And with their ability to start, stop, and throttle fluid flow within a pipeline, it\u2019s easy to see why.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nGenerally speaking, the flow of globe vales is from down to up. It means the medium will go through from the disc downside and then out by the upside. Globe valves usually adopt a compulsory sealed design, so closing the valve offer pressure to the disc against the seat. So if you want to open the valve, the globe valve disc must overcome resistance made by stem and packing friction, medium pressure will offer adverse pressure which helps open the valve. It means you can use less force than the closing valve. So the stem diameter should be larger, to avoid stem bending fault. (depending on the metal material's physical performance of the stem ). In recent years, there are more and more valve pressure seals, the medium through the upper disc to the down disc, so the close valve force is smaller than the open valve force, valve shaft diameter is allowed to be smaller.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nBut some opinions disagree with it, especially for a globe valve with a larger size (for example, a size bigger than DN250), the globe valve usually adopts a valve pressure seal, and considering closing valve force, it is easy to reach the seal performance. But it should take the stabilization of the valve into consideration when the valve stem diameter is smaller than the seat diameter.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nBut how exactly do these valves work and what\u2019s the globe valve direction flow?\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>How do Globe Valves Work?<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nA globe valve is primarily designed to stop, start and regulate flow. It is comprised of a movable disk and a stationary ring seat in a generally spherical body. The seat of a globe valve is in the middle of and parallel to the pipe, and the opening in the seat is closed off with the disk. When the handle is turned, manually or through an actuator, a disc is lowered or raised by means of the valve stem. When the disc is fully lowered, the fluid flow is shut off. When the disc is fully raised, the fluid flow is at its maximum rate. When the disc is raised to the less than maximum level, the fluid flow is regulated in proportion to the vertical travel of the disc.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2 id=\"h-globe-valve-flow-direction\"><strong>Globe Valve Flow Direction<\/strong><\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\n-For low-temperature applications, globe and angle valves are ordinarily installed so that pressure under the disk. This promotes easy operation, helps protect the packing, and eliminates a certain amount of erosive action to the seat and disk faces.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\n-For high-temperature steam service, globe valves are installed so that pressure is above the disk. Otherwise, the stem will contract upon cooling and tend to lift the disk off the seat ( and leak).\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Flow to Open (FTO)<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nAlso referred to as standard or forward flow, or in globe valves, flow under the seat. Think about when you've controlled the flow of water from a garden hose with your thumb. Your thumb acts like the face of the plug in a globe valve - flow is pushing against your thumb to open a flow path for the water.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Flow to Close (FTC)<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nAlso referred to as reverse flow or in globe valves, flow over the seat.
