CLPBB

Bolted Bonnet Plug & Cage Control

CLPBB is a bolted bonnet plug-and-cage choke for high-demand pressure-control applications where larger trim capacity, high Cv, erosion resistance, equal-percentage control, and lower operating torque matter.

Bolted Bonnet Design
2K to 15K API; ASME/ANSI to 1500#
Equal-Percentage Control
Lower Operating Torque

Overview

CLPBB Features

CLPBB uses the same plug-and-cage control concept as CLPB, with an internal plug fastened to the stem that moves axially inside a ported cage. As the plug retracts, it reveals more cage ports and increases the available flow area.

The bolted bonnet design supports the larger .75 to 3.2 trim range while the pressure-balanced flow path helps reduce erosion, turbulence, stem load, and operating torque in high-demand service.

  • Use CLPBB when the job needs bolted bonnet plug-and-cage control with .75 to 3.2 trim size coverage.
  • Pressure-balanced, self-flushing design helps lower operating torque and stem load.
  • Equal-percentage flow characteristic supports controllability and rangeability in demanding conditions.
  • Tungsten carbide trim can support erosive service where sand or wear potential drives the selection.
