For DIN EN applications at temperatures under -10 °C please proceed in accordance to AD-2000 Merkblatt W10:
• Load case II: under -10 °C / 14 °F to -60 °C / -76 °F, pmax = PN x 0.75
• Load case III: under -60 °C / -76 °F to -85 °C / -121 °F, pmax = PN x 0.25
Please notice: from 300 °C / 572 °F a bellows or suitable spring material e.g. Inconel X750 should be selected (refer to LDeS 3001.19).
For DIN EN applications at temperatures under -200 °C please proceed in accordance to AD-2000 Merkblatt W10:
• Load case II: under -200 °C / -328 °F to -255 °C / -427 °F, pmax = PN x 0.75
• Load case III: under -255 °C / -427°F to -273 °C / -459 °F, pmax = PN x 0.25
The temperature is limited by the standard inlet body. For applications up to 538 °C/1000 °F (temperature limit of outlet body) a suitable inlet body material and a
bellows or Inconel spring is requiered.
Min. set pressure high pressure bellows = Max. pressure standard bellows.
Because there is no open bonnet for this type available, please use at a temperature of 300 °C (572 °F) a stainless steel bellows or a specific high temperature
model without a bellows.

For DIN EN applications at temperatures under -10 °C please proceed in accordance to AD-2000 Merkblatt W10:
• Load case II: under -10 °C / 14 °F to -60 °C / -76 °F, pmax = PN x 0.75
• Load case III: under -60 °C / -76 °F to -85 °C / -121 °F, pmax = PN x 0.25
Please notice: from 300 °C / 572 °F a bellows or suitable spring material e.g. Inconel X750 should be selected (refer to LDeS 3001.19).
For DIN EN applications at temperatures under -200 °C please proceed in accordance to AD-2000 Merkblatt W10:
• Load case II: under -200 °C / -328 °F to -255 °C / -427 °F, pmax = PN x 0.75
• Load case III: under -255 °C / -427°F to -273 °C / -459 °F, pmax = PN x 0.25
The temperature is limited by the standard inlet body. For applications up to 538 °C/1000 °F (temperature limit of outlet body) a suitable inlet body material and a
bellows or Inconel spring is requiered.
Min. set pressure high pressure bellows = Max. pressure standard bellows.
Because there is no open bonnet for this type available, please use at a temperature of 300 °C (572 °F) a stainless steel bellows or a specific high temperature
model without a bellows.
