The severe service valve market exceeds $10 billion per year and is growing at a rate faster than the general valve market. The repair market, too, is quite large. Over the life of a severe service valve, repair and support revenues can be three times the initial price.
The performance of these valves is required to be closely monitored, and adjustments are made as needed. Oversight and service, which is traditionally undertaken by the manufacturer, are now more commonly being transferred to third parties, including valve suppliers.
