Do you want to want to know what is a brass ball valve and how it works? we're one of the most professional manufacturers of brass ball valves in China, we're glad to share details in following article.
1. What is a brass ball valve
Brass ball valve is a type of brass valve what consisted with a brass ball inside of, brass is an alloy composed of copper and zinc, often used to make brass valves, water pipes, connecting pipes for internal and external air conditioners, and radiators.
Brass ball valve is operated by valve handle which connected to the brass ball, ball rotating will open and close the flow port in brass ball valve.
2. How a brass ball valve works
The brass ball valve evolved from the stop valves. Its opening and closing part is used as a ball, which rotate 90 degree around the axis of the valve stem to achieve the purpose of opening and closing.
3. Why should brass ball valve be made of brass
The materials for manufacturing ball valves are cast iron, brass, carbon steel, stainless steel, alloy steel, PVC, ABS and other materials. Brass ball valves are generally low-pressure small-diameter valves used on household water pipes or gas pipes. The manufacturing process is simple and cost is low.
Brass has high strength, high hardness and strong chemical resistance. The mechanical properties of cutting are also outstanding. Brass has strong wear resistance.
4. The functions of brass ball valves
The brass ball valve is mainly used for cutting off, distributing and changing the flow direction of the medium in the pipeline. The V-shaped opening ball valve also has a good flow adjustment function.
The main features of the ball valve is its compact structure, low fluid resistance, and the full-bore ball valve basically has no flow resistance. Reliable seal, simple structure, small size, light weight, convenient maintenance, sealing surface and spherical surface are often closed, not easy to be eroded by the medium, easy to operate and maintain, suitable for general working media such as water, solvent, acid and natural gas, and It is also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc. It is widely used in various industries. When fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium. When the medium passes, it will not cause The erosion of the valve sealing surface has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure. The ball valve body can be integral or combined.
5. The classification of brass ball valves
According to the ball support method, brass ball valves are divided into floating ball valve and fixed ball valve.
Floating brass ball valve: Its main feature is that the ball has no support shaft and the ball is supported by the valve seats at both ends of the valve inlet and outlet. The valve stem and the ball are movable linked, so the ball of the ball valve is clamped by the two valve seats in a "floating" state.
Fixed brass ball valve: Its characteristic is that the ball is connected with the upper and lower stems into one body. The ball can rotate freely along the axis perpendicular to the valve channel, but cannot move along the channel axis. Therefore, the fixed ball valve has small torque, small valve seat deformation, stable sealing performance, long service life, and is suitable for high pressure and large diameter occasions.
6. The applications of brass ball valves
Brass ball valves are widely used in chemical, petrochemical, petroleum, paper-making, mining, electric power, liquefied gas, food, pharmaceuticals, water supply and drainage, municipal administration, mechanical equipment, electronic industry, urban construction and other fields.
The Bottom Line
We have discussed what is a brass ball valve, how it works, main features, all these information will help to understand brass ball valve better and also be useful to select brass ball valves China.
