Carbon Steel Flanged Ball Valve

About product

The working principle of stainless steel flanged ball valves relies on the rotation of the valve stem to open or close the valve. These ball valves are characterized by their lightweight design, compact size, ability to be manufactured in large diameters, excellent sealing performance, simple structure, and convenient maintenance. The sealing surface and ball surface remain in close contact when the valve is closed, reducing the risk of erosion by the medium. As a result, stainless steel flanged ball valves find extensive applications across various industries.

The main features of stainless steel ball valves include their compact structure, ease of operation and maintenance, suitability for general working media such as water, solvents, acids, and gases, as well as their ability to withstand harsh working conditions with media such as oxygen, hydrogen peroxide, methane, and ethylene. The valve body of a ball valve can be either integral or modular. It is recommended to install this type of valve in a horizontal position within the pipeline.

Product Detail

Advantages of Stainless Steel Flanged Ball Valves:

Low fluid resistance, with a resistance coefficient equal to that of the same length of pipe segment.

Simple structure, compact size, and lightweight design.

Excellent sealing performance. The sealing surfaces of ball valves are commonly made of plastic materials, ensuring reliable sealing even in vacuum systems.

Convenient operation. The valve can be fully opened or closed with just a 90° rotation, enabling easy remote control.

Easy maintenance. Ball valves have a simple structure, and the sealing rings are usually movable, making disassembly and replacement relatively straightforward.

When fully open or fully closed, the sealing surfaces of the ball and seat are isolated from the medium, preventing erosion of the valve sealing surfaces during media flow.

Wide applicability. Ball valves can be used in a wide range of applications, from small diameters to several millimeters to large diameters of several meters. They can handle high vacuum to high-pressure environments.
