  • maintenance-free

For integration into heat pumps or hydraulic systems. AZV can be used, for example, to switch between the operating modes "heating" and "cooling" or "heating" and "service water heating" as well as for switching over in water storage tank applications and is also suitable for shutting off. Different housing versions allow the zone valve to be customised to suit the application and location. Suitable for water and water/glycol mixtures with up to 50 % glycol.

Zone valve consisting of valve unit and electrical drive. The proven, robust design results in complete tightness with low pressure loss. A position indicator with a coloured traffic light system intuitively signals the switching state of the valve. The direction of flow of the valve in the rest position can be changed while the valve is installed, without the necessity to open the water circuit. Manual emergency operation is possible by removing the electric motor and turning the integrated hand wheel.
