In globe valves, the plug is connected to a stem which is operated by screw action using a handwheel in manual valves. Screwed bonnet: This is the simplest design available and it is used for inexpensive valves. When handle wheel will be rotated in clockwise direction, steam and gate will move in downward direction across the fluid flow line and gate will be tightly located between the two seats. This wide range of duties has led to the development of numerous variations of globe valves designed to meet a particular duty at the lowest cost. • Self aligning two piece packing gland. A globe valve is formed by a baffle that splits the interior of the pipe, usually parallel to the length of the pipe. They are named for their spherical body shape, with the two halves of the body being separated by an internal baffle. Product Range . Fisher DVC6200, Globe Control Valve, Globe Valve. The plug is also called a disc or disk. The baffle contains an opening that is sealed by means of a disc or flat plug being pushed down into the opening, or seat, perpendicular to the pipe, to stop the flow through the pipe. Bolted-bonnet: This is the most popular design and used in a large number of globe valves. The globe valve regulates the flow in the pipeline. Please contact us. Globe valves can be structured to handle flow in either direction. Figure 6.32 compares the inherent flow characteristic of a ball valve with a traditional double-beat globe valve of the same size. The body is the main pressure containing structure of the valve and the most easily identified as it forms the mass of the valve. https://www.theprocesspiping.com/introduction-to-globe-valve Globe valves may therefore be used for most duties encountered in fluid-handling systems. For diameters higher than DN 100, we provide the globe valve with balance disc, to facilitate the opening; in this case the valve has to be mounted in the opposite direction, with pressure over the shutter.
