Polyvalve | Rugged and reliable Poly-Gas valves for Natural Gas

Why use Poly-Gas^® Valves?

Polyvalve Poly-Gas^® valves are everything you’d expect from the company that invented Polyethylene valves.

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

Rugged and reliable Polyvalve Poly-Gas^® valves are the strongest part of a Polyethylene piping system.
No metal internal parts.
Bubble-tight shutoff from dual elastomeric seats.
Fused body shell eliminates leak paths to atmosphere.
High-grade polymeric materials eliminate corrosion.
Multiple elastomeric stem seals.
Smooth bore gives excellent flow characteristics in both full and standard port designs.
