Danfoss 003L3531 RAVK Thermostatic Actuator 35–75°C – HIU

The Danfoss 003L3531 RAVK is a self-acting thermostatic actuator used for temperature control in heating systems and Heat Interface Unit applications. It operates without an electrical supply and closes the associated valve as the sensed temperature rises. The 003L3531 version has a 35–75°C setting range and is approved for use with compatible RAV-/8, VMT-/8, VMA and KOVM valve bodies. Where fitted to a VMT valve, make sure the replacement valve size and connection arrangement match the existing HIU.
