Constructional design / case
| Basic body: | Volume reduced diaphragm base Material: stainless steel mat.-no. 1.4435 (316L) |
| Diaphragm: | Flat diaphragm |
| Material wetted parts: | Diaphragm: Stainless steel mat.-no. 1.4435 (316L), alternative with delta ferrite content < 3% |
| Basic body: Stainless steel mat.-no. 1.4435 (316L), alternative with delta ferrite content < 3% |

| Further materials upon request. | |
| Profile gasket: (non wetted) |
Material: EPDM, optional FKM |
Process connection
| Design: | - G 3/4 A and G1 A with rotatable screwed plug. Due to the rotatable screw-in design no torsion forces are produced at the o-ring. |
| - G1/2 A with fixed screwed plug. | |
| Tightening torque: | > 30 Nm |
| Nominal pressure: | max. 60 bar |
| O-ring: (wetted) | - Material EPDM, temperature range: -40...150 °C |
| - Material FKM (Viton) temperature range: -10...200 °C |
Measuring device connection
| See order details. |
| Material stainless steel mat.-no. 1.4301 (304) |
System filling
| See order details; further upon request. |
| 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. |
| 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 hygienic designs upon request. |
Temperature error
| In order to optimise the system we provide a detailed error calculation upon request. |
