SHORT DESCRIPTION - TANK SIGHT GLASSES TYPE 320 ACCORDING TO DIN 28120
The ACI Tank Sight Glass Type 320 is a round tank sight glass to be welded on or into the wall of a pressure vessel. Type 320 is manufactured in full accordance with the construction rules of DIN 28120 and suitable for an operating pressure of PN10 or PN16.
Due to DIN conformity Type 320 can easily be installed as a spare part for existing fittings complying with DIN 28120. Our tank sight glass fulfils all standard conditions including full vacuum compatibility and an operating pressure of up to 16 bar. Operating temperatures of up to 280°C are well within range of type 320. If a mica protection sheet is added, safe Operation at up to 300°C is possible! Of course, you can order matching mica sheets directly with your sight glass!
Expaning upon the definitions of DIN 28120, we can offer Type 320 with special sizing of DN250 and larger, as well as high temperature compatible quartz windows and of course matching gaskets. Although these variants are not listed in the standard documents, design and manufacturing closely follows the regulations provided in DIN 28120 and DIN 7080, so the stated operating conditions can be completely relied upon.
As for all our round tank sight glasses, our type 320 is optionally available with spray nozzles SVI, wipers of type SWI or type SWII (with flexible shaft) or light fixtures with LED or Halogen lights.
