This embodiment is particularly suitable for providing a lighting device

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 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.
