What is a Globe Control Valve?<\/h2>\r\n\r\n\r\n\r\n\r\nWhen precise control is needed, globe valves are the favorite in many industries. Globe valves use the linear motion of a plunger that seats in a seat in a plane that divides the upper and lower half of the valve. In 2-way globe valves, the lower half is connected to the inlet port, and the upper half is connected to the outlet. On 3-way globe valves, there is a third port directly below the seat. There are 2 different styles of globe valve, each for a specific function:\r\n\r\n\r\n\r\n\r\n\r\nGET ACTUATED GLOBE VALVE PRICE<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n

Its design includes superior proportional control characteristics and safety features for a wide variety of applications, ranging from common fluids to the most aggressive chemicals. Accurate fluid control is achieved by positioning the valve plug to vary the aperture between the plug and the seat ring. The valve design allows the use of different plug\/seat sets to provide desired flow versus travel characteristics. A wide range of controllable CV is available, from 0.23 to a maximum of 105. Reduced trim is an option.\r\n\r\n\r\n\r\n\r\n
Applications of Actuated Globe Valves<\/h2>\r\n\r\n\r\n\r\n\r\nActuated Globe valves are available in a variety of sizes (NPS 1\/2 thru 36) and provide users with high performance and reliability. They can help solve an array of application needs from big to small, hot to cold, and general to severe.\r\n\r\n\r\n\r\n\r\n\r\nBonnets are available in different styles to accommodate different application temperatures. This primarily includes standard bonnets and optional extension bonnets, which may be used to protect packing materials when the valve is used in extremely hot or cold applications.\r\n\r\n\r\n\r\n\r\n\r\nThere are also special packing configurations for applications that require the packing system to maintain fugitive emission concentrations below environmental standards.\r\n\r\n\r\n\r\n\r\n\r\nSome of the most typical applications of globe valves include cooling water systems, fuel oil systems, feedwater or chemical feed systems, boiler, and main steam vents and drains, and turbine lube oil systems.\r\n\r\n","parent":0,"count":7,"filter":"raw"},{"term_id":3226,"name":"Cage Guided Control Valve","slug":"cage-guided-control-valve","term_group":0,"term_taxonomy_id":3226,"taxonomy":"post_tag","description":"\r\n\r\nGET CAGE GUIDED CONTROL VALVE PRICE<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n\r\n\r\n
What is Cage Guided Control Valve?<\/h2>\r\n\r\n\r\n\r\n\r\nA more modern version of the globe valve design uses a piston-shaped plug inside a surrounding cage with ports cast or machined into it.\r\n\r\n\r\n\r\n\r\n\r\nThese cage-guided globe valves throttle flow by uncovering more or less of the port area in the surrounding cage as the plug moves up and down. The cage also serves to guide the plug so the stem need not be subjected to lateral forces as in a stem-guided valve design.\r\n\r\n\r\n\r\n\r\n\r\nThe Cage guided control valve is a balanced valve that can be used as a dump valve, pressure regulator, suction controller, recirculation valve, and plunger lift applications. Compared to the stem-guided series, cage guided control valves feature larger trim sizes (available in 2\" to 10\" end connections) for higher valve coefficients (Cv). Cage guided control valves can be equipped with an optional electric drive or operated with compressed air to meet zero-emission requirements.\r\n\r\n\r\n\r\n\r\n

<\/figure>\r\n\r\n\r\n\r\nStructure of Cage Guided Globe Valve<\/h2>\r\n\r\n\r\n\r\n\r\nCage-guided globe valves are available with both balanced and unbalanced plugs. A balanced plug has one or more ports drilled from top to bottom, allowing fluid pressure to equalize on both sides of the plug. This helps minimize the forces acting on the plug which must be overcome by the actuator:\r\n\r\n\r\n\r\n\r\n

<\/figure>\r\n\r\n\r\n\r\n\r\nUnbalanced plugs generate a force equal to the product of the differential pressure across the plug and the plug\u2019s area (F = PA), which may be quite substantial in some applications.\r\n\r\n\r\n\r\n\r\n\r\nBalanced plugs do not generate this same force because they equalize the pressure on both sides of the plug, however, they exhibit the disadvantage of one more leak path when the valve is in the fully closed position (through the balancing ports, past the piston ring, and out the cage ports):\r\n\r\n\r\n\r\n\r\n![\"\"](\"https:\/\/zecovalve.com\/wp-content\/uploads\/2022\/11\/Cage-guided-globe-valves-principle.webp\")
<\/figure>\r\n\r\n\r\n\r\n\r\nThus, balanced and unbalanced cage-guided globe valves exhibit similar characteristics to double ported and single-ported stem- or port-guided globe valves, and for similar reasons.\r\n\r\n\r\n\r\n\r\n\r\nBalanced cage guided valves are easy to position, just like double-ported stem-guided and port-guided globe valves.\r\n\r\n\r\n\r\n\r\n\r\nHowever, balanced cage-guided valves tend to leak more when in the shut position due to a greater number of leak paths, much the same as with double-ported stem-guided and port-guided globe valves.\r\n\r\n\r\n\r\n\r\nComponents of Cage Guide Globe Valve<\/h2>\r\n\r\n\r\n\r\n
