With working pressure up to 16 bar<\/strong>, the type 670<\/strong> can be easily installed between standardised flanges according to DIN EN 1092-1<\/strong>, making it ideal for both new installations<\/strong> and upgrades to existing systems<\/strong>, even in confined spaces<\/strong>.<\/p>\n

Even at larger nominal diameters<\/strong>, the type 670 maintains service pressures up to 16 bar<\/strong> (or higher, upon request), ensuring reliability and operational safety<\/strong>.<\/p>\n

The standard version is equipped with borosilicate glass 3.3<\/strong>, suitable for operating temperatures up to 280 \u00b0C<\/strong>.
This material offers excellent thermal and chemical resistance<\/strong>, ensuring long durability<\/strong> and constant transparency<\/strong>.<\/p>\n

Sealing is achieved with flat gaskets<\/strong> selected according to process requirements.
This variety allows adjustment of the seal to the medium, temperature and working pressure<\/strong>, ensuring maximum compatibility and tightness<\/strong>.<\/p>\n

If your process requires even higher pressures<\/strong> whilst maintaining 360\u00b0 panoramic vision<\/strong>, we recommend the type 671 model<\/strong>, specifically developed for high-pressure applications<\/strong>.<\/p>\n
