What is the difference between copper ball valve and stainless steel ball valve
date:2022-07-21 14:36
The difference between copper ball valve and stainless steel ball valve lies in the following aspects: 1. The materials they use are completely different. The steel ball valve uses copper and the stainless steel ball valve uses stainless steel. 2. The 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, corrosion or wear and high temperature resistance. Generally, stainless steel is more expensive. 3. Under the same pressure environment, the price is cheaper than that of stainless steel, 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. Copper ball valve must be used! If the medium temperature does not exceed 80 ℃. Stainless steel ball valve is enough
The stainless steel ball valve can be closed tightly with only 90 degree rotation and a small rotating torque. The completely equal inner cavity of the valve body provides a small resistance and direct flow channel for the medium. The main characteristics of the ball valve are its compact structure and 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 products, liquid metal and radioactive media. The valve body of ball valve can be integral or combined. This type of valve should generally be installed horizontally in the pipeline.
Classification:
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 rely on the rotating spool to make the valve unblocked or blocked. The ball valve has the advantages of light switch, small volume, large diameter, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are often closed, which is not easy to be eroded by the medium, and 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 a valve.
