 Stainless steel cut-off valve J41W-16P-of DN50 Overview: 

 Opening and closing pieces of stainless steel globe valve J41W-16P-of DN50 plug-shaped valve, seals appear before the plane or cone, the valve in a straight line along the center line of the fluid. Stem form 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 stainless steel globe valve only applies to the fully open and fully closed, is not allowed to make adjustments and to reduce expenditure. 

 The stainless steel globe valve J41W-16P-of DN50 valve R & D and production of strong German forces sealed valve, the valve is closed the valve to exert pressure 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, the emergence of self-sealing valve, stainless steel globe valve the flow of media reform from the top of the valve into the valve chamber, then in the medium pressure, the force is small and close the valve, while a large force to open the valve diameter of the valve stem can be reduced accordingly. The same time, the role of media, this form of valve more closely. China's valve "three to the provisions of the flow of stainless steel globe valve, should be used from top to bottom. Stainless steel cut-off valve open, the valve opening height for the nominal diameter of 25% to 30% when the flow has reached the maximum, indicating that the valve has reached the fully open position. Stainless steel globe valve fully open position, the stroke of the valve should be to decide. 

 The stainless steel globe 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. 

 The disadvantage of stainless steel globe valve as follows: 

 A 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. 

 Stainless steel globe valve structure: 

 (1) the type of stainless steel globe valve stem threads to the location of points and external thread, thread type. The flow of the medium, straight-through, DC type and angle type. Stainless steel globe valve according to the sealed form of points, packing seal, stainless steel cut-off valves and bellows sealed stainless steel globe valve. 
 2 stainless steel globe valve, the valve structure straight-through, DC and rectangular type. 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 high pressure stainless steel globe valve. 

 Installation and maintenance of stainless steel cut-off valve should note the following: 

 A hand wheel, lever operated stainless steel globe 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.
