Flange Connection Globe Valve Carbon Steel
Globe Valve Features
Globe Valve are subject to compulsory sealed valve, so when the valve is closed pressure must be impressed to disc, prevent seal leakage. When the medium from below disc into valve, the operation is to overcome the resistance, which is stem and packing friction force produced by the medium pressure, the close force of the valve is larger than open force, so stem diameter should be large, otherwise it will happen stem bending fault. In recent years, since the valve seal appeared, the flow direction of medium is from upper disc into the body cavity, then above in medium pressure, close the valve force is smaller than open force of valve,the valve stem diameter can be reduced accordingly. At the same time,in effect, the form of the valve is strict.
1) Fluid resistance is great, because body medium channel is tortuous,fluid resistance is large, power consumption is large
2) Medium flow direction when nominal pressure PN≤16MPa,generally uses downstream from disc bottom to upper, when then nominal pressure PN≥20MPa,generallu uses back flow,medium from the upper of the disc to the down. To increase the sealing performance. When using, globe valves medium only single direction,medium can not change flow direction
3) When full open disc often affected by erosion.
