cast steel globe valve,globe valve

A globe valve is a type of valve used for regulating flowin a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical spherical body. Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug can be screwed in to close (or shut) the valve. The plug is also called a disc or disk. In globe valves, the plug is connected to a stem which is operated by screw action in manual valves. Typically, automated valves use sliding stems. Automated globe valves have a smooth stem rather than threaded and are opened and closed by an actuatorassembly. When a globe valve is manually operated, the stem is turned by a handwheel. cast steel globe valve 1/with DN20 to DN400 2/with wcb material 3/with different standard
