The opening and closing parts of the globe valve is a plug-shaped valve, sealing surface flat or cone, the valve in a straight line along the center line of the fluid.

 Closing the valve stem forms of exercise, lift rod (stem down, hand wheel lift), lift the rotating rod (the hand wheel and stem with rotating movements, nuts located in the body). The cut-off valve is only applicable to the fully open and fully closed is not allowed to make adjustments and to reduce expenditure. The cut-off valve is forced sealed valves, the valve is closed, the pressure must be applied to the valve to force the sealing surface does not leak. When media from the bottom of the valve into the valve, the operating force required to overcome the resistance, the friction force of the stem and the packing and thrust generated by the pressure of the medium, and close the valve force than the force to open the valve, Therefore, the diameter of the valve stem, otherwise they will be the failure of the stem top bend. In recent years, from the emergence of the self-sealing valve, globe valve flow direction of medium change from the top of the valve into the valve chamber, this time in the role of the media pressure, the force is small and close the valve, and force open the valve, the diameter of the stem can be reduced accordingly. The same time, the role of media, this form of valve more closely. Our valve "three to" has been provided, and closing the valve the flow of all top-down. Cut-off valve is opened, the valve opening height is the nominal diameter of 25% to 30%, the flow has reached the maximum, indicating that the valve has reached the fully open position. Cut-off valve fully open position, the stroke of the valve should be to decide. 
 Cut-off valve has the following advantages: a simple structure, manufacturing and maintenance more convenient. (2) the working stroke is small, open and close a short time. Good sealing, small friction force between the sealing surface, longer life expectancy. 
 Shortcomings of the cut-off valve is as follows: 1. Fluid resistance, the larger force required to open and close. (2) does not apply to particles with a high viscosity, easy to coking media. Adjust the performance is poor. 
 Cut-off valve structure: (1) the type of cut-off valve stem threads to the location of points and external thread, internal thread. The flow of the medium, straight-through, DC type and angle type. Globe valve seal the form of points, packing seal globe valves and bellows sealed stop valve. Straight-through, DC and rectangular Type (2) closing the valve body structure. Straight-through processing is the most common structure, but its resistance to fluid. DC fluid resistance is small, used for containing solid particles or fluid viscosity. The use of forged right angle body, applies to a small pass through the higher pressure cut-off valve. 
 Installation and maintenance of the cut-off valve should note the following: a hand wheel, lever operated stop valve can be installed in any position on the pipeline. Handwheel, handle and Wei mechanism, does not allow for lifting with. 3, the flow of media should be consistent with the body shown in the arrow direction. 
 Pao-teh, cut-off valve has been widely used in a variety of boiler steam system, minerals, petroleum, chemicals, liquefied gas, water supply and drainage, food, pharmaceutical, power generation, urban construction, municipal, and other fields, as well as residents' daily lives. Pao-teh, products sold throughout the country, high quality, efficient service, won the trust of users and the widespread praise.
