What is the difference between copper ball valve and stainless steel ball valve

view :

The difference between copper ball valve and stainless steel ball valve lies in the following aspects: 1. They use completely different materials. The steel ball valve uses copper, and the stainless steel ball valve uses stainless steel. 2. Copper ball valve has good corrosion resistance, smooth and labor-saving switching operation, and is durable without leakage. Stainless steel will not produce corrosion, pitting, rust or wear and is resistant to high temperatures. Generally, stainless steel is more expensive. 3. Under the same pressure environment, the price of stainless steel is cheap, and the medium temperature of copper ball valve is much higher than that of stainless steel ball valve if the medium temperature is too high. The copper ball valve must be used! If the medium temperature does not exceed 80 ℃. Use stainless steel ball valve

The stainless steel ball valve can be closed tightly with only 90 degree rotation operation and small rotation torque. The completely equal inner cavity of the valve body provides a straight flow passage with little resistance for the medium. The main characteristics of the ball valve are its compact structure, easy operation and maintenance. The stainless steel ball valve 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. The valve body of the ball valve can be integral or combined. This type of valve shall be installed horizontally in the pipeline.


Stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve. Stainless steel ball valves are made of 304316321 stainless steel ball valves.

Stainless steel ball valves can be unblocked or blocked by rotating the valve element. The ball valve is light to open and close, small in size, can be made into a large diameter, reliable in sealing, simple in structure, and convenient in maintenance. The sealing surface and spherical surface are often closed, and are not easy to be eroded by the medium. It is widely used in various industries. Only its closing part is a sphere, which rotates around the center line of the valve body to open and close the valve.
