Providing high flow rates and optimal reliability,

Download our catalog

Discover the new generation of high-flow 3/2 solenoid-operated valves for IS machines, designed for the glass industry.

The features are as follows:

Exceptionally high flow rates, specifically designed for glass blowing applications:

- 67 series : 20000 Nl/min (Cv 20.0)
- 68 series: 31000 Nl/min (Cv 31.0)

Innovative technical design: fewer components for enhanced reliability.
Designed to operate in the harshest environments.
High resistance to contaminants – unaffected by pressure fluctuations.
Fast and precise switching with an extremely high level of repeatability.
High-temperature modification for resistance up to 80°C (176°F) for the valve and its pilot.
Reduced machine downtime – increased productivity.
High reliability – maximizes your machine’s efficiency throughout its operation.
