You should ask the valve supplier about this; there are quite a few people on our chemical forum who promote valves, so ask them
A check valve, and also a filter
Reply to 3# arita: Can a filter hold that much dirt? What kind of filter is it? Won’t installing it block the entire sewer system?

Check valve – For this as well, it’s necessary to understand your specific requirements!
Just add a filter behind the check valve – if you place it in front, it will definitely cause blockages. By putting the filter behind the check valve, the returning water can be filtered, which also helps to maintain the seal of the valve and prevents blockages
Automatic sludge discharge filters – check online for more information. It definitely will work
Just fabricate a pipe outlet flap by yourself, that’s it :)
Reply 1# shglpv: Ball valves are specifically used in sewer pipes for waste discharge, etc
Reply to 4# shglpv: This parameter was provided by you; you need it otherwise it will be difficult to choose the valve
