DIN3352 NRS Brass Gland Socket End Resilient Seated Gate Valve， 63mm-315mm
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.
² Suitable for PVC pipes, easy installation.
