Type 319 - PN6


The ACI Tank sight glass Type 319 is, like our Type 320, designed based on the established construction rules of DIN 28120. In comparison to our 100% compliant sight glass 320, type 319 uses a thinner and therefore cheaper glass which meets the requirements of PN6. This allows you to save costs and still meet the requirements of your special application!

As you know from our tank sight glass product range, Type 319 can be equipped with wipers, spray nozzles or light fixtures, as well as the mounting of optional lights is also possible with type 319 and can be ordered from us!

The use of sealing materials and highly resistant flange materials tailored to your application ensures that you can make full use of the usual application possibilities of borosilicate glass 3.3 according to DIN 7080. Should your system itself reach the limits of this highly resistant material, Type 319 can also be equipped with a mica disc on request, which allows it to be used even with aggressive basic liquids and temperatures up to 300°C. The mica disc can also be used for the production of a wide range of applications. For even more aggressive media, we can offer you a protective disk made of FEP.

If our standard range of fibre gasketsgraphite with and without spit plate, PTFE, NBR or EPDM does not meet your requirements, the use of application-specific special materials is no obstacle.
