KV series ball valves working principle

KV series ball valves operate by rotating a valve core to open or close the valve. The core of a ball valve is a perforated ball. When the central axis of this hole aligns with the central axis of the valve's inlet and outlet, the valve is open. When the ball is rotated 90 degrees such that the central axis of the hole is perpendicular to the central axis of the valve's inlet and outlet, the valve is closed.
