DG20 Sight Glass, Tubular Type with Flange Connections

More informations

The sight glasses of the type series DG20 are extremely robust due to their design and can be used very functionally. They allow the inspection of filling and flow in pipelines.

The sight glass with flange connection is installed in the piping system with the appropriate sealing surfaces and enables reliable 360° monitoring of the function and performance of individual apparatus as well as of entire plants.

The DG20 sight glass is designed with flanges on both sides to suit DIN 1092-1 (DIN 2633, PN 10/16). Depending on the nominal size, pressures up to 6 bar are permissible.

The flow sight glass has no dead spaces, so that when the product is changed, the flow sight glass can be flushed / cleaned together with the pipeline.

There are no sediments in the sight glass when the pipeline is drained because the inside diameter of the sight glass corresponds to the inside diameter of the pipeline.

Typical Applications:

The sight glasses can be used in almost all pipelines. The borosilicate glass used allows the devices to be used for chemically very aggressive media. They are insensitive to contamination, as the inner surface is always rinsed by the flowing medium.

The sight glasses are therefore also excellently suited for sterile and antiseptic applications.
