PFA - fused solid ball - the 4000 and 3700 Series feature a PFA fused ball that is more durable, less susceptible to accumulating build-up and long lasting than an ordinary unprotected ball. With the help of DuPont™, we developed a process to impregnate PFA 0.008 in into a solid metal ball. An additional 0.004 in is added electrostatically for smoothness. Since the PFA becomes part of the metal, it can't flake, chip or peel off. The corrosion and chemical resistance of PFA has been recognized around the world. With the introduction of this valve we present an affordable (same price as most gate valves) ball valve that will outlast any unprotected metal valve in any use. The lubricity of our PFA ball allows for lower torque ratings in any application, making it easier to turn. PFA is an ingredient commonly branded as Teflon®.
