Globe Valve Actuators
A globe valve actuator provides the mechanical force needed to open, close, or modulate a globe valve in HVAC and hydronic control systems. These actuators are commonly used to control heating and cooling coils, mixing valves, and other modulating flow-control applications.
Furnace Part Source carries a range of globe valve actuators for commercial and industrial HVAC control systems, including proportional, floating-point, and on/off configurations.
Common Globe Valve Actuator Types We Carry
Common actuator types include:
- Proportional (modulating) actuators that provide analog control for precise flow regulation.
- Floating-point actuators that respond to open/close signals for incremental positioning.
- On/off actuators for simple, two-position valve control.
- High-torque actuators for larger valve bodies requiring greater force.
How to Find the Right Globe Valve Actuator
Before ordering, locate the specification number stamped or printed on the actuator housing, typically near where the shaft exits the motor. Confirm the voltage, control signal type, and torque rating needed for your valve body.
For best fit, compare:
- Original actuator part number
- Voltage, such as 24V, 120V, or 230V
- Control signal type, such as on/off, floating-point, or proportional (2-10V)
- Torque rating and valve body compatibility

Globe Valve Actuator FAQs
What is the difference between proportional and floating-point actuators?
Proportional actuators use an analog signal (such as 2-10V) for precise, continuous positioning, while floating-point actuators move incrementally based on open and close signals from the controller.
Where do I find the specification number on my actuator?
The specification number is typically stamped or printed on the actuator housing near the point where the shaft exits the motor.
Can I replace a discontinued actuator with a current model?
Yes, in most cases. Manufacturers like Belimo regularly update actuator lines, and current models are generally designed to meet or exceed the specifications of the models they replace.
Do larger valves require higher-torque actuators?
Yes. Larger valve bodies typically require actuators with higher torque ratings to fully open and close against system pressure. Match the torque rating to your valve body's specification.
