Valve selection for abrasive mediums can be a difficult task because it is important to select the best valve style with the longest mean time between failure (MTBF). Some valve types will require extensive modifications to be capable to survive in an abrasive environment where other types of valves are made specifically for abrasive environments. In some industries, the drive for standardization may be challenged in those processes where abrasive mediums exist. To have one valve type to handle all applications in process plant may be a poor and costly decision. All of the modifications required to make a standard valve fit or survive in an environment where abrasive slurries exist may drive the cost of the valve up exponentially. After all of the cost and modification work on the valve is done, it may not have the lowest total cost of ownership (TCO) when compared to a valve that is made specifically for abrasive environments. Companies strive for standardization for many reasons such as decreased training requirements, commonality of spare parts and lower costs due to increased consumption from one supplier or manufacturer. However, modifying a standard product significantly may negate the advantages of decreased training, commonality of spare parts and cost savings. Also, availability of special replacement parts required for these modified products may not be readily available.
