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.

Think about when you've controlled the flow of water from a garden hose with your thumb.
