Flushing ring

Flushing rings are required for flange-mounted and sandwich- type remote seals (Order No. 7MF4900 ... 7MF4923) if the dan- ger exists that the process conditions and the geometry of the connection could cause the medium to form deposits or block- ages.

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

Deposits can be flushed away from the diaphragm through the holes in the side, or the pressure volume can be vented. Different nominal diameters and forms permit adaptation to the respec- tive process flange.

Process connection

For flanges to EN and ASME:

DN 50, 80, 100, 125; PN 16 ... 100 or

DN 2 inch, 3 inch, 4 inch, 5 inch; Class 150 ... 600

Standard design

Material: CrNi-Stahl, mat. No. 1.4404/316L

Sealing faces and flushing holes: See Selection and Ordering data
