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.
connection G1/2 A: approx. 110 g
connection G3/4 A: approx. 230 g
connection G1 A: approx. 360 g
