LSS offers valve exchange programs to avoid costly transportation and down-time. The reconditioned valves are sent to location before the problem valves are taken out of line. The problem valves are sent to the dock for us to pick up. Only repairs will be charged.  If the valve is deemed un-repairable it will be sold at an approved price. The client inadvertently is utilizing its own inventory, because this alleviates the need to purchase equipment.
