Creating Fast, Accurate Valves for Production Lines

A manufacturer was experiencing increased maintenance costs and downtime due to unreliable valves on their product packaging equipment. TLX Technologies designed a high-speed, high temperature solenoid valve with fast response and high repeatability.

Customer Problem

The pneumatic valves installed in consumer product packaging equipment apply adhesives to product packages (such as gluing the flaps on cereal boxes, etc.). A manufacturer was experiencing reliability problems with these valves. This resulted in additional maintenance costs and increased production downtime. The manufacturer needed a reliable solution that would operate at high temperatures, consistently deliver the same shot size (amount of adhesive per cycle), and have a long life cycle.

The TLX Solution

TLX Technologies designed a solenoid valve with fast response and accurate shot size. To improve the solenoid’s response time, force (in the form of power) was increased, and stroke was shortened. These properties, coupled with solenoid magnets, helped reduce the response time to .2 ms while maintaining a change in response that was consistently less than 1.1 %. In addition, the solenoid valve was able to continuously operate in temperatures as high as 480°F.
