CMI20

Overview

CMI20 Features

The CMI20 uses MOV disc-type trim with a three-quarter-turn rotation from open to close in a straight-through inline body. Accurate control is maintained with Pie, circular, or half-moon (D-shaped) flow areas, while the open flow path allows large solids to pass and helps resist blockage.

Its solid tungsten carbide, ceramic, or stainless steel discs are diamond-lapped within two light bands, plus or minus 0.00002 inch, of flatness to support reliable shut-off. Differential pressure across the trim creates a strong retention force between the discs for accurate flow-rate control and reduced trim vibration, while wiping action helps keep the disc surfaces clean.

• Three-quarter-turn rotation from open to close in an inline body design.
• Available in threaded, flanged, butt weld, and socket weld configurations.
• Pie, circular, and half-moon (D-shaped) flow areas support accurate control.
• Solid tungsten carbide, ceramic, or stainless steel disc components.
• Large-solids passage provides high resistance to blockage.
• Differential-pressure retention helps maintain flow control and reduce trim vibration.
• Wiping action helps reduce trim wear and deterioration.
• The choke outlet spool includes a replaceable outlet wear sleeve.
• Available in manually operated or actuated configurations.
