–in screwdown valve needle acts perpendicular to the axis of flow –in oblique valve needle acts at 45 angle and offers comparativley more direct flow path. flow path is less torturous with reduced pressure drop than a globe valve. has good throttling x tics. –in angle valves needle acts on fluid against
Oct 13 2015 Globe Valve Typically the globe valve is made up of a baffle that breaks the inside of the water pipe that is usually concurrent to the pipe’s size.The baffle has a strong opening which is vacuum packed with a chiseled disc or a plug which is pressed down in the seats or opening concurrent to the water pipe to break the movement inside the tube.
A variation on the stem guided globe valve design is the needle valve where the plug is extremely small in diameter and usually fits well into the seat hole rather than merely sitting on top of it. Needle valves are very common as manually
May 30 2008 The brief answer is no. Globe valve A valve where a disc or for for instance for regulating globe valves a plug is moved screwed multiturn usually down to close the valve. A plug valve a valve where a cylindrical or sligtly cone formed plug with a throughgoing cylindrical opening is moved 90 degrees on the stem axis to open or close the

valve. 1. Move a disc or plug into or against an orifice for example globe or needle type valve . 2. Slide a flat cylindrical or spherical surface across an orifice for example gate and plug valves . 3. Rotate a disc or ellipse about a shaft extending across the diameter of an orifice for example a butterfly or ball valve . 4.
The needle valve has a mesh and machined body. This body can be forged carbon steel or stainless steel depending on the requirements of the services. A seat can be soft metal or composite similar to a globe valve. Needle valves are typically used in smaller sizes and are provided with screwed or socket weld endings.

A needle valve is a special kind of globe valve in which the plug is needle shaped rather than disc shaped. A needle valve is able to provide a very fine level of flow control which is useful for precision equipment.
A globe valve will often employ a handwheel which works on a lead screw to raise and lower the globe valve plug out of and into the orifice. In large valves a reduction gear may augment the handwheel to provide the operator some mechanical advantage when opening or
Globe valve is used for throttling flow control. Shut off is accomplished by moving the disc against the flow stream rather than across it as in the case with a gate valve. The flow pattern through a globe valve involves changes in direction resulting
