Belimo Z2ZN0072 Actuator
The 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-off pressure, preventing seat leakage in high-head pump systems. Engineered for seamless integration with thermostats and BMS controllers, the Z2ZN0072 utilizes a paddle-style movement for reliable shut-off in terminal equipment, fan coil units, and hydronic baseboard loops. It provides high-torque actuation and a manual lever for system flushing or emergency override, ensuring long-term duty cycle performance in demanding commercial and residential mechanical rooms.
Key Benefits Checklist- High-Torque 120V Actuation: Eliminates the need for step-down transformers in line-voltage control circuits.
- 30 PSI Close-Off: Prevents bypass and ghost flow in systems with high differential pressures.
- Normally Closed Logic: Default fail-safe position maintains system containment during power outages.
- Serviceable Design: Field-replaceable actuator head allows for maintenance without breaking the hydronic seal.
- NPT Threading: Standard 3/4 inch NPT female connections ensure compatibility with existing American pipe standards.
Is the Belimo Z2ZN0072 compatible with glycol systems?
Yes, this assembly is rated for use in closed-loop hydronic systems containing up to 50% ethylene or propylene glycol concentrations.
What is the maximum fluid temperature rating?
The valve body and paddle seat are designed to handle media temperatures up to 212°F (100°C), making it suitable for both chilled water and hot water applications.
Can the actuator be mounted in any orientation?
It is recommended to mount the actuator at least 5 degrees above the horizontal plane of the pipe to prevent moisture accumulation in the motor housing.
