DIN PN 16 Cast Iron angle globe valve
Angle globe valves belong to forced sealing valves, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak.When the medium from the lower valve disc into valve 6, the operating force to overcome the resistance, is the friction force of the valve stem and packing and the thrust generated by the pressure of the medium, the force of the valve is larger than the force of the valve open, so the diameter of the valve stem to be large, otherwise the valve stem bending fault will occur.From the appearance of the sealed valve, the flow of the globe valve media will be changed from the upper disc into the valve chamber, then under the action of media pressure, the force to close the valve is small, and the force to open the valve is large, the diameter of the valve stem can be reduced accordingly.At the same time, under the action of the medium, this form of the valve is more rigorous.China's valve "three to" has been stipulated that the flow of the globe valve, all adopt from top to bottom.
