Product Type: PROCESS VALVES Constant pressure valve.

To keep a constant pressure, the free flow section at the valve seat is reduced or enlarged by the valve cone. Via the valve shaft, the cone is connected to a regulating membrane, which will be backed up with air at a set pressure.

Field of application

All industries. For applications where a constant product pressure is a must


  • Capable of working in both flow directions (upstream and downstream)
  • Precise valve cone control with multi-layer flat membrane design
  • Minimum product loss because of the leakage detection
