The d50 PVC check valve is a standard part of the pool pump’s suction line – it closes automatically when the pump stops and prevents the suction pipe from emptying.
The 50 mm diameter corresponds to the most widespread suction pipe of family pools, making this valve highly versatile.
The PVC body withstands chlorinated water and UV radiation, so it serves reliably both outdoors and in pool plant rooms.
A properly functioning check valve extends the pump’s service life, as it eliminates shock loads at every start.
