What is the differences between the brass ball valve and stainless steel ball valve ?
1. Different applicable substances
Stainless steel ball valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, muds, oils, liquid metals and radioactive media; copper ball valves are suitable for general working media such as water, solvents, acids and natural gas And, it is also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene.
2.Different media temperatures
In terms of medium temperature, under the same pressure environment conditions, the medium temperature range of copper ball valve is higher than that of stainless steel ball valve. If the medium temperature exceeds 80 ℃, copper ball valve must be used, but if it does not exceed 80 ℃, stainless steel ball valve can.
3.Different corrosion resistance
Copper ball valve has excellent corrosion resistance, switch operation is smooth and labor-saving, and durable. Stainless steel does not cause corrosion, pitting, rust or wear, and is resistant to high temperatures.
4. The working principle is different.
Copper ball valve: The ball valve is mainly used to cut off or connect the medium in the pipeline, and it can also be used for the regulation and control of the fluid. The hard-sealed V-type ball valve has a V-shaped core between the V-shaped core and the metal seat of the hard alloy Very strong shearing force, especially suitable for media containing fibers and small solid particles.
Stainless steel ball valve: The working principle of the ball valve is to open or close the valve by rotating the spool. The ball valve switch is lightweight, small in size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, the sealing surface and the spherical surface are often closed, and it is not easy to be eroded by the medium.
5. Different materials.
Copper ball valve: The material used is mainly composed of copper.
Stainless steel ball valve: The material used is mainly composed of stainless steel.
6, the price is different
Copper ball valve: costly materials are more expensive.
Stainless steel ball valve: cheaper material than copper ball valve.
