  • Carbon Steels, Low Temperature Carbon Steel, Martensitic Steels, Austenitic Stainless Steel, Duplex Stainless Steels, Super Duplex Stainless Steels, Nickel Alloys, Nickel Aluminum Bronze, Hastelloy, Inconel, Titanium Alloy & Carbon Steel with Internal Corrosion Resistant Alloy (CRA) Overlay
  • Bolted Bonnet Design:
  • Feature: The bonnet is bolted to the valve body.
  • Benefit: Allows for easy access to internal components, facilitating maintenance and repair without removing the valve from the pipeline.
  • Globe Valve Design:
  • Feature: Globe valves have a spherical body shape with a movable plug (disc or disk) that regulates flow.
  • Benefit: Provides good throttling capability, allowing for precise control of flow rates.
  • Sealing Mechanism:
  • Feature: Uses a sealing mechanism (gasket or O-ring) between the bonnet and body.
  • Benefit: Ensures tight sealing to prevent leakage, maintaining process integrity and safety.
  • Materials of Construction:
  • Feature: Made from various materials such as stainless steel, carbon steel, or alloys.
  • Benefit: Can withstand a wide range of temperatures, pressures, and corrosive environments, ensuring longevity and reliability.
  • Pressure and Temperature Ratings:
  • Feature: Available in different pressure classes and temperature ratings.
  • Benefit: Suitable for diverse industrial applications, from low-pressure systems to high-pressure and high-temperature environments.
  • Versatile Applications:
  • Feature: Used in a variety of industries including oil and gas, power generation, chemical processing, water treatment, etc.
  • Benefit: Versatility in application, adapting to different fluid types and operating conditions.
  • Actuation Options:
  • Feature: Can be manually operated or actuated (electrically, pneumatically, or hydraulically).
  • Benefit: Allows for automation and integration into control systems for remote operation and monitoring.
