Bearing Parts Material
Pressure parts (valve bodies) are directly in contact with the fluid controlled by the valve, and the physical and chemical effects of the medium are the greatest. If the medium fluid is a corrosive chemical substance, it needs to be manufactured with corrosion-resistant materials. If the medium fluid pressure is very high, then the material with poor pressure resistance can not be used as the manufacturing material of pressure parts.
Known: nominal pressure, temperature, medium fluid for water, oil, etc.
So material selection: carbon cast steel (ZG230-450)
