1. The valve body is precision cast using QT450-10 material that is better than the national standard. The tensile strength is 450Mpa, the elongation rate is greater than 10%, and it is not easy to crack or freeze. The spheroidization rate is above level 3, fully in line with the mechanical properties of QT450.


2. The inside and outside of the valve body are electrostatically coated with powder epoxy resin, and the spray thickness reaches 250μm, which effectively prevents corrosion and rust caused by contact between the valve body and the medium, and has a beautiful appearance.
