Stop-Ball ball valves are used as shut-off valves in hydronic heating and cooling systems. The straight body design enables easy operation, even when installed at places difficult to reach. Ball valves have a ball with a bore hole inside the valve housing. When the valve is open the medium flows through this bore. When the valve is closed by turning the lever by 90° the ball is turned accordingly. The valve opening is closed as the bore then lies crosswise to the valve opening. The pipeline is shut-off.
