Since the emergence of self-sealing valves, the medium flow direction of the stainless Globe Check valve has changed from above the disc to enter the valve chamber. At this time, under the action of medium pressure, the force to close the valve is small, but the force to open the valve is large, and the diameter of the valve stem can be adjusted accordingly reduced. At the same time, under the action of the medium, this form of stopcock is also tighter. In addition, the inflow direction of Globe Valve is generally top-down. When the Globe Valve is opened, the opening height of the slice is 25 to 30 of the nominal periphery. The inflow has reached the outside, indicating that the stopcock has reached the completely open position. Thus, the completely open position of the Globe Valve should be determined by the stroke of the stopcock slice. Next, let's take a look at the applicable knowledge of Globe Valve.
