Swing check valve ductile iron (WHP), flanged

Swing check valve in ductile iron with a flanged connection, intended for use on water and waste water. We call this valve WHP - Water Hammer Protector, as this valve reduces water hammers. With the help of a bypass, this valve can handle both the under pressure and over pressure phase when a water hammer sequenze occurs. The body has a tilted seat for best tightness at low differential pressures. The valve is equipped with a lifting device which makes it possible to drain the pressure side before service. The flap is reversible and comes with NBR or EPDM rubber (KTW, W270, WRAS). Face-to-face length acc. to EN 558-1 basic series 48. Manufactured and tested acc. to EN 1074-3 and resilient seated acc. to EN 12334.
