The ACI flow sight glass Type 550 with a cast casing is a solid flow sight glass for flange installation.
Type 550 is available in a range of steel and stainless-steel alloys with pressure equipment approval, such as GG25, GS-C25 or 1.4408. Other alloys according to your specifications can also be supplied on request.
The Type 550 flow sight glass is supplied as standard with flanges according to DIN EN 1092-1, but we can also apply other standards such as ASME B16.5 and even customised flanges according to your specifications.
Sealing for Type 550 is done with tried and tested flat materials from well-known manufacturers such as KlingerSIL C4400 or Frenzelit novaphit MST. Pure or modified PTFE is also available, as well as Garlock Gylon and a wide range of further sealing materials.
For higher operating temperatures or alkali media, it is possible to fit the viewing window with an additional mica protective layer.
It is possible to integrate cleaning devices such as wipers with PTFE silicone or NBR wiper blades or spray jets. Lighting with halogen or LED lights, also with ATEX approval, is likewise available on request.
