Alwa-Kombi-4 Throttle Valves

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.

Alwa-Kombi-4 valve with internal threads in difference size come with temperature-controlled actuator for 50...60 ∞C temperature range.
