ORDER CODE DEFINITION
* Required fields
Tecval VB-20 3-Pieces Ball Valve is a Forged Body design. The forging process reduces the surface porosity and closes up internal cavities. The result is mechanical stronger and more durable product, especially suitable for working in high corrosive environment. They are manufactured under ASME B16.34.
