Constructional design / case
| Basic body: | Volume reduced diaphragm base Material: stainless steel mat.-no. 1.4404/1.4435 (316L) |
| Diaphragm: | Flat diaphragm |
| Material wetted parts: | Diaphragm: Stainless steel mat.-no. 1.4435 (316L) Further materials upon request |
| Basic body: Stainless steel mat.-no. 1.4404/1.4435 (316L) |
Process connection
| Design: | G 1 A adjustable, metal-to-metal joint. Due to the rotary screw-in design no tor-sional forces are produced that could damage the sealing surface. |
| Tightening torque/Nominal pressure: | 20 Nm, max. nominal pressure 10 bar 50 Nm, max. nominal pressure 50 bar |
Mounting torque error
| At a tightening torque of 20 Nm: 1 mbar |
Measuring device connection
| See order details. |
| Material stainless steel mat.-no. 1.4301 (304) |
System filling
| See order details; further fillings upon request. |
| Further details about pressure transmission fluids see general technical information TA_038. |
Hygienic design
| The surface roughness of the wetted parts 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
| Diaphragm seal and screwed plug approx. 0.3 kg |
| Further information about diaphragm seals see general technical information TA_031. |
| Flame arrester MF21xx for connection of measuring devices to zone 0 see data sheet D6-025. |
Type series
| DE2130 |
