Polyethylene Natural-Gas Valves Designed With Finite-Element Analysis

In response to a growing industry trend toward corrosion- and maintenance-free natural-gas valves, Kerotest designed POLYBALL™™ 1/2" to 12" standard- and full-port valves made of medium- and high-density polyethylene. The valves also had to meet or exceed ASME B16.40, ASTM D-2513, and the U.S. Code of Federal Regulations (CFR), Part 192 standards.
