Ceramic valves lower FCCU maintenance costs

Comparisons between metals, sintered ceramic composites and cast ceramics illustrate their ability to handle high temperature, erosive process conditions. Ceramic-based valves provide excellent resistance to erosion and corrosion. The wear resistant advantages of ceramics over metals become more pronounced at higher temperatures. Refractory-lined parts last up to five years in catalyst service while metallic hardfaced parts last one to two years
