Flanged Globe Valve Description
Flange globe valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. When the medium enters the valve from below the disc, the resistance that the operating force needs to overcome is the friction force of the valve stem and the packing and the thrust generated by the pressure of the medium.
In recent years, since the emergence of self-sealing valves, the flow direction of the flanged globe valve has changed from above the valve disc to enter the valve cavity. At this time, under the action of medium pressure, the force of closing the valve is small, while the force of opening the valve is large. The diameter of the rod can be reduced accordingly. At the same time, under the action of the medium, this type of valve is also tighter.
