View Ports
The strongest, most secure sanitary sight glass available, Viewport's mechanically prestressed windows are available in a sanitary clamp design for sight ports in processing applications or inline visual flow indicators.
Unlike some other sight glasses, Viewport sight glasses meet the USP Type 1 standard for pharmaceutical use.
Described as offering the optics of glass and the strength of steel, these glass elements provide a level of safety, and a useful service life, well beyond that provided by conventional tempered glass or plastic in sanitary service. Even at the most extreme temperatures (as high as 536° F) or in overpressure situations, sudden, total failure - that involving leakage or explosive shattering of the glass - essentially never occurs.
Viewports are manufactured to fit sanitary clamp connections. With
simple and fast installation with no risk of breakage, this sleek,
compact, one-piece design provides a cleaner look, less bacteria
traps and unsurpassed safety. The Viewport sight glass can
be used as a view port mounted on a ferrule, a “cross” for inline
visual flow indication or as a light port. Many other connection
types are also available, as shown on the reverse side. Materials
available include 2205 Duplex Stainless Steel, Hastelloy®,
Monel® and Inconel®.
