The Pressure Seal Globe Valves is only suitable for full opening and full closing, and no adjustment and throttling are allowed. The globe valve is a forced seal 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 under the valve, 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 that of the valve, so the diameter of the stem is large, otherwise the valve rod will have the failure of the top bending.
