Why use Poly-Water® Valves?

Polyvalve Poly-Water® valves are everything you’d expect from the company that invented polyethylene valves.

Millions of Polyvalve Poly-Water® valves have been sold since 1976 and are in use throughout the world. Here’s why:

  • Rugged and reliable Polyvalve Poly-Water® valves are the strongest part of a polyethylene piping system.
  • Drop-tight shutoff from dual elastomeric seats
  • Fused body shell removes leak paths to atmosphere.
  • Multiple elastomeric stem seals.
  • No metal internal parts.
  • High-grade polymeric materials eliminate corrosion.
  • Smooth full bore gives excellent flow characteristics in both full and standard port designs.
  • Wide variety of trim for your specific application.
  • Flanged end configuration available.
All Metal System (Welded or Bolted):
  • Subject to external corrosion, internal scaling and damage from ground movement.
  • Too-rigid pipe can rupture during frost heave or heavy pressure in hot weather.
  • 30% of all system water is lost to leaks.
Polyethylene Pipe-to-Metal Valve Installation:
  • Subject to the inherent weakness of combining incompatible materials.
  • Vulnerable to ground movement during extremes of cold or heat.
  • 30% of all systems water is lost to leaks.
All-Polyethylene Systems:
  • Intrinsically safe—the valve is an integral part of the pipe.
  • No leak points.
  • No chance of corrosion.
  • Flexible polyethylene systems are less susceptible to ground movement.
