Information About B225+LF120-S US
The B225+LF120-S US is part of Belimo’s characterized control valve portfolio designed for accurate flow regulation in hydronic heating and cooling systems. The valve incorporates a precision-machined ball that provides true equal percentage flow control, ensuring stable modulation and predictable system response. Its factory-mounted LF120-S US spring return actuator operates directly on 120 V AC power and delivers dependable on/off control with automatic fail-safe positioning during power loss. The assembly is engineered for maintenance-free operation and long service life in commercial HVAC installations.
Key Features
- Characterized Control Valve Design: Precision ball geometry delivers true equal percentage flow control for stable and repeatable system performance.
- Integrated Spring Return Actuator: Automatically drives the valve to a predefined safety position upon power loss, supporting system protection.
- Line Voltage Operation: 120 V AC actuator eliminates the need for a separate control transformer in line-voltage applications.
- Tight Shutoff Performance: Rated for 200 psi close-off pressure with zero leakage for A–AB to ensure reliable isolation.
- Durable Valve Construction: High-pressure valve body rated to 600 psi supports long-term operation in demanding hydronic systems.
- Auxiliary Switch Integration: Built-in SPDT auxiliary switch provides end-position indication and control interlocking capability.
- Maintenance-Free Assembly: Designed for continuous-duty service without routine maintenance requirements.
The B225+LF120-S US delivers the reliability and precision required for safe, dependable on/off flow control in commercial HVAC hydronic systems.
