Ferrule Ball Valve

About product

A ferrule ball valve consists of a hollow ball with a through hole (bore) in the center. The ball has a port or passage that can be aligned with the inlet and outlet ports of the valve body to allow flow or rotated to block the flow.

The valve is operated by a handle or actuator that rotates the ball to control the flow. Marine ferrule ball valves are used in various marine systems, including water and fuel systems, ballast systems, bilge systems, and hydraulic systems. They are also employed in applications such as shipbuilding, offshore platforms, and marine transportation.
