API 6A High-Pressure Choke Valve | Adjustable & Positive Flow Control

Precision Flow Regulation for Demanding Oilfield Wellhead and Manifold Applications

Our API 6A Choke Valve is a critical flow-control component engineered for high-pressure oil and gas production systems. Designed to regulate fluid flow rate and downstream pressure precisely, these valves are manufactured from premium forged alloy steel and high-grade corrosion-resistant materials to ensure maximum reliability in the most extreme working environments.

Whether you require a fully adjustable throttle for precise metering or a fixed positive choke for constant flow restriction, our API 6A certified choke valves provide the safety, durability, and operational efficiency required for modern wellhead and manifold operations.

Key Features & Design Advantages

Dual Function Options: Available in both Adjustable Choke (with external stem and indicator scales for precise flow trimming) and Positive Choke (with interchangeable fixed-bean inserts for constant pressure drop) configurations.

Superior Corrosion Resistance: Engineered with critical internal trim components (seat, needle, and cage) made from highly resistant materials like Stainless Steel, Inconel, or Hastelloy, ensuring exceptional longevity in sour gas (H₂S) and high-salinity fluid environments.

Visible Position Indicator: Adjustable models feature a clear, rugged external indicator scale that allows operators to monitor the valve's opening position (often in 64ths of an inch) at a glance, enabling precise flow adjustments without guessing.

Robust Forged Construction: The valve body and bonnet are forged from high-strength alloy steel, capable of withstanding extreme pressure fluctuations and mechanical stress in both onshore and offshore applications.

Multiple Connection Interfaces: Designed with versatile end connections to fit into your existing piping seamlessly. Available with API 6A Flanges, Hammer Union connections, or premium Threaded connections.

Industry Certifications: Manufactured in strict compliance with API 6A (including PR1/PR2 performance requirements) and NACE MR0175 standards to ensure global safety and quality acceptance.

Technical Specifications

Adjustable vs. Positive Choke Valves

To better serve your specific operational requirements, we provide both primary types of choke valves:

Adjustable Choke Valve: Ideal for applications requiring variable flow control. An external needle or cage mechanism modulates the flow area. The clearly marked indicator dial allows incremental, step-less adjustments to fine-tune the production rate.

Positive Choke Valve: Designed for fixed or "bean" flow control. It utilizes a replaceable, tungsten-carbide coated flow bean (insert) with a precise hole diameter. This provides a constant choke size, ensuring a specific pressure drop across the wellhead without moving parts, highly recommended for extreme erosive services.

Primary Industrial Applications

Our forged choke valves play a vital role in critical upstream and midstream operations, including:

Wellhead Flow Control: Regulating production rates from oil and gas wells.

Fracturing & Stimulation Manifolds: Controlling high-pressure fluids during hydraulic fracturing operations.

Water Injection Systems: Managing injection pressures and flow rates for Enhanced Oil Recovery (EOR).

Well Testing & Completion: Ensuring safe pressure management during drill stem testing (DST) and well clean-up.
