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.
