OVERVIEW

This ball check valve is a kind of check valves that acts automatically when the flow stops, thanks to the movement of the ball located inside the valve itself, that returns to initial position, stop the flow. The ball check valves grant the full bore with the movement of the ball, without pressure drops. The mechanical work of these check valves creates optimal conditions inside the valve, the passage is never obstructed, and this kind of valve can be well used in case of flow with little powders. The ball check valves don’t need any maintenance and are automatically cleaned.
