Belimo ZONE325N-80 Actuator

The Belimo ZONE325N-80 is a high-performance 3-way zone valve assembly featuring a 1-inch NPT female connection and a 8.0 Cv rating. Engineered for precision control in hydronic systems, this motorized zone valve utilizes a synchronous motor to ensure reliable 105 psi close-off pressure. The ZONE325N-80 actuator is designed for easy field installation with a one-hand removal mechanism, facilitating rapid maintenance in tight mechanical spaces. This HVAC zone actuator operates on a standard 24VAC power supply and is compatible with most low voltage thermostats and building automation controllers. With its robust forged brass body and EPDM seals, it provides superior flow regulation for fan coils and baseboard applications. Contractors rely on this Belimo zone valve for its high differential pressure capacity and consistent performance in closed-loop systems requiring on/off hydronic control.

• High Close-off Pressure: Rated for 105 psi to prevent leakage in demanding hydronic circuits.
• Simplified Installation: Features a twist-lock actuator mount for tool-free assembly and reduced labor time.
• Reliable Flow Control: 8.0 Cv rating provides precise fluid management for commercial and residential heating/cooling zones.
• Manual Override: Includes a manual lever for system flushing and emergency operation during power loss.

What is the maximum fluid temperature for the ZONE325N-80?
This 1-inch zone valve is rated for media temperatures ranging from 32°F to 212°F, making it suitable for chilled water and hot water applications.

Can I install this actuator in any orientation?
For optimal longevity, the actuator should be installed vertically or at a 90-degree angle; avoid mounting the motor upside down to prevent moisture accumulation.

Is the ZONE325N-80 compatible with glycol systems?
Yes, this 3-way valve is compatible with water-glycol mixtures up to a 50% concentration for freeze protection.
