Belimo B224+LRB24-SR-T Actuator
The Belimo B224+LRB24-SR-T is a high-performance 2-way characterized control valve and actuator assembly designed for precise hydronic flow control in HVAC systems. Featuring a 1" NPT connection and a 19 Cv flow coefficient, this nickel-plated brass ball valve utilizes a specialized TEFZEL characterizing disc to maintain an equal percentage flow characteristic, ensuring stable modulating control even at low flow rates. The LRB24-SR-T actuator operates on 24V AC/DC and accepts a 2 to 10 VDC proportional control signal, providing 45 in-lb of torque for reliable positioning. Built with EPDM O-rings and a stainless steel stem, this non-spring return actuator assembly is rated for a close-off pressure of 200 psi and a maximum media temperature of 250°F. The "T" designation indicates screw terminal strips for simplified field wiring, making it a rugged choice for chilled or hot water applications requiring high rangeability and bubble-tight shut-off.
- Equal Percentage Flow: Optimized for linear thermal output in heat exchangers.
- High Close-Off: Rated for 200 psi to prevent leakage in high-head applications.
- Proportional Feedback: Provides a 2 to 10 VDC position feedback signal to the DDC controller.
- Screw Terminal Connection: Simplifies installation without the need for additional pigtails.
- Zero Leakage: Rated for ANSI Class VI bubble-tight shut-off.
Common Questions
What is the maximum differential pressure for the B224+LRB24-SR-T?
This assembly is rated for a maximum differential pressure of 50 psi for quiet operation and a 200 psi close-off pressure rating to ensure shut-off against high pump heads.
Can this actuator be used with a 4 to 20 mA signal?
Yes, the LRB24-SR-T can be configured for a 4 to 20 mA control signal by installing a 500? resistor across the input terminals.
Is the LRB24-SR-T a fail-safe actuator?
No, this is a non-spring return (NSR) actuator. It will maintain its last position upon loss of power unless a backup power source is provided.
