Features and MaterialsDesign and Applications

Features

  • Variable Restriction Control: Regulates flow and pressure using calibrated discs or interchangeable “beans.”
  • Extreme Durability: Trim in Stellite or tungsten carbide for maximum erosion resistance and long service life.
  • Flow Stability: Maintains stability under variable flow conditions and absorbs pressure shocks effectively.
  • High Precision: Provides exceptional control accuracy (<±1%), crucial for process regulation.
  • Automation Compatibility: Easily integrated into automated systems for remote operation.
  • Minimization of Adverse Phenomena: Optimized design minimizes cavitation and internal erosion.
  • Quick Maintenance: Interchangeable trim allows replacement without removing the valve body.
  • Reinforced Sealing: Ensures zero external leakage for improved safety and compliance.
  • Wide Control Range: Provides precise throttling from 0% to 100% open.
  • Regulatory Compliance: Meets API 6A and API 16C standards, ensuring suitability for oil & gas applications.

Body Design

  • Robust body capable of withstanding extreme pressure and abrasive conditions.
  • Available in monoblock or modular designs with flanged or threaded connections.
  • Optimized internal geometry minimizes turbulence and wear for precise control.
  • Complies with API 6A and API 16C standards, guaranteeing reliability.

Construction Materials

  • Body Materials: Carbon Steel (A105, A216 WCB), Stainless Steel (304, 316), Duplex/Super Duplex, Nickel Alloys (Inconel, Hastelloy), and special erosion-resistant materials.
  • Trim Materials (Internal): Internal components in hardened stainless steel or coated with Stellite/tungsten carbide, with seats and seals in high-temperature/pressure-resistant materials and special coatings for durability.

Trim Design

  • Adjustable or multi-position discs provide precise throttling control.
  • Manufactured from ultra wear-resistant materials (Stellite, tungsten carbide) for long service life.
  • Advanced sealing systems prevent leakage and maintain stable performance.
  • Interchangeable trim facilitates quick maintenance and adaptation to operating conditions.

Applications

  • Oil Production: Precise flow regulation in oil and gas wells.
  • Processing Units: Control of flow in crude separation and treatment processes.
  • Enhanced Recovery: Gas/water injection control for EOR processes.
