Product information
The sight glass fitting Type 322A for high-pressure applications is a solid fitting based on the construction principles defined in the industrial standard DIN 28121.
Thanks to the significantly reinforced flange and the use of glass plates beyond the standard dimensions of DIN 7080, we are able to achieve working pressures of up to 250 barg.
The tensioning of the glass is carried out similarly to our proven Type 322A through tension screws. This ensures that the fitting only needs to be properly fixed to the carrier flange in your system to achieve the necessary sealing.
An execution for elevated temperatures can also be realized through the use of suitable gaskets and glass materials. Due to the high working pressure, the installation of wipers and spraying devices is unfortunately not possible with Type 322A. Lighting based on LED light sources is available from us.
If the borosilicate glass similar to DIN 7080 does not meet your requirements, or if the process conditions themselves pose a problem for the highly resistant borosilicate glass plate, a mica protective disc specially adapted for the fitting offers additional protection against temperature and steam. FEP or Halar® coatings additionally protect the borosilicate glass from aggressive chemicals or lyes.
