Advanjet Jet Valves
Advanjet Jet Valves is Graco's complete line of microdispensing, non-contact jet valves designed to deliver high process accuracy and application flexibility in microdispensing dots, lines and complex shapes. What makes our technology different from other non-contact jets is the incredible simplicity of its patented design.
Easy to Clean. Outstanding Performance.
- Minimal wear parts and maintenance – no fluid seals to clean or replace
- Precision dispense over any surface, including uneven, irregularly shaped, or hard-to-reach surfaces
- Superior pattern capability to create microdrops, lines or complex shapes
- Up to 300 drops/sec with outstanding repeatability
- Low to medium viscosities, handling materials up to 400,000 centipoise

Incredibly Easy to Clean
With only two parts contact the fluid and a disposable feed tube, cleaning the jet valve takes only minutes. Conventional jets can have as many as eight parts requiring cleaning. There is no need to remove the jet from the robot. A diaphragm and nozzle plate install immediately without the need to carefully calibrate the jet saving valuable production time. And, no intricate, expensive cartridge to disassemble.
Speed – Continuous jetting at 300Hz will meet the demands of high-volume production.
Repeatability – Tested in the most challenging environments, the diaphragm jet has proven to generate consistently repeatable, high-quality drops and lines.
Capability – Achieve a high process capability and wide process window by adjusting the jet velocity to reduce accumulation of “stringy” fluids.
Reliability – The Diaphragm Jet is designed to last and last. And when it’s time for maintenance, parts can be quickly replaced at your factory.
Low Running Cost
The simplicity of the Diaphragm Jet, with only two internal moving parts, delivers one of the industry’s lowest running cost per million cycles of the jet. Unlike piezo jets with costly replacement parts that require the jet to be sent out for repair, Advanjet Diaphragm Jets can be completely maintained and repaired in your factory. The two moving pneumatic parts, the solenoid, and cylinder have been extensively tested and provide reliable performance for up to 500M cycles with a fraction of the cost of a piezo jet actuator.

The diaphragm is the heart of jetting technology. Diaphragms are available in three different materials to provide high chemical resistance and long service life. Contact our application experts for specific recommendations on which diaphragm is best for your application.
Available in FKM, Silicone, and FFKM in 1.6mm or 3.0mm.
Standard Flat Nozzles
Graco Advanjet nozzle sizes range from 50-700μm and are offered in tungsten carbide or high wear-resistant ceramic. Each single-piece nozzle has been custom designed and precision manufactured to provide the repeatability and performance you expect from Graco.
Extended Tip Nozzles
Many applications require jetting in tight spaces, vias, or cavities. Our nozzles with extended tips allow you to get close to specific targets or around obstacles. Graco offers both a 3 mm, 6 mm and a 10mm version in several different designs to optimize jetting of certain materials.
The design of Graco's Advanjet syringe brackets allow you to easily change out the material amount being used on the jet valves, giving you greater flexibility in your manufacturing process. Syringe brackets are bolted on to the jet valve and are offered in a variety of sizes ranging from 5 cc to 6 oz, as well as having options available for bulk feeding.
