Belimo Z2ZN0072 Actuator 320720-756 Key Benefits: Efficient Combustion: Integrated

Key Benefits: Efficient Combustion: Integrated 30-second pre-purge and post-purge cycles ensure the heat exchanger is clear and safe for each cycle

This unit features 1 1/8" ODF (Outside Diameter Flare) sweat connections

which is the industry norm for reliable contractor-grade utility gauges

High-torque resistance prevents blade deformation during peak operational cycles

potentially leading to premature failure

Belimo Z2ZN0072 Actuator 320720-756 Key Benefits: Efficient Combustion: IntegratedThe Belimo Z2ZN0072 is a robust 2 way zone valve actuator and valve body assembly designed for precision hydronic flow control. Operating on 120V AC line voltage, this normally closed (NC) configuration ensures critical fail safe positioning during power loss. With a 3. 5 CV flow coefficient and a 3 4" NPT connection, it manages medium flow HVAC applications with minimal pressure drop. The forge brass Belimo zone valve body is rated for a 30 PSI close
