Product Description
DIN3352-F4 NRS Brass Gland Resilient Seated Gate Valve, DN50-DN600
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.
