Product introduction
The opening and closing parts of Ductile Iron Valve Castings are the gates, the direction of movement of the gate is perpendicular to the direction of the fluid, and the bright stem gate valve can only be fully open and fully closed. The main material of this valve is ductile iron, which is light and strong, with small flow resistance and good valve rigidity. And overcome the general gate valve poor sealing, seepage, and leakage of hidden defects has their own unique advantages.
Ductile Iron Valve Castings obtains ductile ink through spheroidization and conception treatment, which effectively improves the mechanical properties of cast iron, especially plasticity and toughness, thus obtaining higher strength than carbon steel. In addition, its light weight, good toughness, and impact resistance have been resistant to high and low temperatures, so it is widely used in some key parts of machinery, such as crankshafts, valves, and pipes.
