With an actuating force of 100 N and an actuating stroke of 4 mm, the ALPHA 5 guarantees precise valve control. It is controlled via room temperature controllers with two-point output or pulse width modulation. The low switch-on current (<550 mA for max. 100 ms) and the standby power of approx. Electrical installers benefit from the simple plug-in installation on valve adapters for the most common valve bases and heating circuit manifolds (not included in the scope of delivery) and the overvoltage protection.
