Features：
①The 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.
②Guides in the wedge and on the valve body ensure a uniform closure, safe operation ensured as the guides prevent overloading of the stem.
③Stainless steel stem with rolled threads for high strength.
④The valve can replace stem seals under pressure.
⑤Full bore.
⑥Body inside and outside fusion bonded epoxy coating with excellent corrosion resistant performance.
