Belimo B238+AFRB24 Actuator
The Belimo B238+AFRB24 is a 1 1/2-inch, 2-way Characterized Control Valve (CCV) assembly designed for precise throttling in HVAC hydronic systems. This high-torque assembly features a stainless steel ball and stem, ensuring durability against corrosive pipe scale and cavitation in chilled or hot water applications. With a Cv rating of 19 and standardized NPT female pipe threads, it facilitates reliable flow regulation in demanding environments. The paired AFRB24 spring-return actuator provides 180 in-lb of torque, ensuring a fail-safe position upon loss of power. Operating on 24VAC/DC power, this on/off actuator is built for heavy-duty cycling. Technicians value the universal mounting plate and the integrated manual override, which simplifies commissioning and mechanical troubleshooting. Optimized for tight shut-off and high differential pressures, this assembly maintains system efficiency by preventing bypass leakage and ensuring linear flow characteristics.
Key Benefits- Stainless Steel Trim: High-grade ball and stem material offers superior chemical resistance and prevents premature wear.
- Fail-Safe Operation: The AFRB24 spring-return mechanism ensures the system returns to a safe state during power interruptions.
- Characterized Disc: Integrated disc provides equal percentage flow characteristics, preventing hunting and maintaining loop stability.
- High Close-off Pressure: Designed to handle high static systems without leakage across the valve seat.
- Simplified Installation: Standard 1 1/2" NPT connections allow for direct integration into existing piped headers.
What is the maximum fluid temperature rating for this assembly?
The B238 valve body is generally rated for hydronic fluids between 0°F and 250°F, depending on the concentration of glycol and system pressure.
Can the AFRB24 actuator be mounted in any orientation?
It can be mounted in various orientations, however, it is standard practice to avoid mounting the actuator below the horizontal plane of the pipe to prevents condensate damage.
Is this valve assembly suitable for steam applications?
No, the B238 CCV series is specifically engineered for water and glycol solutions and should not be used in steam systems.
