G2/G3 Series Globe Valves
What is it?
The Belimo G2 and G3 Series threaded globe valves provide precise hydronic control for HVAC systems, delivering accurate temperature and flow control where it matters most.
Why it matters:
These valves help improve comfort, reduce energy waste, and ensure stable system performance—especially at low flow conditions.
- G2 Series: 2-way valves for modulating flow through heating and cooling coils
- G3 Series: 3-way valves for mixing or diverting water in hydronic loops
Available in ½in to 2in sizes, these valves deliver tight shutoff, stable modulation, and reliable performance in hot water, chilled water, glycol, and select steam applications when paired with the appropriate actuator.
How does it work?
The Belimo G2 and G3 globe valves modulate water flow by precisely positioning the valve plug, allowing smooth, accurate control as system demand changes.
Why it matters: Their modified equal percentage flow characteristic helps prevent temperature swings and “hunting,” especially at low flow conditions.
- In 2-way applications, the pressure-compensated design helps achieve tight close-off with less actuator force, improving reliability.
Enhanced performance: When paired with a Belimo actuator, these valves respond accurately to control signals to maintain consistent coil or loop temperatures.
What they're saying:
Belimo G2 and G3 threaded globe valves are engineered for demanding HVAC applications, delivering precision and reliability.
Why it matters: These valves meet ANSI Class VI leakage standards, providing tight shutoff to minimize bypass and temperature drift.
- Up to 100:1 rangeability for stable control at low flow conditions
- Pressure-compensated 2-way design helps achieve reliable close-off with lower actuator torque
Features: With ANSI Class 250 pressure ratings and broad fluid compatibility, these valves pair seamlessly with Belimo actuators for consistent, repeatable control.
Bottom Line:
The Belimo G2 and G3 threaded globe valves are easy to select, install, and commission when applied correctly.
Why it matters: Standard threaded connections and flexible actuator options make these valves a natural fit for both new construction and retrofit applications.
- Clear sizing data and application support from Stromquist & Company help ensure proper selection and reduce costly mistakes.
