Technical Configuration by Adjustment Type
The 67C Series uses specific suffixes to identify the method used for pressure setting:
| Model | Adjustment Method | Ideal Use Case |
| 67CW | Wrench Adjustment | Standard installations where setpoints are rarely modified. |
| 67CH | Handwheel Adjustment | Applications requiring frequent, tool-free manual changes. |
| 67CD | Dial / Calibrated Scale | Precise tasks where visual verification of the setting is required. |
| 67CN | Non-Adjustable | High-security needs where tampering must be prevented. |
