Severe abrasive service valves have become a critical component in the design and operation of varied industrial processing plants. Whether it be catalyst, harsh polymers, chemical slurries, waste materials in mining, or the transportation of mineral slurries at low and high pressure, all such applications need cutting edge technology compared to conventional liquid and vapour services.
The modern design of such valves has become more complicated due to the use of highly sophisticated process controls, varying types of process media, increased sizes, higher pressures, and in some cases elevated temperatures. These complexities and variables have specifically challenged valve designers and manufacturers, who need to work closely with the engineering design companies and end-users alike, to find viable, cost-effective and more importantly, reliable solutions.
