Hard Seal Ball Valve

The Hard Seal Ball Valve is a high-performance valve designed for demanding applications in various industries, including oil and gas, chemical processing, power generation, and water treatment. Its robust construction and advanced sealing technology ensure reliable operation, even under extreme conditions such as high pressure, high temperature, and corrosive environments.
  • Durable Construction: Made from high-quality materials such as stainless steel, carbon steel, or alloy steel for enhanced durability.
  • Hard Sealing Technology: Utilizes metal-to-metal sealing for superior leak-proof performance in high-pressure and high-temperature applications.
  • Low Maintenance: Designed for long service life with minimal maintenance requirements.
  • Versatile Applications: Suitable for a wide range of media, including gases, liquids, and slurries.
  • Fire-Safe Design: Compliant with API 607/API 6FA fire-safe standards.
  • Bi-Directional Sealing: Ensures tight sealing in both flow directions.
  • Oil and gas pipelines
  • Chemical and petrochemical plants
  • Power generation facilities
  • Water and wastewater treatment
  • Mining and slurry handling
