SHORT DESCRIPTION - RECTANGULAR LEVEL INDICATOR TYPE 435

Type 435 sight glasses are a series of   rectangular sight glasses characterized by a solid construction and a large field of observation. In the event of contact with aggressive media, we recommend using protective layers such as mica, KEL-F, PRFE or FEP to protect the glass surface from chemical and thermal influences.

In addition to borosilicate glass (described in the industry standard DIN 7081), we also use cheaper soda-lime glass (in accordance with DIN 8903) in the case where     your application   does not require high temperature resistance  .

The seal is made, as with most of our sight glasses, with flat high quality gaskets such as KlingerSIL C4400   or highly chemically resistant PTFE   in untreated or expanded form. Soft, but durable,   gaskets, such as silicone, EPDM or NBR, can also be installed at the factory.

As flange material, you can choose from our whole catalogue of high-quality types of steel and stainless steel, such as S235, 1.4571 or 1.4541. The internationally widespread stainless steel 1.444 is also available, along with high-performance alloys or duplex steel.

If it is necessary to replace the glass or seal, our competent team of technical and sales consultants will help to provide a solution as quickly as possible.
