Globe valve has the following advantages: 1. Simple structure, manufacturing and maintenance more convenient. 2 small work schedule, opening and closing time is short. 3. Good sealing, sealing surface friction, longer life expectancy. The shortcomings of the cut-off valve are as follows: 1. Fluid resistance is large, the required force is large when opening and closing. 2 does not apply to with particles, viscosity, easy to caking medium. 3. Adjust the performance is poor. The type of stop valve by the position of the threaded stem is externally threaded type, the female type. By media flow points, there are straight-through, DC and angle. Globe valve by sealing form points, there are packing seal globe valve and bellows seal valve. Shut-off valve installation and maintenance should note the following: 1. Handwheel, handle-operated shut-off valve can be installed in any position on the pipeline. 2. Handwheel, handle and Wei moving mechanism, do not allow lifting. 3. The flow direction of the medium should be the same as the arrow direction of the valve body.
