Lever Ballstop Valves

Lever Ballstop Valves

The ballstop valve is a ball valve with an integral check valve to provide isolation and prevent backflow. 

Ballstop lever ball valves have an integrated check valve situated within the ball of the valve, which allows a more compact assembly in a single component compared to a separate ball valve and check valve. Ballstop valves are suitable for use in domestic and small commercial heating systems.
