Product Description
The stainless steel slide arrangement is the blast gate gives added protection and life to the lens during operation, and allows maintenance to be performed with added safety during vessel down-time. Additional cooling can be obtained by adding a purge connection on the glass or vessel side of the blast gate housing. Three choices of glass are available for varying temperature exposures and viewing requirements. Threaded sizes range from 2″ to 6″ NPT threaded openings. Temperature ratings apply only for the operating conditions of the glass. Ratings for housings vary on type of steel. The Blast Gate Observation Ports use the standard line of blast gates as the primary component and incorporate a glass lens, gaskets and rings securely retained with metal bushings.
