V1810Y0015 DN15 mm, R1/2 Alwa-Kombi-4 valve with internal threads
SKU: V1810Y0015
Product overview
The Alwa-Kombi-4 is used as throttle valve for hydronic balancing of warm potable water circulation systems.
To achieve a hydronic balance the flow in the circulation pipe is throttled by manually presetting the valve. The valve can also be equipped with a thermal actuator which allows a regulation of the water temperature in the circulation system to the exact degree. The thermal actuator can be installed without interruption of the warm water supply. When the thermal actuator 50 - 60 °C (122 - 140 °F) is used, a thermal disinfection according to DVGW worksheet W551 and W553 is supported. Hydronic balance is also retained during the thermal disinfection process to ensure disinfection of all pipelines and risers.
