DCX3 Mechanically Adjustable Relief Valve

The single sealing adjustable relief valve combines safety and accuracy thanks to its finetuning system. A predefined pressure relieves the main circuit protecting certain devises or circuits.


  • Optimum cleaning thanks to PFA floating seal
  • Reduced setpoint value tolerance
  • High response accuracy in case of overpressure
  • Adapted to viscous fluid, with particles or abrasive
