1. Different working principles

Copper valve: The ball valve is mainly used to cut off or connect the medium in the pipeline, and can also be used for the regulation and control of the fluid. Strong shearing force, especially suitable for media containing fibers and tiny solid particles.

Stainless steel valve: The working principle of the ball valve is to make the valve unblocked or blocked by rotating the valve core. The ball valve switch is light, small in size, can be made into a large diameter, reliable sealing, simple structure, convenient maintenance, the sealing surface and the spherical surface are often closed, and are not easily eroded by the medium, and are widely used in various industries.

2. Different materials

Copper valve: The material used is mainly composed of copper.

Stainless steel valve: The material used is mainly composed of stainless steel.

3. The temperature of the working environment is different

Copper valve: If the temperature of the working environment medium exceeds 80 degrees, a copper valve must be used.

Stainless steel valve: If the working environment medium temperature does not exceed 80 degrees, stainless steel valve can be used.

4, the price is different

Copper valve: the cost of materials is relatively expensive.

Stainless steel valve: The cost material is cheaper than copper valve.

5. Different applicable substances

Stainless steel valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media;

Copper valves are suitable for general working media such as water, solvent, acid and natural gas, and are also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene.
