For hydronic balancing of circulation pipes according to DVGW work sheet W551/W553. Depending on the version, the Aquastrom T circulation valves are thermally or electronically controlled and are available with internal or external thread. Below the set temperature, the valve opens and automatically increases the hot water volume flow. The valve has an individual setting of the residual volume flow and automatically recognises automatic disinfection.
