    ² The ductile iron core is fully vulcanized with EPDM rubber, no iron parts are exposed to the medium and the excellent rubber vulcanization prevents creeping corrosion underneath the rubber.

    ² Guides in the wedge and on the valve body ensure a uniform closure, safe operation ensured as the guides prevent overloading of the stem.

    ² Stainless steel stem with rolled threads for high strength.

    ² The valve can replace stem seals under pressure.

    ² Full bore.

    ² Body inside and outside fusion bonded epoxy coating with excellent corrosion resistant performance.
