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.
