Flow sight glass with sealing in the force shunt

Short description: Flow sight glass with sealing in force shunt

The ACI flow sight glass with sealing in the force shunt Type 581 is a flow sight glass with weld ends and PTFE-coated corrugated ring seal.

The sight glasses are made of safety borosilicate glass according to DIN 7080 and are sealed with a PTFE-coated corrugated ring seal according to DIN 28121.

Due to the completely closed glass frame, the sight glass pane is best possible protected laterally against damage. Like our tank sight glass type 321, the type 581 can be equipped with additional cleaning equipment such as wipers or spraying devices. Luminaires based on halogen or LED light sources with and without ATEX approval are also available ex works.

As additional protection against heat or alkaline media, it is also possible to install a mica disc in our flow sight glass type 581.

For temperatures outside the approved operating range of up to 200°C of the PTFE-encapsulated corrugated ring seal, we can also supply Type 581 on request with a graphite composite seal instead in order to make full use of the maximum operating temperature of 280°C for the glass pane. For even higher temperatures, quartz glass viewing windows are also available at an extra charge.

The body of the flow sight glass type 581 can be manufactured according to your requirements from a variety of steel and stainless steel alloys with pressure equipment approval such as P265GH or 1.4571. Special materials such as Hastelloy are also available on request.
