and hot melt adhesives.

PICO CV-180-P2
Piezoelectric valve for low viscosity fluids, e. g. water-based fluids or silicone oils. All wetted materials are FDA compliant. Valve is heatable to +180°C.
