Circular sight glass fitting type 318V - Vacuum - PN 2.5

Product catalog summary

Usage: Round sight glass fittings, specifically type 318V, are designed for observing and illuminating the interiors of closed containers such as boilers, tanks, and silos. These fittings are round flange types meant for welding, featuring a sight glass plate secured between seals, suitable for vacuum containers due to D-ring or O-ring sealing.

Operating Conditions: The operating conditions are limited by the gasket and depend on environmental variables. The temperature range is up to 150°C for soda-lime glass and up to 200°C for borosilicate glass. The pressure range is from -0.9 barg to 2.5 barg.

Materials: The base flange is made of 1.4571 stainless steel. The sight glass can be either borosilicate glass (DIN 7080) or soda-lime glass (DIN 8902). Gaskets are available in PTFE, FKM, NBR, Silicone, and EPDM. Screws are A2-70 or A4-70, with special materials available upon request.

Installation Note: After welding the base flange, check for warping of the gasket surface and rework if necessary. Adhere to specified tightening torques. The working pressure must be verified with the pressure device according to AD2000 Leaflet B9.

Structure: The sight glass fitting consists of screws, a cover flange, a glass cushion, the sight glass, a gasket, and a base flange.

Product Code: The product code provides details about the type, nominal size, base flange material, glass type, gasket material, and variant. For example, code 11-318V-100-1-1-1-000 indicates a standard version with DN 100, borosilicate glass, and PTFE gasket.

Optional Accessories: Available accessories include sight glass wipers, impact protection windows, safety sight glass, LED lights, and FEP protective screens.

Quick Overview: The fittings are suitable for both liquid and gaseous media, with nominal sizes ranging from DN 50 to DN 300. Custom manufacturing and sealing materials are possible, and various accessories are available.

Circular sight glass fitting type 318V - Vacuum - PN 2.5-1

Circular sight glass fitting type 318V -Vacuum - PN 2.5For welding in or on similar to DIN 28120 Ji Similar to DIN 28120 as a lightweight vacuum-compatible version2 USAGE Round sight glass fittings serve to observe and illuminate the interior of closed containers (boilers, tanks, silos, etc.). Sight glass fittings of type 318V are round flange fittings for welding in or on, completed with a sight glass plate that is inserted and tightly screwed between the seals. The D-ring or O-ring sealing makes it possible to use it for vacuum containers without any issues. INSTALLATION NOTE After welding the base flange, it must be checked whether the gasket surface has warped. If necessary, it must be reworked! Also pay attention to the specified tightening torques for the bolting! The working pressure does not apply to the base flange; it must be checked together with the pressure device according to AD2000 Leaflet B9! 2) Depends on environmental variables DRAWING Materials 10112025 - Subject to technical changes and errors!
