The Danfoss AMZ 112 motorised zone valve is a two-way ball valve with an ON/OFF electric actuator, designed to control flow in domestic and commercial heating systems. Its compact design and ease of installation make it ideal for zone control in underfloor heating, radiator circuits and other applications where reliable opening and closing of the heat transfer medium flow is required.

The AMZ 112 valve combines a ball valve body with an integrated actuator powered by 24 V AC. The actuator opens and closes the valve electrically on the basis of a two-position (ON/OFF) control signal. The design also includes manual operation (MANUAL), which allows the valve to be mechanically switched to the OPEN or CLOSE position without electrical power – suitable during system commissioning or servicing. The valve is supplied in connection size Rp 1/2 (female thread G 1/2) with a nominal diameter of DN 15.
