The difference between stainless steel ball valve and cast steel ball valve.

Stainless steel ball valves and cast steel ball valves are two common types of ball valves. They have certain differences in appearance, material, use, price, etc.

First of all, the materials of stainless steel ball valves and cast steel ball valves are different. The main material of stainless steel ball valve is stainless steel, which has the advantages of corrosion resistance, high temperature and high strength. It is suitable for fluid control in various chemical, food, environmental protection and other industries. The cast steel ball valve is made of cast steel, which has strong pressure resistance and impact resistance, and is suitable for fluid control in large-scale petroleum, chemical industry, electric power and other industrial fields.

Secondly, the structures of stainless steel ball valves and cast steel ball valves are different. Stainless steel ball valves usually adopt a straight-through structure, with small size, small flow resistance and large flow capacity, and are suitable for general fluid control. The cast steel ball valve adopts a large structure and is suitable for the control of large pipelines and high-pressure fluids.

In addition, the prices of stainless steel ball valves and cast steel ball valves are also different. Stainless steel ball valves are generally more expensive than cast steel ball valves because stainless steel is more difficult and costly to process.

When choosing stainless steel ball valves or cast steel ball valves, the choice should be based on the specific application. For example, in the food, pharmaceutical and other industries, stainless steel ball valves must be selected to ensure the hygiene and safety of the fluid. In large-scale petroleum, chemical, electric power and other industries, cast steel ball valves have more advantages because of their high strength, pressure resistance and impact resistance.

In general, stainless steel ball valves and cast steel ball valves each have their own advantages and scope of application, and should be selected according to specific application conditions. When selecting, factors such as the nature of the fluid, pressure, and temperature must also be considered to ensure that the selected ball valve can meet the usage requirements.
