Choke Valve

Cameron’s control choke valves are designed to provide precise flow control throughout their entire operating range, with a well-proven track record in the field:

The plug and cage control choke uses the plug as the controlling element and throttles the flow on the internal diameter of the ported cage. The ports in the cage are sized and arranged to give the most appropriate combination of control and flow capacity for each application.

A major consideration when sizing the choke is the ability to closely manage well startup while optimizing capacity toward the end of well life to maximize production.

The plug and cage design is highly optimized and incorporates the largest-possible flow area, making it ideal for high-capacity applications. Plug and cage chokes also are constructed with a solid tungsten carbide plug tip and inner cage for extended resistance to erosion. These valves may further be configured with a solid tungsten carbide wear sleeve in the outlet of the body to provide enhanced protection in sandy service.


  • Large visual indicator provides position in 1/64-in (bean) as standard.
  • External grease port lubricates threads and bearings.
  • Stem lock maintains set position.
  • Bleed plug assembly vents pressure before disassembly.
  • Antirotation key translates rotation from the drive bushing into linear movement of the lower stem/flow plug assembly.
  • Two-piece stem is threaded and locked and is removed from wellbore fluids. 
  • Large annulus area reduces the risk of body and trim erosion caused by high velocities.

All control chokes are available in manually operated or actuated models. Custom-designed trim components to suit a wide variety of Cv capacities and flow characteristics also are available.

HT Choke

Cameron HT-rated chokes are a tried-and-true flow control solution for all heavy oil recovery operations, including steam-assisted gravity drainage (SAGD) and cyclic steam stimulation (CSS), and are dedicated to high-temperature duty.

Control chokes, the gold standard in flow control technology, have been an essential part of wellhead and production machinery for more than 30 years. Whether it’s for injection or production, SAGD or CSS, the plug & cage trim design provides constant performance. Our HT chokes offer numerous trim capacities and flow characteristics for each nominal choke valve size, as well as durability, impact protection, corrosion resistance, and precise controllability.
