Information About B225+LF24
The B225+LF24 US combines the Belimo B225 characterized control valve with an LF24 US fail-safe actuator for reliable HVAC water flow control. The valve features a 600 psi body pressure rating, internal female NPT connections, and a 75° controllable flow range with a 0% leakage rate for A–AB. Its characterized disc provides an equal-percentage flow characteristic and is designed for chilled or hot water containing up to 60% glycol. The actuator operates on AC/DC 24 V power and provides 90° rotation with a 75-second motor running time and spring-return fail-safe operation.
Key Features:
- 2-Way Valve: Provides two-port flow control for hydronic heating and cooling systems.
- 1-Inch Size: Features a 1-inch [25 mm] valve body with internal female NPT connections.
- Cv 30: Provides a flow coefficient of 30 for high-capacity hydronic applications.
- Equal-Percentage Flow: Supports stable and precise flow control across the controllable range.
- Stainless Steel Trim: Includes stainless steel stem and ball components for compatible water applications.
- 24 V Fail-Safe Actuator: Operates on AC/DC 24 V power and provides spring-return positioning.
- On/Off Control: Provides two-position actuator control for valve opening and closing.
- 600 psi Pressure Rating: Provides a 600 psi rated valve body pressure capacity.
The B225+LF24 US delivers the reliability and precision required for hydronic HVAC flow control, coil regulation, and fail-safe valve applications.
