Metal to Metal Butterfly Valve Features

Metal to Metal Butterfly Valve features robust metal-to-metal sealing, ensuring tight shutoff even under high temperatures and pressures.

 

With versatile end connections (flanged, lug, wafer), it integrates easily into pipelines. Fire-safe by design, it maintains performance during extreme conditions. Suitable for handling abrasive or corrosive media, it delivers reliable flow control in critical applications where resilience and long-term sealing integrity are paramount.

Metal to Metal Butterfly Valve Advantages & Application

Metal to Metal Butterfly Valve Product Advantages

  • Durable Sealing: Metal-to-metal design resists high temperatures, corrosion, and abrasion, maintaining tightness even after 10,000+ cycles—critical for hazardous or high-value media.
  • Low Wear Operation: Triple offset design eliminates friction, extending service life by 50% compared to standard butterfly valves in frequent-operation systems.
  • High-Temp Adaptability: Withstands up to 600℃, suitable for superheated steam and high-temperature industrial fluids where soft-sealed valves fail.
  • Energy Efficiency: Streamlined flow path minimizes pressure drop, reducing pump energy consumption by 8~10% in high-flow systems.
  • Broad Compatibility: Handles diverse media (steam, oil, gases) and adapts to corrosive environments with material upgrades (e.g., 316 stainless steel).

Metal to Metal Butterfly Valve Application Fields

  • Power Generation: Controls superheated steam in boiler systems, turbine bypass lines, and heat exchangers, ensuring stable operation in thermal power plants.
  • Petrochemical Industry: Regulates hot hydrocarbons, molten sulfur, and process fluids in refineries and chemical plants, withstanding corrosive and high-temperature conditions.
  • Metallurgy: Manages high-temperature gases and cooling water in steel mills and smelting furnaces, enduring thermal cycling and abrasive media.
  • Industrial Heating: Controls hot oil and thermal fluids in district heating networks, ensuring efficient energy transfer without leakage.
