A brass ball valve is an alloy of copper and zinc. If the brass is only made up of copper and zinc, it is called plain brass. Brass is often used in the manufacture of valves, water pipes, connecting pipes for internal and external air conditioning units and radiators.
Brass ball valves are made of cast iron, brass, carbon steel, stainless steel, alloy steel, PVC, ABS, and other materials, brass ball valves are generally used for household water pipes or gas pipes on low-pressure small diameter valves, the manufacturing process is simple, inexpensive, brass than the price of steel is high, lower than the price of stainless steel.
The brass ball valve is an evolution of the plug valve. It has the same rotating 90-degree action, the difference is that a ball valve is a sphere with a circular through hole or passage through its axis. The ratio of the sphere to the passage opening should be the same. That is, when the ball is rotated 90 degrees, it should have all spherical surfaces at the inlet and outlet, thus cutting off the flow. The ball valve can be closed tightly with only 90 degrees of rotation operation and very little rotating torque. The completely equal valve body cavity provides the medium with very little resistance and a straight flow path.
Features: The main feature of the ball valve is its own compact structure, small fluid resistance, full diameter ball valve basically no flow resistance. Seal reliable, simple structure, small volume, lightweight, easy maintenance, sealing surface and the spherical surface is often in a closed state, not easy to be media erosion, easy to operate and repair, suitable for water, solvents, acids, and natural gas and other general working media, but also for harsh working conditions, such as oxygen, hydrogen peroxide, methane, and ethylene, etc., various industries are widely used, fully open or fully closed, the ball and seat sealing surface and When fully open or fully closed, the ball and seat sealing surface is isolated from the medium, the medium will not cause erosion of the sealing surface of the valve when it passes through, the range of application is wide, the passage diameter is from small to a few millimeters, large to several meters, from high vacuum to high pressure can be applied. The ball valve body can be integral or combined.
Application:
The brass ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. The ball valve designed as a V-shaped opening also has a good flow adjustment function. Used in chemical, petrochemical, petroleum, paper, mining, power, liquefied gas, food, pharmaceutical, water supply and drainage, municipal administration, mechanical equipment, electronics industry, urban construction and other fields.
