Motorised valves use electricity to help control the flow of heated water in the home. Controlled and accurate flow of hot water around the heating system can help improve energy efficiency and increase comfort for the end-user.

The Danfoss’s H series ‘shoe’ valves are available in a wide range of sizes both copper and iron pipework. The high capacity bodies of the Danfoss H series incorporates two self-cleaning positive shut off shoes and allows the water to flow through the 2 port valves in either direction. Designed with a manual valve lever, the valves can be opened manually to simplify filling the system and future servicing.
