Control Valve Corrosion & Chemical Compatibility: A Complete Guide

What is chemical compatibility?The wetted parts of valves may be constructed from a number of materials:Metals (for example: cast iron, stainless steel, nickel alloys) for casings and other components where mechanical strength is important.Thermoplastics (for example: PTFE,PFA,FEP) for casings, linings, bearings, gaskets and seals when dealing with corrosive chemicals.
