AWWA C509 NRS Resilient Seated Water Gate-Valves
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.
