Thermostatic radiator valve with remote temperature head - has manual temperature adjustment on remote head instead of valve

摘要

The valve has a room sensor (100) and a valve operating head (200) connected by a length of capillary tubing (123). The room sensor has a liquid filled container (120) within which is a bellows dipping into the liquid. The upper end of the bellows is fixed to the top of the container and the lower end is free to move. When the cap (150) on the sensor is screwed down the lower end of the bellows is pushed further into the liqudi which is then pumped through the capillary tube to the valve operating head where it compresses the bellows (226) which moves the radiator valve. The design is advantageous for heaters in inaccessible places since the room unit is always readily accessible.
