Further details about pressure transmission fluids see general technical information TA_038. |
Hygienic design
The wetted surfaces made of stainless steel are executed according to EHEDG Doc.8 and ASME BPE SF3. |
In case of choosing the additional feature 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. |
Temperature error
In order to optimise the system we provide a detailed error calculation upon request. |
Weight
See data sheet |
Installation instructions
For diaphragm seals with clamp design an operation outside the permissible nominal pressure range is only permitted when using suitable clamping rings. Please note DIN 32676 on temperature resistance. |
Further information about diaphragm seals see general technical information TA_031. |
