As part of their commitment to service, Danfoss produces a range of built-in and remote sensors that fit directly to older RAV and RAVL valve bodies. Replacement sensors incorporate RA2000 sensor technology and design, and provide a simple and straight forward way to upgrade older radiator thermostats without the need to drain down the system.
