Flange standards: ANSI B16.5, DIN 2526.

Marked with standard, model number, series number.

Functions

Flushing rings are required for flange-mounted and sandwich type remote if the danger exists that the process conditions

and the geometry of the connection could

Deposits can be flushed away from the diaphragm through the holes in the side, or the pressure volume can be vented.

Different nominal sizes and forms permit adaptation to the respective process flange.

make the medium into deposits or blockages

The flushing ring is clamped between the process flange and the remote seal.
