GLOBE VALVE

What is a Globe Valve in HVAC?

In HVAC systems, a globe valve is a valve designed to manage and control the flow of fluids, such as water or refrigerant, by raising or lowering a disc or plug to either open or close the flow path.

Why Use It: Globe valves are essential in HVAC systems for regulating, throttling, or isolating flow. They are particularly beneficial when precise flow control is necessary, such as in hot water heating systems, steam systems, or chillers where modulating flow significantly impacts system performance.

Difference Between Globe Valve and Gate Valve: Globe valves differ slightly from gate valves. While gate valves are primarily used for completely shutting off flow, globe valves can serve multiple purposes, including on/off control, throttling, and flow balancing. They are mainly utilized for precisely controlling the flow of fluids rather than just opening or closing it.

Common HVAC Applications for Globe Valves:

• Regulating water flow in heating and cooling systems
• Controlling refrigerant flow in refrigeration and air conditioning systems
• Balancing flow across different parts of the system

Recommended globe valve manufacturers include L&T Valves, Kirloskar Valves, Hawa Valves, Amco, Apollo Valves, and GM Industries.
