Control Valves

All Cage Trims are inserted into the PIBIVIESSE High Performance trunnion mounted ball valves. Thus, all Design Features and field proven valve reliability remain as standard.

Design & Features

CAGEBALL™ control ball valves are particularly recommended any time that noise reduction, cavitation control, erosion, hydrate formation, plugging and clogging risk are present or handling of very large flow rates is a challenge for conventional valves.
Another important feature is the large rangeability. One valve can perform the duty of two or even three conventional control valves. The potential savings of building only one single control loop is huge.
These control valves product lines can be further personalized with: Integrated down stream Flow Restrictor, Special silencer or Hyper Silencer trim.
The Hyper-Cage trim is also available; this design combines the high efficiency of the multistage type trim with the Cv of a conventional ball valve allowing, if needed the pigging of the pipeline.
