API 6A Positive Choke Valve – 1-13/16" 10M (10,000 PSI) | 1" Maximum Orifice

The 1-13/16" 10M (10,000 PSI) API 6A Positive Choke Valve with a 1" maximum orifice is a high-integrity, heavy-duty flow regulation component engineered to control pressure and fluid velocity in extreme high-pressure upstream environments. Designed specifically for production manifolds, choke and kill systems, and well testing layouts, this positive (fixed) choke valve utilizes interchangeable internal choke beans to establish a precise, unchanging flow restriction. This ensures predictable wellbore management and excellent protection for downstream equipment.

In high-pressure oil and gas operations, regulating flow using a fixed orifice is preferred when a constant flow rate is required over extended periods. Unlike adjustable chokes which can drift or experience localized wear on the needle and seat, a positive choke forces abrasive, sand-laden fluids or high-velocity gases through a rugged, hardened choke bean. This specific model features a large 1" maximum orifice capacity, allowing field operators to install standard choke beans up to 64/64ths of an inch to match precise reservoir performance requirements.

Manufactured from premium forged alloy steel, this choke valve features a robust bonnet assembly that allows for fast, safe bean changeouts during routine maintenance. It conforms strictly to API Specification 6A dimensional, metallurgical, and performance standards, ensuring absolute containment of severe 10,000 PSI line pressures.

Features & Benefits

• Fixed Flow Precision: Relies on interchangeable, hardened choke beans to maintain an exact, tamper-proof flow rate and pressure drop across the manifold.

• 10,000 PSI API 6A Rating: Built specifically to manage extreme upstream pressures, safely handling a continuous 10,000 PSI (10M) working pressure.

• 1" Maximum Orifice: Accommodates a wide range of standard choke beans up to a full 1-inch diameter (64/64"), offering versatile flow-tuning capacity.

• Heavy-Duty Forged Construction: Forged from high-strength alloy steel to withstand severe erosive wear, mechanical vibration, and internal shock loads.

• Rapid Bean Replacement: Engineered with an easily accessible bonnet closure mechanism, reducing downtime during bean inspections and configuration changes.

Specifications & Technical Details

Applications

This 1-13/16" 10K positive choke valve is a critical asset for surface flow control arrays requiring dependable, fixed-rate regulation. Typical applications include surface production choke manifolds, high-pressure well testing packages, fracturing flowback lines, cleanout manifolds, and injection lines where a permanent, drift-free pressure drop is required.

Quality Assurance

All our API 6A choke valves are manufactured to exact tolerances and subjected to strict quality control processes. The forged steel bodies undergo rigorous non-destructive testing (NDT), dimensional verification, and high-pressure hydrostatic shell and seat testing to guarantee absolute containment at maximum working loads. Internal trim components are precision-machined for optimal bean alignment and tight sealing. Full material test reports (MTRs) and API compliance certifications are available.
