Belimo B230+LF24-SR Control Valve Cv Spring Return - 1.25 2-Way 19 24V 2-10VDC

The Belimo B230+LF24-SR is a 1.25-inch two-way characterized control valve (CCV) designed for precision control in HVAC systems. This valve assembly combines a brass valve body with an integrated actuator for modulating flow control in heating and cooling applications.

Key Specifications:

• Valve size: 1.25 inches (DN32)
• Flow coefficient (Cv): 19
• Valve type: Two-way characterized control valve
• Actuator voltage: 24V AC/DC
• Control signal: 2-10 VDC modulating input
• Spring return for fail-safe operation
• Threaded NPT connections

Features:

• Spring return actuator automatically closes valve upon power failure for safety
• Modulating 2-10 VDC control signal provides precise flow regulation
• Characterized valve plug provides equal percentage flow characteristics
• Compact integrated design saves installation space and time
• Suitable for hot and chilled water systems
• Close-off rating suitable for most HVAC applications

This valve assembly is ideal for variable flow systems in commercial buildings, including fan coil units, unit heaters, heat exchangers, and terminal units where precise temperature control is required.
