Flow sight glass type 550 PN 16/40 - DIN 11869 (old DIN 3237)-1

Flow sight glass type 550 PN 16/40 - DIN 11869 (old DIN 3237)With flange connections according to DIN 1092-1 Materials: DN 15 - 50 Rectangular cover flanges DN 65 - 200 Circular cover flanges USAGE For the observation of filling and flow in pipelines. The sight glass enables reliable monitoring of the function and performance of individual devices as well as of entire systems. Type 550 flow sight glasses are suitable for mounting on flanges according to DIN EN 1092-1. The sight glasses are delivered pre-assembled and ready for installation. Gaskets must be used that fit exactly to the sealing surfaces. The screw material should match or be of higher quality than that of the sight glass body. Screws must conform to the hole pattern of the flanges. Threads and screw heads should preferably be treated with lubricant. Tubular sight glasses should be mounted without tension - pipe forces, vibrations, and pressure shocks must not act on the fitting. 09122025 - Subject to technical changes and errors!

Flow sight glass type 550 PN 16/40 - DIN 11869 (old DIN 3237)With flange connections according to DIN 1092-1SAFETY DOUBLE GLAZING VACUUM APPLICATION The flow sight glass is equipped with a safety double glazing. In case of damage or destruction of the inner glass plate, the metal ring of the Meta® sight glass prevents the medium from escaping. The additional outer pane takes over the function of the first glass plate in this case and also maintains full operating pressure. This allows the system - especially in the case of hazardous media - to be shut down in a controlled manner and the defective...
