Stainless steel globe valve is made of stainless steel. Its opening and closing parts are plug-shaped valve disc. The sealing surface is flat or conical. The valve disc moves in a straight line along the center line of the fluid. The movement form of the valve stem also has the lifting and rotating rod type. The stainless steel globe valve is only suitable for full opening and full closing, and it is not allowed to adjust and throttle.            

Stainless steel globe valve is a kind of forced sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve from the bottom of the stainless steel globe valve disc, the resistance to be overcome by the operating force is the friction between the valve stem and packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the diameter of the valve stem should be larger, otherwise the valve rod top bending fault will occur.   

The flow direction of the medium is changed from the upper part of the valve disc into the valve chamber. Under the action of the medium pressure, the force to close the valve is small, but the force to open the valve is large, so the diameter of the valve stem can be reduced accordingly. At the same time, under the action of medium, this type of valve is also more tight.           

The stainless steel globe valve should be installed horizontally. When the globe valve is opened, when the opening height of the valve disc is 25% - 30% of the nominal diameter, the flow has reached the maximum, indicating that the valve has reached the full open position. Therefore, the full open position of the globe valve should be determined by the stroke of the disc.
