Process connection
Design: | Sanitary connections design with union nut or threaded coupling: - DIN 11851 - IDF - SMS |
Nominal pressure/nominal width: | See table |
The sealing is not included in the scope of delivery.
Hygienic design
The wetted surfaces made of stainless steel are executed according to EHEDG Doc.8 and ASME BPE SF3 (Code: HY). |
We guarantee the following surface roughness values: |
Diaphragm foil: Ra ≤ 0.38 µm Laser welds: Ra ≤ 0.76 µm Turned parts: Ra ≤ 0.76 µm |
Further versions of hygienic design upon request. |
System filling
See order details; further fillings upon request. |
