PIBIVIESSE Top Entry ball valves are manufactured in a wide range of diameters and pressure classes. PIBIVIESSE valves are specified for transmission pipelines, pumping, compression and re-injection units, offshore platforms, onshore terminals, pig traps, measuring stations any critical applications such as subsea installations, cryogenic service in LNG plants, high temperature and abrasive services.
PIBIVIESSE Top Entry valves are full inline field repairable and can be used in any critical service applications where in-situ field reparability 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.
PIBIVIESSE Top Entry valves are sized to withstand external loads from the pipeline even when the bonnet, the ball and the seats are removed for maintenance. The cast body and forged bonnet construction allow the use of various grades of carbon steel, stainless steel and other alloys thus complying with most severe service conditions.
