Circular sight glass fitting type 390V PN 16 - Vacuum

Product catalog summary

Overview: The document details the specifications and installation guidelines for circular sight glass fittings, specifically type 390V, used for observation and illumination in vacuum applications. These fittings are designed with round flange housings and are compliant with DIN EN 1092-1 standards.

Specifications: The sight glass fittings are constructed with borosilicate glass (DIN 7080 or similar) and are capable of operating at temperatures up to 200°C, with higher temperatures available upon request. The pressure range is from -0.9 barg to 16 barg. The base flange materials include various stainless steel grades such as 1.4571 and 1.4404, among others. Seals are available in PTFE, FKM, NBR, Silicone, and EPDM.

Installation Notes: After welding the ends of the base flange, it is crucial to check for warping of the sealing surfaces. Rework may be necessary to ensure proper sealing. Torque values for bolting should be adhered to as per the working pressure and maintenance manual.

Product Code Structure: The product code provides a systematic way to identify the specifications of the sight glass fitting, including type, nominal size, pressure rating, base flange material, glass type, and gasket material.

Operating Conditions: The operating conditions are dependent on the choice of glass and seals, with specific temperature and pressure limits outlined for each seal type. For aggressive media, FEP or Halar® coated sight glass plates are recommended.

Optional Accessories: Accessories such as grid impact protection windows, metal fused safety sight glass, and LED lights for Ex and non-Ex areas are available. FEP protective screens are recommended for high pH environments.

Additional Information: The document includes a quick overview of the product's capabilities, including its suitability for liquid and gaseous media, and notes on custom designs and available accessories. The pressure-temperature limits are in accordance with DIN EN 1092-1 standards.
