Leary Launches Sempre-i Cold Glue Valve

W.H. Leary Co., Inc., Tinley Park, Illinois, a manufacturer of quality assurance, glue application and mechanical solutions for the packaging industry, has introduced the Sempre-i cold glue valve, an electronically powered valve offering the highest range of glue viscosity while continuing to deliver precise ±1 mm accuracy. At only 19.8 mm wide, the slim profile makes it the ideal choice for all gluing needs.

Leary’s CleanStart module simplifies the valve’s maintenance and increases plant’s productivity. A nozzle cover is automatically activated when product is halted. This prevents the adhesive from drying on the tip, minimizes recurrent cleaning due to machine stops and improves operator safety. When carton production begins, the nozzle cover is removed and quick production can begin.

The unit’s Predictive Maintenance Intelligence allows users to receive information on when to perform maintenance, ensuring the highest levels of usability and unparalleled longevity of 1 billion cycles. The Sempre-i stores detailed cycle information that is easily accessible from the Monet operator screen. Alerts with customizable set points appear as pop-up windows, offering accurate and timely warnings. When used in conjunction with the CXU-110 Pump & GRU, which also uses Predictive Maintenance Intelligence, users can ensure the optimum overall effectiveness of all glue application components.

Operator safety also is ensured by the location of the optional valve purge button which is positioned on the cable, approx. 23 inches (60 cm) away from the gluer’s moving parts. Quickly and efficiently maintain valve performance, decreasing gluing start-up time.

The Sempre-i’s features include:

  • Slim 19.8 mm wide valve body profile
  • Glue viscosity range 0.3 to 4 Pas (300 to 4,000 cps)
  • 1 billion cycle durability rating
  • Optimized flow for reduced stress on the adhesive
  • Inline purge button on cable for improved operator safety
  • Integrated Valve ID chip for Predictive Maintenance Intelligence
  • Built-in LED for simplified diagnostics
  • Precise micro adjustment of adhesive quantity
