Product Details

BS5163 DN50-1200 handwheel/ gearbox Resilients seate Gate valve

Features

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.
