CMI20 | INLINE DISC CHOKE
Cactus Flow Products
The Cactus Flow Products CMI20 is a three-quarter-turn inline disc choke for accurate, straight-through flow control across a wide service range. Two precision-lapped MOV discs rotate against each other to meter flow, with the three-quarter-turn travel giving finer throttling resolution than a quarter-turn choke.
Diamond-lapped discs seat for reliable shut-off while differential pressure holds them together to steady flow and cut vibration, and an open flow path passes large solids. Tungsten carbide, ceramic, or stainless discs resist erosive, high-velocity flow.
Rated at 5,000 PSI in 1" and 2" sizes, the CMI20 covers standard, NACE sour, high-temperature, and low-temperature service in carbon, alloy, or stainless bodies. Pie, circular, or half-moon flow areas, a replaceable wear sleeve, and threaded, flanged, butt-weld, or socket-weld ends complete the package.
Typical Applications:
Straight-through inline flow control, large-solids and abrasive service, sour (NACE) and high- or low-temperature service, production and flowback operations, and automated choke control.

PERFORMANCE ADVANTAGES
Why the CFP CMI20 Choke Performs Where It Counts
FINER THROTTLING RESOLUTION
The three-quarter-turn travel spreads the flow curve over a longer stroke than a quarter-turn choke, giving finer control at each position. Operators get precision where dialing in exact rate matters.
BUILT FOR A WIDE SERVICE RANGE
Standard, NACE sour, high-temperature, and low-temperature configurations in carbon, alloy, or stainless bodies let the CMI20 match nearly any production environment. One platform covers sweet, sour, hot, and cold service.
DISC TRIM THAT SEALS AND SURVIVES
Diamond-lapped discs flat within two light bands seat for reliable shut-off, and a wiping action keeps the faces clean each stroke. Tungsten carbide or ceramic discs resist the wear of erosive, high-velocity flow, extending service life.
PASSES LARGE SOLIDS WITHOUT PLUGGING
The open, straight-through flow path handles large solids that would lodge in a plug-and-cage trim. That keeps it flowing in dirty, debris-laden service where other chokes foul and stick.
