Flow sight glass Type 530 - PN16 - 40

SHORT DESCRIPTION - flow sight glass as welded construction

The ACI flow sight glass Type 530 is a welded construction with flange connections in accordance with DIN EN 1092-1. The viewing windows facing each other allow illumination and observation of the medium flowing inside.

Due to the welded construction made of pipes, the ACI Type 530 Flow Sight Glass saves a large part of the weight compared to the widely used sight glass fittings with cast housings, without sacrificing pressure resistance. As with most of our sightglasses, the glass discs are made of high-quality borosilicate glass DIN 7080 (MAXOS®), or according to the standard, specially manufactured glass discs if your operating pressure exceeds the working range of the standard configuration. For very hot media, our flow sight glass type 530 is alternatively available with high temperature quartz or sapphire glass discs. In chemically demanding operating conditions, we can protect the glasses with mica discs or protective discs made of FEP or PCTFE.

As casing material, in most cases we use high-quality stainless steel 1.4571 (316 Ti), which has a high acid resistance and is very suitable for most applications. If even this excellent material reaches its limits, our Type 530 sight glass fitting is also available in many other types of steel or stainless steel such as Hastelloy, duplex material, highly acid-resistant 1.4539 and many other alloys. Simply contact our competent team with your requirements or any specific material wishes and we will work out a solution together.

Quality flat seals made of tried and test materials such as KlingerSIL C4400, novaphit MST, pure PTFE, or for very high temperatures also mica compound materials, ensure soundly sealed openings.
