Features

  • Multifunction valves, for use as expansion valve, hot gas bypass regulator, evaporator or condenser pressure regulator, etc.
  • Fully hermetic design (no screw connections between the valve body and motor part)
  • For use with all common refrigerants (HFC, CFC) and subcritical CO2 applications
  • Stepped ...
  • Multifunction valves, for use as expansion valve, hot gas bypass regulator, evaporator or condenser pressure regulator, etc.
  • Fully hermetic design (no screw connections between the valve body and motor part)
  • For use with all common refrigerants (HFC, CFC) and subcritical CO2 applications
  • Stepped motor operation
  • Very fast opening and closing times
  • Good precision and excellent repeat accuracy
  • Biflow versions for heat pumps
  • Closing function means an additional solenoid valve is not required
  • Flow rate linearly proportional to step rate
  • Large regulating range (10 ... 100%)
  • Proportional regulation of mass flow avoids refrigerant hammering in the refrigeration circuit
  • Motor and valve directly coupled for excellent reliability (no gears)
  • Valve slider and seat made from ceramic for minimal throughput losses and low wear
  • Patented in Europe (no. 0743476), USA (no. 5735501)
  • Corrosion-resistant stainless steel housing
  • PS: 45 bar
  • TS: Uniflow: -50 to +100 °C, Biflow: -40 to +80 °C
