Technical Data

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.
