Adjustable Choke Valve – API 6A / API 16C

DEENPU Adjustable Choke Valve provides precise, repeatable flow and pressure control in well-testing, choke-and-kill, and production service. Designed to API Spec 6A and API Spec 16C, the valve uses a hardened needle-and-seat or cage-type trim to regulate flow rates under high differential pressure while resisting erosion from sand-laden or corrosive fluids.

Available with manual handwheel, hydraulic, or electric actuation, each choke is fitted with tungsten carbide or ceramic trim components for maximum service life. Positive (fixed-bean) versions and interchangeable trim kits are also offered, allowing one valve body to cover multiple flow coefficients.

Key Features

  • Tungsten carbide needle and seat – superior erosion resistance in sandy service
  • Replaceable trim kits – one body covers multiple Cv ranges
  • Precise throttling with graduated position indicator (0–100%)
  • Non-rotating stem tip minimizes seat galling during fine adjustment
  • Metal-to-metal body-bonnet seal; no elastomers in pressure boundary
  • Hydraulic or electric actuator packages with position feedback for remote operation
  • Interchangeable with major OEM choke valves (Cameron H2, FMC, etc.)

Applications

  • Well testing and flowback – controlled drawdown of reservoir pressure
  • Choke and kill manifolds – well-control circulation per API 16C
  • Production manifolds – sustained flow-rate regulation
  • Gas lift and injection well service
  • HPHT and sour (H2S/CO2) environments with appropriate material class

Ordering Information

Please specify: nominal size, working pressure, end connection type, trim type and material, actuation method, material class, and required PSL/PR level. Spare trim kits (needle, seat, stem packing) are stocked for fast delivery.
