Product Details

The Belimo B221B+LF120 is a complete valve and actuator assembly featuring a 3/4-inch two-way brass ball valve paired with a 120-volt spring return electric actuator. This control valve assembly delivers reliable on/off control for hydronic heating, cooling, and general HVAC applications.

Key Specifications:

  • Valve Size: 3/4 inch (NPT threaded connections)
  • Valve Type: 2-way brass ball valve
  • Flow Coefficient (Cv): 24
  • Actuator Voltage: 120V AC
  • Control Type: On/Off (non-modulating)
  • Spring Return: Failsafe spring return to closed position on power loss
  • Close-off Pressure: 35 PSI
  • Direct mount actuator with manual override

The spring return feature ensures the valve automatically closes when power is interrupted, providing failsafe operation for critical systems. The actuator mounts directly to the valve body for a compact, integrated package. Ideal for chilled water, hot water, and glycol solutions in commercial HVAC systems, fan coil units, unit heaters, and zone control applications.

Good pricing and reasonably fast delivery. The parts came in multiple packages over several days, which I wasn't aware of, so initially I feared things hadn't been delivered...but after a couple of days, everything arrived and was as expected. Overall, will shop here again.
