Why Globe Valves

When precise temperature and flow control matter, globe valves are the right tool for the job. Unlike on/off or quarter-turn valves, globe valves are designed for true modulation, delivering smooth, accurate control across the full operating range of an HVAC system—especially at part load.

Globe valves provide stable low-flow performance, tight shutoff, and predictable control, helping reduce temperature swings, valve hunting, and unnecessary energy waste. The result: better comfort, improved efficiency, and fewer callbacks over the life of the system.

Belimo globe valve actuators and retrofit linkages are built for strength and flexibility.

Expanded options now offer 112–337 lbf force and 0.6–2" travel (15–50 mm), simplifying selection, installation, and service.

Where Globe Valves Make the Biggest Impact

Globe valves are most effective in applications where control quality directly affects performance and comfort, including:

Heating and cooling coils in air handling units (AHUs): Accurate modulation ensures consistent discharge air temperature and prevents coil bypass at low load.
Fan coil units in multifamily, hospitality, and dormitory buildings: Smooth control and tight shutoff reduce noise, overheating, and occupant complaints.
Unit ventilators in schools and universities: Globe valves perform reliably during shoulder seasons when precise low-flow control is critical.
Terminal reheat coils: Tight shutoff prevents unwanted reheat, improves energy efficiency, and maintains zone comfort.
Hydronic mixing and diverting loops: Globe valves deliver stable mixed water temperatures for boiler protection, coil control, and system balance.

The Bottom Line: If an application requires accurate modulation, dependable shutoff, and consistent performance, a globe valve is essential. It’s not just about controlling flow—it’s about controlling outcomes: comfort, efficiency, and long-term system reliability.
