Belimo ZONE220N-50 Valve
The Belimo ZONE220N-50 is a high-performance 2-way zone valve designed for precise flow control in closed-loop hydronic systems. Featuring a 3/4" NPT female pipe thread connection and a 3.6 Cv rating, this valve is engineered for efficiency in baseboard, convector, and fan coil applications. The forged brass body ensures long-term durability under standard operating pressures, while the chrome-plated brass ball and EPDM O-rings provide a reliable bubble-tight shut-off, reducing thermal leakage and improving system delta T.
Installation is straightforward for contractors due to the compact footprint and the Belimo ZoneTight technology, which minimizes torque requirements and allows for the use of smaller, more efficient actuators. This normally closed zone valve is rated for a maximum fluid temperature of 212°F, making it a staple for high-demand commercial and residential heating environments. When performing a hydronic zone valve replacement, the ZONE220N-50 offers the reliability needed to prevent ghost flow and ensure consistent zone balancing.
- Low Power Consumption: Optimized for energy-efficient operation with compatible Belimo actuators.
- Zero Leakage: The 3.6 Cv ball valve design provides 0% leakage at 50 psi, significantly outperforming traditional paddle-style valves.
- High Close-off Pressure: Handles up to 75 psi close-off, ensuring control even in high-head pump systems.
- Field-Proven Reliability: Maintenance-free design reduces service callbacks and simplifies HVAC zone control troubleshooting.
Common Questions
What is the maximum pressure drop allowed for this valve?
The ZONE220N-50 is designed to operate effectively with a maximum differential pressure of 15-20 psi to avoid noise and cavitation issues in the piping.
Is this valve compatible with glycol-based systems?
Yes, this brass zone valve is compatible with water/glycol mixtures up to 60% concentration, provided the fluid temperature remains within the specified range.
Can the actuator be serviced without draining the system?
Yes, the actuator can be easily removed or replaced via the quick-release mechanism without breaking the hydraulic seal of the valve body.
