RAVV is self-acting thermostatic actuator primarily for use for temperature control in small hot water cylinders and to control flow temperatures in central heating systems.
RAVV can be combined with 2-way valves RAV-/8, VMT-/8 or VMA 15. Controller closes on rising temperature.
There is a special version with a section of the capillary tube coiled up to function as minimum temperature sensor. This version can be used to control air heating coils.
