High-pressure flow sight glasses Typ 520

High pressure Sight Glass Type 520 - up to 400 bar

The ACI high pressure sight flow indicators type 520 have a solid body which is made of various stainless steel alloys such as 1.4541, 1.4571 or acid resistant special steels such as 1.4539. Depending on the pressure rating, flanges are welded on in accordance with DIN EN 1092-1 and tested within the scope of the AD2000 directive. On request, other materials such as nickel-based alloys or Hastelloy for the highest stresses are also available. The fittings are usually manufactured with two viewing windows, which allows observation of the processes from two sides or fluoroscopy of the process medium.

In the standard version, a sight glass made of thermally hardened borosilicate glass 3.3, specially manufactured for your application, serves as a viewing window. Depending on the temperature and chemical stress, sealing is done with flat gaskets precisely selected for your application, for example made of graphite (novaphit MST XP) or mica-based gaskets.

Due to the solid housing, our flow sight glass type 520 can be equipped with test connections for measuring instruments or additional process connections (e.g. internal thread) on request.

In the standard version, type 520 is designed for up to 400 bar within the scope of DIN EN 1092-1. If your process requires a higher operating pressure, simply contact us. The sight glass housing and the glass plates can be manufactured (depending on the size) for up to 400 bar.

Type 520 is pre-assembled at the factory and subjected to a pressure test with 1.5 times the nominal pressure.
