The PVC clamshell is a revolutionary way to package nozzles. The design also incorporates an identification label which specifies the nozzle dimensions by color. This unique lubeless chain is being tested for use instead of a standard chain. The lubeless chain reduces maintenance time and allows a wider range of acceptable applications for the unit. This valve reduced the time to change adhesive from 5 minutes to less than 1 minute .
Customers are very pleased with the operation of the new valve.
The design could reduce part cost by using an alternative material without changing the part's heat transfer characteristics.
