Common body materials include ductile iron (ASTM A536) for general industrial applications, offering excellent strength and castability, or stainless steel (SS304/SS316) for enhanced corrosion resistance, particularly in chemical or food processing environments. Discs can be made from ductile iron, stainless steel, or even aluminium bronze for specific media compatibility. Seats are typically EPDM, NBR, Viton, or PTFE, selected based on temperature, pressure, and chemical resistance requirements. The "red" designation often refers to the specific coating or body material, for instance, a vibrant epoxy coating over ductile iron for corrosion protection and visibility.
2. Casting/Forging: For ductile iron bodies, casting is the primary method, ensuring complex geometries are achieved efficiently. Stainless steel components may undergo casting or forging, depending on the required mechanical properties and scale. Precision molds and controlled cooling rates are crucial to prevent material defects.
3. CNC Machining: Post-casting/forging, components undergo high-precision Computer Numerical Control (CNC) machining. This step ensures exact dimensions for the bore, flange connections, shaft holes, and seat retention areas, critical for tight sealing and smooth operation. Tolerances are typically held within microns to ensure interchangeability and consistent performance.
4. Surface Treatment & Coating: For valves like the red butterfly valve, the body often receives a specialized coating, such as fusion-bonded epoxy. This coating provides superior corrosion resistance, extends service life, and gives the valve its characteristic color. Proper surface preparation (e.g., sandblasting) is essential for coating adhesion.
5. Assembly: Skilled technicians meticulously assemble the valve, integrating the body, disc, shaft, seat, and packing. Precise torque settings are applied to ensure proper sealing without over-stressing components.
6. Testing & Quality Assurance: Every valve undergoes rigorous testing, including hydrostatic shell tests (to confirm pressure containment capability) and seat leakage tests (to verify bubble-tight shut-off), adhering to standards like API 598, ISO 5208, and ANSI B16.104 Class VI. Visual inspection, material verification, and dimensional checks are also performed.
7. Final Inspection & Packaging: Valves are inspected for cosmetic flaws, proper labeling, and then carefully packaged to prevent damage during transit.

This comprehensive process ensures that each valve meets stringent performance criteria, offering exceptional reliability and a long service life of typically 15-20 years under normal operating conditions. Target industries include petrochemical, metallurgy, water supply & drainage, HVAC, and food & beverage, where energy saving and corrosion resistance are paramount advantages.
