PIBIVIESSE Top Entry valves are full inline field repairable and can be used in any critical service application where in-situ field repairability and quick turnaround are needed. Thanks to this characteristic, Top Entry Valves can also be welded directly onto the pipeline still allowing easy maintenance operation.
