Circular Sight Glass Type 392 - PN16 with male thread connection Use: Observation and illumination of the interior of enclosed vessels (cauldrons, tanks, silos etc.). Sight glasses consist of round flange mountings to be welded into or onto a vessel, completed by a sight glass plate with appropriate seals

Circular Sightglass with weld adapted to the pipeline Application: Observation and illumination of the interior of enclosed vessels (cauldrons, tanks, silos etc.). Sight glasses consist of round flange mountings to be welded into or onto a vessel, completed by a sight glass plate with appropriate seals.)

Screwed Sight Glass DIN 11851 /EN 10357 for welding into or onto vessel wall complete with glass disc, gaskets and slotted cover nut Use: Screwed Sight Glasses are used for observation of processes inside Boilers, Vessels and Pipes. They are often employed in food service, dairy, breweries and pharmaceutical applications. Due to the high temperature tolerance sterilization is possible.

Round sight glass fitting DIN28121, PN10 / 25 - for bolting straight onto DIN flansche Application: Observation and illumination of enclosed vessels (boilers, tanks, silos etc.) DIN 28121 Sight glasses are round flange fittings compatible with PN10/25. Sealing is provided by a flexible seal, with metal to metal contact providing the necessary compression.

Round high-pressure sight glass fitting type 322 for screwing on counter flanges according to DIN EN1092 Application: Observation and illumination of enclosed vessels (boilers, tanks, silos etc.) Type 322 Sight glasses are round flange fittings compatible with flanges according to DIN EN 1092-1. Sealing is provided by a graphite gasket. The sight glass fitting is delivered pre-assembled and ready for Installation.

Round high-temperature sight glass fitting type 323 for screwing on counter flanges according to DIN EN1092 Application Observation and illumination of the interior of closed vessels (boilers, tanks, silos etc.). Type 323 sight glass fittings are equipped with suitable materials to allow operation at up to 200 °C.

Round sight glass fitting for screwing onto a manhole Application: Manhole Sight Glasses can be used to close off entry or inspection openings in the same manner as blind flanges. They include a pressure resilient sight glass mount, enabling visual inspection of a vessel even with closed off openings.

Flow sight glasses type 530 - PN16-40 designed as welded construction Use: Visual survey of flow and filling processes in piping. The sight glasses allow for a reliable observation of function and performance of single devices or complete plants. With this design, no significant amount of liquid will remain in the sight glass when installed horizontally. With standard sight glasses, liquid will remain in the sight glass body. This liquid will drain out with this design.

Safety sight glass type 585 with double glazing Use: Sight glasses with safety viewports of Type 585 are designed to withstand the maximum allowable pressure with only one single glass plate intact. This way, pressure containment is guaranteeed even if one of the glass plates is damaged. Between base and intermediate flange an O-Ring seal ensures tightness even if the inner glass plate has failed. Type 585 is a true safety sight glass!

Flow sight glasses type 591- with three Viewports Verwendung: Visual Checking of Filling and Flows in Piping. Sight Glasses allow for reliable Observation of Function and Performance in single devices or complete plants.Type 591 allows observation of the flow from three sides without sacrificing stability. This embodiment is particularly suitable for providing a lighting device
