The check valve with steel spring PVC S6 d50 prevents undesirable backflow of water in pool pipework with a diameter of 50 mm. The stainless steel spring ensures rapid and reliable closure even at low operating pressure.
The PVC-U valve body resists chlorine and the chemical additives of pool water. The S6 construction series is proven in pool and industrial practice for its reliability and long service life. The valve is designed for solvent-welded installation into DN50 pipework.
It is typically installed downstream of the pump or in the suction branch of the filtration system, where protection against backflow and hydraulic shock extends the service life of the entire pumping unit.
