Full port ball: A full port ball has a diameter that is the same size as the inside diameter of the valve body.
Reduced port ball: A reduced port ball has a smaller diameter than the inside diameter of the valve body, which reduces the flow rate through the valve.
Trunnion ball: A trunnion ball is mounted on trunnions or pivot points, which allows it to rotate and seal against the valve body more effectively.
L-port ball: An L-port ball has a port or opening in the shape of the letter “L”, which allows for a flow pattern that is different from a standard ball valve. L-port balls are often used in diverting or mixing applications.
Floating ball: A floating ball is not attached to a stem or handle and is free to move within the valve body. Floating balls are often used in high-pressure or high-temperature applications where a tight seal is required.
