How Manual Globe Valves Work Manual globe valves are essential components in various industries such as oil and gas, pharmaceuticals, water treatment, and chemical manufacturing. These valves regulate and control the flow of liquids or gases by opening or closing a movable disk or plug, located in the valve body. The disk or plug may be moved up or down by a threaded stem that extends to the top of the valve, where it is actuated manually. Key Components of Manual Globe Valves A manual globe valve is composed of four key components, which include the valve body, disk or plug, stem, and handwheel or lever. The valve body is made of durable materials such as stainless steel, carbon steel, or cast iron, depending on the application requirements. The disk or plug also made of the same material as the body ensures a tight seal to prevent leakage. The stem is usually made of stainless steel and has a threaded tip that engages with the disk or plug, and it moves up or down to control the flow of the liquid or gas. Lastly, the handwheel or lever is used to actuate the stem, moving the disk or plug to open or close the valve. Working Mechanisms To open a manual globe valve, the handwheel or lever is turned counterclockwise, lifting the stem, and moving the disk or plug away from the valve seat. This creates an opening for the liquid or gas to flow through. When the valve is closed, the handwheel or lever is turned clockwise, which lifts the stem, causing the disk or plug to make contact with the valve seat, effectively sealing off the flow of the liquid or gas. Advanced Technology and Efficiency in Production Processes The advanced technology used in the manufacture of manual globe valves ensures that they are durable, reliable, and efficient. For example, reduced port globe valves, also known as flow-restricting valves, allow for precise regulation of flow while reducing the pressure drop, thus improving the energy efficiency of the system. Moreover, valve manufacturers have introduced and implemented advanced leak detection and prevention technologies that ensure that the valves operate without leakage, which is crucial in system efficiency. Application and Examples Manual globe valves are widely used in various applications such as fluid control, hydraulic systems, and steam applications. For instance, they are part of sophisticated control systems in power plants, where they are used to regulate flows of water and steam. In chemical manufacturing, manual globe valves are used in controlling and regulating chemical processes.
