Flow sight glass type 591 PN 16/400

Product catalog summary

Overview: The document provides technical specifications and guidelines for the Flow Sight Glass Type 591, designed for monitoring flow and level in pipelines. It is suitable for both liquid and gaseous media and can be installed between flanges according to DIN EN 1092-1 standards.

Specifications:

Operating Conditions: The sight glass can operate under various pressure levels up to 400 barg and temperatures up to 320°C, depending on the glass and gasket materials used.
Materials: The body, cover, and connection flanges are made of 1.4571 stainless steel. Glass options include Borosilicate glass (DIN 7080) and Soda-lime glass (DIN 8902). Gasket materials include Graphite, C4400, PTFE, FKM, NBR, Silicone, and EPDM.
Dimensions: Nominal sizes range from DN 50 to DN 200, with dimensions corresponding to the nominal pressure level PN 16.

Installation Notes: Proper seals must be used to fit the sealing surfaces, and screw materials should be equivalent or superior to the flange material. Lubrication of screw threads and heads is recommended.

Product Code Explanation: The product code provides details on the type, nominal size, pressure rating, body material, glass type, and gasket material. For example, the code 11-591-8-2-1-1-4-000 corresponds to a standard version with specific configurations.

Operating Conditions: The suitability of the sight glass depends on the combination of glass and gasket materials, with specific temperature and pressure limits outlined for each combination.

Optional Accessories: Accessories include round mica discs for high-temperature applications, sight glass wipers, grid impact protection windows, metal fused safety sight glass, LED lights, and FEP protective screens for high pH environments.

Additional Notes: For aggressive media or steam, mica discs are recommended to protect the glasses. The pressure-temperature limits are in accordance with DIN EN 1092-1 standards.
