Inline sight glass with double glazing - Type 550-D
The ACI Inline Sight Glass Type 550D builds upon the design of the Type 550 with a cast body. It is a robust flow sight glass designed for installation on DIN/EN flanges.
The Type 550D enhances safety with its double glazing, providing protection against glass splinters and escaping medium in case of glass breakage. It is available in various steel and stainless steel cast alloys with pressure equipment approval, such as GG-25, GS-C25, or 1.4408. Other alloys, including Alloy C22, can be provided upon request based on your specifications.
The standard Type 550D comes with flange connections according to DIN EN 1092-1, but we can also accommodate other common standards such as ASME B16.5 and even provide special flanges based on your specifications.
Sealing for the Type 550D is accomplished with proven flat materials from well-known manufacturers, such as KlingerSIL C4400 or Frenzelit novaphit MST. Pure or modified PTFE, Garlock Gylon, and a wide range of other sealing materials are also available.
For higher operating temperatures or alkaline media, the sight glass can be equipped with an additional mica protection layer.
The installation of cleaning devices, such as wipers with PTFE, silicone, or NBR wiper blades, or spray nozzles, is possible at the factory with the Type 550D. Luminaires with halogen or LED light sources, including those with ATEX approval, are also available upon request.
