For hydronic balancing in circulation pipes according to DVGW Code of Practice 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 a fixed residual volume flow and automatically recognises thermal disinfection. Depending on the version, it enables the maximum volume flow to be limited and shut off via an integrated regulating unit with reproducible presetting. 

The valves are made of silicon bronze. Depending on the version, they are equipped with a drain valve with hose connection and a thermometer. A temperature sensor for integration into the building management system can be retrofitted. Depending on the version, an insulation shell made of EPP according to the German Building Energy Act GEG and building material class B2 according to DIN 4102 is included in the scope of delivery or available as accessory.

The Aquastrom T valves control the hydronic balancing and the temperature-controlled regulation of the volume flows in potable water circulation pipes. The temperature setpoint can be blocked and lead-sealed. Depending on the version, the flow rate can be blocked.
