Three-way flow sight glass for operating pressures up to 400 barg with flange connections according to DIN EN 1092-1.
The flow sight glass type 590 as a welded construction is a particularly robust version of our flow sight glasses.
The type 590 is designed for operating pressures of up to 400 barg and can be easily installed between flanges according to DIN EN 1092-1. Thanks to its standard lengths according to DIN EN 558-1, the sight glass is ideally suited for retrofitting in existing systems.
Even with larger nominal sizes, high operating pressures can be achieved with type 590.
The standard version with borosilicate glass is suitable for operating temperatures up to 280 °C, with an additional mica protection disc even up to 300 °C or 320 °C in combination with MAXOS® safety sight glasses according to DIN 7080.
The sealing of the fitting is done with flat gaskets tailored to your needs from a wide range of materials. This offers, in addition to the common fiber material gaskets, also more demanding materials such as PTFE (Teflon®), NBR, novaphit® MST-XP, KlingerSil® C4400, and many other brand gaskets.
