In highly-corrosive chemical and refining applications where in-line and atmospheric sealing is critical, sleeved plug valves provide essential defense against leaks and fugitive emissions. Because they typically face harsh conditions, repair or replacement is an important consideration. However, before those steps have to be taken, there’s a simple step to make them last longer: tightening the bolts.

Twenty-five years ago, the member companies of the Valve Manufacturers Association of America (VMA) saw a need to promote both safety and quality in valve and actuator repair. As a result, the service operations of VMA members banded together to create the Valve Repair Council (VRC). As part of its mandate to educate manufacturers, rebuilders and customers on the importance of proper service and to provide a forum for an exchange of information, the VRC sponsors events such as this year’s meeting and exhibition in Houston, which was June 5-6.

For many of us in the repair community, this was the reaction when the Environmental Protection Agency (EPA) passed fugitive emissions regulations and valve manufacturers were forced to respond. Until now, we could nonchalantly stay uninvolved in the fracas.

The concepts used in long-term cost of ownership (LTCO) go back as far as the 1700s. However, the label was first used in 1929 when the American Railway Engineering Association introduced a manual for efficiently maintaining or building a railway. That manual noted that “in the event there is a subclass of power, then the total cost of ownership should be multiplied by the ratio of the cost of repairs to the total.”
