390V Vacuum Sight Glass Flanged version
Our round vacuum tank sight glass fittings of Type 390V are precisely welded onto a vessel wall or pipeline to enable clear observation or illumination of the interior. Featuring welding ends according to DIN EN 1092-1 Type 11, these sight glass fittings are well-suited for the most common pipelines. Similar to our other sight glasses, a sight glass made of chemically highly resistant borosilicate glass to DIN 7080 or a similar standard is securely clamped between two high-quality stainless steel flanges and proven quality gaskets.
Our Type 390V sight glasses are crafted from the high-quality stainless steel 1.4571 (316Ti) that our customers have valued for years. The glass material used is borosilicate glass 3.3 according to DIN 7080 (or similar), a material well-established in the industry.
The fitting is sealed with ring gaskets, customized to your specifications, chosen from an extensive range of materials, including PTFE, NBR, EPDM, FKM, Silicone, and many other branded gaskets for special applications.
If the process conditions pose challenges even for the highly resistant borosilicate glass, a specially adapted FEP or mica protection screen offers additional defense against steam and aggressive chemicals, including alkalis up to a pH value of 14.
Similar to our other sight glass fittings, our Type 390V can be optionally equipped with SGW type wipers or lights.
