A globe valve is a linear motion valve primarily used to start, stop, and regulate fluid flow in a pipeline. Its internal structure includes a movable disk-type element and a stationary ring seat in a generally spherical body—hence the name "globe" valve. When the actuator or handwheel is turned, the stem moves the plug up or down, altering the flow path and providing throttling control. This design offers a good shutoff capability and is well-suited for applications where precise flow regulation is required. Due to the tortuous flow path, globe valves tend to have higher pressure drops than other types, but they compensate with excellent control accuracy. They are often used in chemical processing, power generation, and oil and gas systems where controlled flow and tight sealing are essential. Globe valves can handle various fluids including steam, water, oil, and gas, and are available in manual, pneumatic, or electric actuation versions. Their versatility and dependable operation make them a top choice for systems requiring modulation or frequent operation.

In What Applications Are Globe Valves Commonly Used?

Globe valves are widely used in industrial systems where accurate flow control is critical. In the oil and gas industry, they are used to control fuel oil feed lines and cooling systems. In power plants, globe valves regulate steam flow in turbines and boilers, where precise temperature and pressure control is vital. HVAC systems rely on them to modulate the flow of chilled or hot water, contributing to energy efficiency and comfort. Water treatment facilities use globe valves for dosing and chemical injection processes. In the chemical industry, these valves handle corrosive or high-viscosity fluids with ease, especially when made from specialized materials. Pharmaceutical and food processing plants also use globe valves in applications requiring cleanliness and reliability. Due to their strong shut-off capability, globe valves are suitable for emergency stop scenarios as well. Whether in manual or automat
