Danfoss RA-U radiator valve 10 3/8" Angular running

Valves with pre-setting are used in water-borne two-line systems to ensure optimal distribution of the water in the heating system. The preset makes it possible to precisely set the calculated water flow. The preset is done without the use of tools. The RA-N has a red cover cap and the RA-U has a yellow cover cap. RA-U valves are mainly intended for heating systems with small flow volumes through the radiator. RA-UR valves are primarily intended for replacing existing FJVR valves on district heating systems.
