Ductile Iron Gate Valve

Ductile Iron Gate Valve is a valve made of ductile iron, widely used in water treatment and petrochemical industries. Its features include high strength, corrosion resistance and wear resistance, and stable operation under high pressure and high temperature conditions. This valve realizes the on-off control of the fluid by lifting the valve plate, and is suitable for occasions that need to be fully opened or closed.
