Metal Ball Check Valve

A ball check valve, a type of mechanical valve used in fluid control systems, comprises several key components. At its core is a spherical or ball-shaped disc that moves within the valve body to regulate fluid flow. This ball rests on a sealing surface known as the seat, creating a tight seal to prevent backflow. The valve body features inlet and outlet ports, where fluids enter and exit. A stem or shaft is connected to the ball and controls its movement, often with the assistance of an optional actuator like a lever or motor, especially in larger or automated systems.
