Unlike the 318 <\/a>and 320 <\/a>models, the 317 sight is not designed to be a pressure-retaining sight, but rather a simple observation window. This makes the 317 sight significantly lighter and slimmer than other sights of this type available on the market. <\/p>\n

Despite the lower requirements, our Type 317 product sight glasses are made from the same high-quality 1.4571 (316Ti) stainless steel that is so highly valued by our customers. The glass material used is industry-proven borosilicate glass 3.3, in accordance with DIN 7080 (or equivalent). The connection is sealed using flat gaskets tailored to your requirements from an extensive range of materials; in addition to the widely used fibre gaskets, we also offer more sophisticated materials such as PTFE (Teflon\u00ae), NBR, graphite and many other branded gaskets. <\/p>\n

If the maximum operating temperature of 280\u00b0C does not meet your requirements, or if the process conditions pose a problem even for the highly resistant borosilicate glass, a mica or FEP protective screen specially adapted for the connection offers additional protection against steam and aggressive chemicals, such as alkalis up to a pH value of 14.<\/p>\n

Like other circular product displays, the 317 display can be fitted with an SGW-type brush, spray nozzles or lights on request.<\/p>\n
