Belimo B219B+LRB24-SR-T 3/4" NPT Characterized Control Valve with Actuator

The Belimo B219B+LRB24-SR-T is a factory-assembled characterized control valve package designed for precise control in HVAC hydronic systems. This assembly combines a brass ball valve body with an electronic actuator for reliable proportional control of hot or cold water applications.

Key Specifications:

• Valve Connection: 3/4" NPT female threaded connections
• Flow Coefficient (Cv): 10
• Actuator Voltage: 24V AC/DC
• Control Type: Non-spring return (NSR) proportional control
• Control Signal: 0-10V DC or 2-10V DC input
• Fail Position: Remains in last position on power loss (non-spring return)
• Operating Pressure: Up to 400 PSI
• Temperature Range: -22°F to 250°F (-30°C to 121°C)

Features:

• Characterized ball design provides equal percentage flow characteristics for precise modulating control
• Integrated terminal block for simplified field wiring
• Compact direct-mount actuator eliminates need for brackets
• Brass valve body with chrome-plated brass ball and stainless steel stem
• 90-degree rotation from fully closed to fully open
• Manual override available for testing and emergency operation

This valve assembly is ideal for chilled water, hot water, and heating/cooling coil applications requiring proportional modulating control. The non-spring return actuator maintains valve position during power interruptions, making it suitable for applications where fail-safe positioning is not required.
