Product Detail

Butterfly Valve Components & Material – JIS F7480 Flange Butterfly Valve

The JIS F7480 flange butterfly valve stands as a pinnacle of high performance butterfly valves. Designed to excel in demanding marine environments, each component of this flange valve is meticulously crafted using specific materials. This thoughtful selection ensures optimal performance and durability, allowing the valve to withstand the rigors of harsh marine conditions.

  • Body: The body of the flange valve can be made of cast iron, ductile iron, or cast steel, providing strength, durability, and resistance to pressure and environmental conditions.
  • Disc: The disc, responsible for controlling the flow of the fluid, can be made of various materials depending on specific requirements. Options include Ductile Iron (DI) or WCB (cast carbon steel) with galvanization, stainless steel, or bronze. The choice of material depends on factors such as the type of fluid, temperature, and required corrosion resistance.
  • Stem: The stem connects the handle or actuator to the disc, enabling the flange valve’s opening and closing. Stainless Steel is commonly used for the stem due to its corrosion resistance and mechanical strength.
  • Seat: The seat is the sealing surface between the disc and the valve body. Various materials can be used for the seat, including NBR, EPDM, CR, FKM, VITON, or PTFE. The selection depends on factors such as the fluid type, temperature range, and compatibility with the disc material.
  • Gear: If the flange butterfly valve includes a gear mechanism for manual operation, the gear is typically made of Ductile Iron. This material provides strength and durability to handle the forces involved in operating the valve.
  • O-ring: The O-ring is a sealing element used to prevent leakage between the moving parts of the valve. In the case of the JIS F7480 flange butterfly valve, the O-ring is made of NBR, which offers good resistance to oil, fuel, and other non-polar fluids.
  • Pin: The pin connects the disc to the stem, allowing for rotational movement. Stainless Steel is commonly used for the pin due to its strength and corrosion resistance.
