Product catalog summary

Overview: The document provides technical specifications and installation guidelines for the Type 550V flow sight glass, used for monitoring flow in pipelines. It is compatible with flanges according to DIN EN 1092-1 and is pre-assembled for installation.

Specifications:

Operating Conditions: Limited by the sealing system (novaflon® 500).
Materials: Flange/Body made of 1.4408; Glass options include Borosilicate glass DIN 7080 and Soda-lime glass DIN 8902.
Temperature: Up to 150°C for Soda-lime glass and 200°C for Borosilicate glass.
Pressure: Ranges from -0.998 to 16 barg.
Gaskets: Options include Graphite, C4400, PTFE, FKM, NBR, Silicone, EPDM.
Bolts: A2-70 / A4-70, with special materials available on request.

Installation Notes: Gaskets must fit sealing surfaces precisely. Screw material should match or exceed the quality of the sight glass body. Threads and screw heads should be lubricated. The installation must be stress-free, avoiding pipe forces, vibrations, and pressure shocks.

Execution: DN 15 – 50 use rectangular flanges, while DN 65 – 200 use round flanges.

Product Code Explanation: The product code (e.g., 11-550V-6-2-3-1-18-0) details the type, nominal size, pressure, body material, glass type, gasket, and variant.

Operating Conditions: Suitable for both liquid and gaseous media, with nominal diameters ranging from DN 15 to 200. The product is TÜV pre-tested.
