A blowdown globe valve, also known as the cut-off valve, is a forced sealing valve. Today we mainly introduce the classification and principle of blowdown globe valves.

Globe Valve refers to a stopcock in which the closing member moves along the centerline of the seat. According to the movement form of the slice, the change of the harborage of the stopcock seat is commensurable to the stroke of the slice. Because the opening or ending stroke of the stopcock stem of this type of stopcock is fairly short, and it has a veritably dependable cut-off function, and because the change of the stopcock seat opening is commensurable to the stroke of the stopcock slice, its veritably suitable for inflow adaptation. Thus, this type of stopcock is veritably suitable for cut-off or regulation and throttling. Next, let's take a look at the selection principles and characteristics of a stainless Globe Check valve.

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.
