Jet™ Series Glue Application Valves

Jet200™ and Jet205™

Jet200 Glue Application ValveThe Jet200™ and Jet205™ are non-contact glue valves capable of handling a wide range of emulsion adhesive viscosities. These valves are ideal for applications where higher viscosity adhesives and higher pressures are required. The Jet200™ and Jet205™ valves can be fitted with high, medium or standard pressure systems. Each incorporates multi-point pressure control, back pressure relief and low speed spotting, ensuring accurate volume control over the machines speed range.

These Jet™ valves have features designed to reduce set-up times and maintenance:

Water flushing option to improve system start-ups and reduce maintenance
Trigger (photocell) and glue detection sensor can be mounted on the valve
Versatile bracketry and carton guides

Quantum™ High Speed Glue Valves

Leary's Quantum™ cold glue valves use a micro-adjust stroke that delivers up to a 1mm gluing accuracy when using extrusion grade glue. These valves are adaptable enough to be used with high, medium, or standard pressure systems. The easily-adjustable mounting hardware and slim 22.5mm valve body profile make it the ideal choice for most machines.

The two piece nozzle not only makes cleaning and changeovers simple, its 45mm long nozzle also gives the flexibility to glue in even the tightest of spaces.

Choose the valve that best ensures a perfect glue application solution for your cartons. Quantum™ Gold is optimal for specialty applications with extremely complex gluing patterns at high speeds, and where higher power consumption is not an issue. For most other applications, Quantum™ Platinum is the preferred valve.
