Flow ControlNordstrom ValvesWhy use Flowserve Nordstrom Poly-Gas Valves?Nordstrom Poly-Gas valves are everything you’d expect from the company thatinvented polyethylene valves.More than two million Nordstrom Poly-Gas valves have been sold since1976 and are in use throughout the world. Here’s why: Rugged and reliable NordstromPoly-Gas valves are thestrongest part of a polyethylenepiping system. Bubble-tight shutoff fromdual elastomeric seats. Fused body shell removes leakpaths to atmosphere. High-grade polymeric materialseliminate corrosion. Multiple elastomeric stem seals. No metal internal parts. Smooth bore gives excellent flowcharacteristics in both full andreduced port designs.2" – 12" design½" – 2"Polyvalve II (C-style) designNote: Has high-strength stainless steel stem. 2" C-style is reduced bore only.NORDSTROM POLY-GAS VALVES FOR NATURAL GAS

May suffer damage from ground movement. Leaks may occur where the polyethylene and metal meet. Requires cathodic protection for each metal valve to prevent corrosion.FUSIONAll-Polyethylene Systems: Intrinsically safe. Pipe is fused to the valves so there are no leak points. No chance of corrosion. Little chance of rupture because polyethylene systems flex when the ground moves.NORDSTROM POLY-GAS VALVES FOR NATURAL GASFUSION
