The ductile iron core is fully vulcanized with drinking water approved EPDM rubber internally and externally. No iron parts are exposed to the medium and the excellent rubber vulcanization prevents corrosion underneath the rubber. Nylon Guides in the wedge and on the valve body ensure a uniform closure regardless of high pressure.
