Globe Check Valve, also known as a shut-off valve, is a forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. When the medium enters the valve from the bottom of the disc, the resistance that the operating force needs to overcome 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. Therefore, the diameter of the valve stem must be large, otherwise, the failure of the valve stem to bend will occur. Next, let's take a look at Globe Valve's operation and moment analysis.
