Gate Valves – Cast Steel And Ductile Iron Materials

TWT Valves is a prominent manufacturer and supplier based in China, renowned for its exceptional products. Over the years, we have successfully delivered comprehensive valve solutions for significant projects both domestically and internationally.

The main difference between gate valves made of cast steel and ductile iron lies in the materials used for their construction.

1. Cast Steel Gate Valves:

They are manufactured using cast steel, which is a type of carbon steel that undergoes a casting process.

Cast steel offers excellent strength, durability, and resistance to high temperatures and pressures.

These gate valves are known for their robust construction, making them suitable for handling corrosive fluids, high-pressure systems.

Cast steel gate valves are commonly used in industries such as oil and gas, petrochemical, power generation, and refining.

2. Ductile Iron Gate Valves:

They are made from ductile iron, also known as nodular cast iron or spheroidal graphite iron.

Ductile iron provides a combination of strength, ductility, and corrosion resistance. It is more flexible and has a higher impact resistance compared to traditional cast iron.
