Flanged End Globe Valve

The KOSEN Flanged End Globe Valves is a forced seal valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface to leak. When the medium enters the valve six under the valve disc, the resistance that the operating force needs to overcome is the friction force of the stem and the filler and the thrust of the pressure from the medium. The force of the valve is larger than the opening of the valve, so the diameter of the stem is large, otherwise the valve stem bending will occur.
