Belimo B313+LRB24-3 Valve Assembly
The Belimo B313+LRB24-3 is a precision-engineered 3-way characterized control valve (CCV) designed for modulating or on/off control in hydronic systems. Featuring a 1/2 inch NPT connection and a 4.7 Cv rating, this assembly utilizes a stainless steel ball and stem to ensure long-term durability against scaling and corrosion. The valve is paired with the LRB24-3 non-spring return actuator, providing 45 in-lb of torque with a versatile on/off or floating point control signal. Operating on 24VAC/DC, the actuator delivers consistent performance for air handling units and fan coil applications. This assembly is rated for Chilled or Hot Water with up to 60% glycol concentration. The TEFZEL valve seats and EPDM O-rings provide bubble-tight shut-off on Port A, ensuring high system efficiency and preventing thermal bypass in complex piping circuits.
Key Benefits for Technicians
- Optimized Flow Control: The specialized characterized disc ensures a linear flow percentage, preventing hunting in the control loop.
- Durable Construction: Stainless steel trim provides superior resistance to harsh water conditions compared to standard brass components.
- Flexible Installation: The LRB24-3 actuator allows for manual override and features a universal spindle for easy field adjustments.
- High Close-off Pressure: Designed to handle up to 200 psi close-off, ensuring reliable operation in high-rise commercial loops.
Common Questions
What is the difference between Port A and Port B flow?
Port A is the control port featuring the characterized disc for precise modulation, while Port B is the bypass port typically used in constant volume pumping configurations.
Can the LRB24-3 be mounted in any orientation?
The actuator can be mounted in multiple positions, but it should not be installed upside down (shaft pointing up) to prevent moisture ingress into the gear train.
Is this valve assembly suitable for steam applications?
No, the Belimo B313 series is specifically rated for water and glycol-based hydronic systems and should not be used in steam services.
