Low melt strength materials require very fast control response time to maintain stability, particularly during startup and order changes. The new PA340 proportional valve has been recently introduced as the next generation proportional valve. Customers who have tested the valve have found an improvement in layflat control, and the ability to increase production rate.

The new proportional valve is different from the familiar cylindrical valves that have been used on IS-IBC1 systems for the past 14 years. The new valve is smaller, 30% faster, eliminates the 20 micron inlet filter, is quieter, cooler, and has three times the service life of our previous valves.
