Heimeier bypass T-piece 4154-02.000
  • Thermostatic three-way valve body without presetting
  • with automatic bypass control
  • the thermostatic three-way valve bodies are used in two-pipe pump heating systems
  • A retrofit thermostatic insert is available for use in single-pipe pump heating systems
  • when almost all Valves are closed at the same time, additional pressures build up in the heating system
  • the three-way valve blocks the radiator flow
  • the bypass to the return is fully opened
  • additional pressures are avoided and the pressure is kept almost constant
  • the bypass can be connected to the Radiators return with the corresponding bypass T-piece
  • Area of application Two-pipe or one-pipe pump heating systems
  • Features rules
  • Shut off
  • Avoidance of additional differential pressure
  • Ensuring minimum circulating water quantities
