Circular sight glass fitting type 322 PN 40/160

Product information

The container sight glass type 322 for high-pressure applications is a solid fitting based on the design principles set forth in the industrial standard DIN 28121.

Through the significantly reinforced flange and the use of glass plates beyond the standard dimensions of DIN 7080, it is possible for us with type 322 to achieve operating pressures of up to 160 barg.

The tensioning of the glass occurs similarly to our proven type 322 through pre-tensioning screws. This ensures that the fitting only needs to be properly attached to the carrier flange in your system to achieve the necessary sealing.

An execution for elevated temperatures is also feasible through the use of appropriate seals and glass materials. Due to the high operating pressure, the installation of wipers and spraying devices is unfortunately not possible with type 322. Lighting based on LED lighting elements is available from us.

Should the borosilicate glass not meet your requirements similar to DIN 7080, or if the process conditions themselves pose a problem for the highly resistant borosilicate glass, a mica protective disc specifically adapted for the fitting offers additional protection against temperature and steam. FEP or Halar® coatings additionally protect the borosilicate glass against aggressive chemicals or caustics.
