Product Description:

Product Overview:

Multi-layer hard seal flanged butterfly valves adopt innovative multi-layer hard seal technology, which can provide efficient sealing performance under various extreme working conditions. Such butterfly valves are usually made of temperature-resistant and corrosion-resistant materials such as stainless steel or alloy steel, and their sealing surfaces are usually coated with wear-resistant materials such as tungsten carbide or hard alloys to enhance durability.

Technical parameters:

  • Valve body material: WCB, CF8, CF8M, alloy steel, etc
  • Sealing material: stainless steel + graphite, metal-to-metal sealing, hard alloy overlaying, etc
  • Connection method: flange connection
  • Driving mode: manual, electric, pneumatic, hydraulic, etc
  • Pressure rating: PN10/16/25/40/64/100, etc
  • Operating temperature: -29℃ to +425℃ depending on material and design
  • Applicable medium: water, steam, oil, natural gas, acidic medium, etc
  • Valve size: DN50 to DN1200, larger sizes can be customized

Product Features:

  • Enhanced sealing performance: Multi-level sealing design ensures zero leakage under different pressures and temperatures.
  • High temperature and high pressure resistance: The selected materials and design enable the valve to work stably under high temperature and high pressure conditions.
  • Corrosion resistance: The materials of the valve body and sealing surface can be selected according to the characteristics of the medium to resist corrosion.
  • Wear resistance: The sealing surface is hard alloy surfaced, which increases the wear resistance of the valve.
  • Convenient maintenance: The structural design is reasonable, facilitating on-site maintenance and component replacement.

Application Scenario:

This type of butterfly valve is widely used in pipeline systems in the petroleum, chemical, metallurgical, power, and water conservancy industries to regulate or cut off the flow of media.
