Circular Sight Glass Fittings Type 320 - PN10/16
According to DIN 28120
Tank Sight Glass Type 320 PN 10/16
Our round tank sight glasses type 320 are welded onto or into a vessel wall to allow observation or illumination of the inside of the vessel. ACI tank sight glasses type 320 are designed according to DIN 28120 and can easily be used as a replacement part for already existing fittings according to DIN 28120. A sight glass made of chemically highly resistant borosilicate glass DIN 7080 (or similar) is clamped between two high-quality stainless steel flanges and proven quality seals. Our tank sight glass meets all standard operating conditions such as resistance to vacuum and an operating pressure of up to 16 bar(g).
Beyond the definitions of DIN 28120, we also offer the Type 320 in special sizes of DN 250 and higher. These sizes, which are not specified in the standard, are also designed in full conformity with DIN 28120 and DIN 7080 (or similar), so that even in such special cases it is possible to utilise the application limits according to the standard.
Our tank sight glasses type 320 are made of the high-quality stainless steel 1.4571 (316Ti), which our customers have appreciated for years. The glass material used is borosilicate glass 3.3 according to DIN 7080 (or similar), which has proven itself in the industry. The sealing of the fitting is done with flat gaskets adapted to your needs from an extensive range of materials, which offers not only the widely used fibre gaskets but also more demanding materials such as PTFE (Teflon®), NBR, graphite and many branded gaskets.
If the maximum operating temperature of 280°C does not meet your requirements, or if the process conditions pose a problem even for the highly resistant borosilicate glass, an FEP or mica protective screen specially adapted to the fitting offers additional protection against steam and aggressive chemicals, such as alkalis up to a pH value of 14.
Like other of our sightglass fittings, our type 320 can be optionally equipped with SV1 spray devices, SGW or SWII type wipers (with flexible shaft) or lights.
