Product Description

DIN3352-F4 Gearbox Resilient Seated Gate Valve, DN500-DN1200


Features


  •  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.

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

  •  Stainless steel stem with rolled threads for high strength.

  • The valve can replace stem seals under pressure.

  •  Full bore.

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