Valve with an internal thread 1½ inch
Description
Ball check valves are used to prevent backward flow in the pipe. The flow is stopped by a ball, which is embedded in the valve body to create a seal. The ball valves are designed to allow a full throughout hole, thus avoiding the risk of blocking solid bodies. By turning in the flowing sewage, the ball has the ability to self -cleaning, and therefore the valve or leaks are rarely clogged. Ball check valves are recommended for sewage and rainwater pumping stations and to all media that can carry with them: sand, gravel, pieces of rags, cords, etc.
If the valve is blocked by abnormal sewage content, just unscrew the screws fastening the inspection cover, remove the ball and clean the contents of the valve. Such work should always be done with the pumping station power off. Before removing the inspection cover, check that it is closed over the ball check valve so that the returning sewage from the pipeline does not flood the tank and do not hinder the work of the conservator.
