Control Seal can do the overhaul of any valve and turn the old valve into
a new one. Original testing procedures are performed to ensure valve functionality. Any other additional testing required by customer is possible. Quality inspection is performed as for a new valve. 

Control Seal offers slip overhaul and revulcanisation for Double Block and Bleed plug Valves in case sealing rubber is damaged by debris, dirt or other conditions.

Spare valve can be installed instead of the overhauled one to prevent plant stop during the overhaul. Spare valve can be delivered as bare stem to reduce cost.
