Radiator Valve Heads

Self acting, without auxiliary power. High quality fluid-filled sensor with fast aquisition of room temperature changes.

Mode of operation: The fluid-filled sensor responds to deviations from the room temperature setpoint. When the room temperature rises, the fluid inside the metal capsule expands, exerting pressure rtn71on the bellows and the stem which causes the valve to close so that the radiator’s heat output will be reduced. When the room temperature falls, the bellows expand, thereby opening the valve so that the radiator’s output will be increased again.

Technical specifications:

  • setpoint setting range: 8°C..28°C
  • permissible sensor temperature: 40°C
  • hysteresis: 1K, proportional band: 2K
  • conformity: CEN standard EN215-1
  • adaptors available for almost all radiator valves
