BST's B2 flow control chokes are easy to repair by replacing the trim module and associated parts without removing the choke body from the wellhead or flow line.
The unique trim module assembly can be removed as a unit, and a new or factory rebuilt module (with a new seat, stem, and all seals) installed in just a few minutes, greatly minimizing down time.
All complete trim repair and resizing kits include a matched stem and seat, two PTFE jacketed self-energized seals to seal the stem to the bonnet, and the two Viton O-rings required to seal the bonnet to the body and the seat to the body. You can calculate the liquid or gas flow for any trim size (or percentage thereof) at BST's flow calculator web pages.
All kits and parts offered on this page are rated for both standard (sweet) and H2S (sour) oil and gas service per NACE MR-01-75. Viton O-rings are standard, with Aflas as a premium option.
