4-1/16″-3000PSI Adjustable Angle Choke Valve

Technical Data Sheet: 4-1/16″-3000PSI Adjustable Angle Choke Valve

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 .

Dimensional Data (Approximate)

Note: Dimensions may vary by manufacturer. For exact installation dimensions, please consult the specific manufacturer’s GA drawing.

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.
