SAF Viewports units are for use in low pressure applications (5 PSI) where 100% shutoff is not required.
The stainless steel slide arrangement in the gate gives added protection and life to the lens during operations and allows maintenance to be performed with added safety during vessel down-time. The Gate View Ports use the SAF Viewports standard line of gates as the primary components and incorporate a mating flange, gaskets, and the glass lens which is secured by a metal retaining ring.
Additional cooling can be obtained by adding a purge connection on the glass or vessel side of the gate housing.
Two choices of glass are available for varying temperature exposures and viewing requirements.
