Belimo B218B+LF24-SR-S NPT Control Valve with Actuator Cv - 3/4 2-Way 7.4 24V

The Belimo B218B+LF24-SR-S is a complete control valve assembly featuring a 3/4" NPT brass ball valve paired with an LF24-SR-S electric actuator for precise fluid control in HVAC applications.

Valve Specifications:

• Valve size: 3/4" NPT threaded connections
• Configuration: 2-way brass ball valve
• Flow coefficient (Cv): 7.4 for accurate flow control
• Body material: Lead-free brass construction for potable water compatibility
• Valve type: Characterized control valve (CCV) for linear flow characteristics

Actuator Features:

• Power supply: 24V AC/DC universal voltage
• Control signal: 2-10 VDC proportional control
• Spring return mechanism for fail-safe operation
• Auxiliary switch (SW) for position feedback or alarm functions
• Running time: Typically 90 seconds for full stroke
• Torque rating: 35 in-lb (4 Nm) for reliable valve operation

This valve assembly is ideal for heating, cooling, and domestic hot water systems requiring accurate modulating control with fail-safe spring return functionality. The proportional control allows for precise temperature regulation, while the auxiliary switch enables integration with building automation systems for monitoring valve position.
