Stop Silent SL13® (formerly Light) stands out from other check valves by its ingenuity. Our check valve can be inserted into the inspection shaft without any additional work, which is far from negligible in terms of cost.

Many of our customers carry out the installation themselves, following the instructions in our installation manual.
