Level indicator sight glass 330

stainless steel

The ACI level indicator Type 330 is an easy to mount fitting for the industrially proven borosilicate sight glass plates according to DIN 7081. The base flange of Type 330 is set into the wall of a container or pipe and is fixed all-round with a welding seam. The base flange has an indentation for glass and seals, which are held by a cover flange. Type 330 only needs a very low torque for the fixing screws, whilst still achieving very reliable sealing. Type 330, like most of our fittings, is available in a range of materials, including standard types of container steel such as S235, or standard stainless-steel alloys such as 1.4571 or 1.4404, but high-performance materials such as Hastelloy or duplex alloys are available on request. For the sealing, we use tried and tested high-quality flat seals from well-known manufacturers such as KlingerSIL C4400 or novaphit MST. It is also possible to supply pure PTFE seal plates and soft seals such as NBR or EPDM directly.
