Product information
The flow sight glass type 596 with 4 sight openings in 2-way design as a welded construction is a particularly robust version of our flow sight glasses.
A clear advantage of the version with four sight openings is that the user receives an almost 360° overview of the process – and that at very high operating pressures. This allows optimal observation of the flow of the medium and comprehensive control of the process.
Type 596 is designed for operating pressures 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 596.
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 seals tailored to your needs from a comprehensive range of materials. This offers not only the common fiber material seals but also more demanding materials such as PTFE (Teflon®), NBR, novaphit® MST-XP, KlingerSil® C4400, and many other brand seals.
