General Description

The Adjustable Angle Choke Valve is a critical component used in oil and gas wellhead assemblies (Christmas trees) and kill/choke manifolds. Its primary function is to regulate and control the flow rate and pressure of produced fluids (oil, gas, and water) from the well . By manually turning the handwheel, the stem advances or retracts a tapered needle or plug relative to a seat, precisely varying the flow area. This model features a robust angle body design (90°) which inherently provides erosion resistance by directing flow away from the sealing surfaces .

Applicable Standards & Specifications

  • Design & Manufacture: API Spec 6A (Specification for Wellhead and Christmas Tree Equipment)
  • Additional Design: API Spec 16C (Choke and Kill Systems)
  • Flange Connections: API 6A (6B / 6BX Flanges)
  • Testing: API 6A / API 16C (Hydrostatic and Gas testing)
  • NACE Compliance: NACE MR0175 / ISO 15156 (for H₂S service – optional)

Key Features & Applications

Key Features:

  • Precise Flow Control: Allows fine-tuning of flow rates and pressures through a linear or equal percentage characteristic.
  • Erosion Resistance: The hardened trim (Tungsten Carbide/Stellite) withstands the destructive forces of high-velocity, solids-laden fluids .
  • Angle Pattern Design: The 90-degree body design helps protect the stem and sealing area from direct impingement of flow media, extending valve life .
  • Visual Indication: A protected position indicator on the bonnet shows the exact opening percentage of the valve .
  • Interchangeable Trim (Optional): Some models allow conversion between adjustable and fixed choke modes by changing the internal nozzle.

Main Applications:

  • Wellhead Christmas Trees: Regulating production from oil and gas wells .
  • Kill and Choke Manifolds: Controlling well pressure during drilling and workover operations .
  • Flow Lines: As a primary control valve for flow rate and pressure reduction.
  • Test Separators: Controlling flow into testing equipment.
