With working pressure up to 16 bar, the type 670 can be easily installed between standardised flanges according to DIN EN 1092-1, making it ideal for both new installations and upgrades to existing systems, even in confined spaces.
Even at larger nominal diameters, the type 670 maintains service pressures up to 16 bar (or higher, upon request), ensuring reliability and operational safety.
The standard version is equipped with borosilicate glass 3.3, suitable for operating temperatures up to 280 °C.
This material offers excellent thermal and chemical resistance, ensuring long durability and constant transparency.
Sealing is achieved with flat gaskets selected according to process requirements.
This variety allows adjustment of the seal to the medium, temperature and working pressure, ensuring maximum compatibility and tightness.
If your process requires even higher pressures whilst maintaining 360° panoramic vision, we recommend the type 671 model, specifically developed for high-pressure applications.
