2025 Top 10 WCB Ball Valve Factory in the world

Dec 15, 2025

Introduction to WCB Ball Valve

WCB ball valves are a type of quarter - turn valve used to control the flow of a fluid by means of a spherical disc (the ball). The "WCB" refers to a common cast carbon steel material grade in valve manufacturing. WCB has good strength, toughness, and weldability, making it suitable for a wide range of applications in industries such as oil and gas, chemical processing, power generation, and water treatment.


The ball in a WCB ball valve has a hole (bore) through it. When the valve is open, the bore is in line with the flow path, allowing fluid to pass through freely. When the valve is closed, the ball is rotated 90 degrees so that the bore is perpendicular to the flow path, blocking the fluid flow. These valves are known for their quick operation, tight shut - off capabilities, and relatively low maintenance requirements.
