In-line diaphragm seals 1620 with clamp connection Main Features Directly integrated in the pipe Excellent cleaning behaviour Wetted parts 1.4435 / 1.4404 (316L) Compatible to SIP and CIP processes Easy and fast installation Applications Food & Beverage Laboratory & Medical Description This in-line diaphragm seals are used to design hygienic process connections for pressure gauges and protect the pressure gauges from high temperatures and aggressive process fluids. Process connection Clamp ISO 2852 In-line diaphragm seals with hygienic process connections ensure efficient cleaning processes and avoid pollutions and developing of bacterias in hygienic production processes. Body material 0 ... 1 bar to 0 ... 40 bar (see table below) Stainless Steel 1.4435 (AISI 316L) Diaphragm Stainless Steel 1.4435 or 1.4404 (AISI 316L) Surface roughness Wetted parts Ra ≤ 0.8 µm Option 1359: electropolished, Ra ≤ 0.5 µm (except welding) Diaphragm seals can be mounted to mechanical pressure gauges, switches or transmitters directly or with a flexible capillary. The filling fluid of the measuring system has to be choosen compatible to the application. For hygienic applications a choice of FDA conform filling fluids is available.
