Three-Piece Manual Ball Valve is a fluid control device consisting of three main components: the valve body, the ball, and the actuator. Its defining feature is the three-piece valve body design, which facilitates maintenance and component replacement.
The ball rotates within the valve body, aligning or offsetting its through-hole with the valve's flow passage to control fluid flow. This valve is widely used in industrial piping systems for regulating, isolating, or connecting fluid flow.
