Constant Pressure Valves

Concept

  • HD Process supply hygienic constant-pressure valves. Constant-Pressure Modulating Inlet type maintains a constant pressure in the process line at the inlet side of
  • the valve. Typical applications are after separators, heat exchangers
  • or overflow valves.
  • Constant-Pressure Modulating Outlet maintains a constant pressure in the process line at the outlet side of the valve. Typical applications are before filling/bottling machines etc.

Working principle

The valves are remote-controlled by means of compressed air. A diaphragm/valve plug system reacts immediately to any alteration of the product pressure and changes position so that the preset pressure is maintained.
