Process Flow Overview:

• 1. Material Selection & Procurement: This foundational step involves selecting high-grade materials based on application requirements. For `cast iron wafer butterfly valve` bodies, ductile iron (e.g., ASTM A536) or gray cast iron (e.g., ASTM A126) are common, while stainless steels (e.g., SS304, SS316) are chosen for corrosive environments. Discs often utilize ductile iron, stainless steel, or aluminum bronze, and seats typically involve EPDM, NBR, Viton, or PTFE for varying chemical resistance and temperature ranges. All materials are sourced from certified suppliers to ensure traceability and material integrity.
• 2. Body Casting or Forging:
  • Casting: For larger valves or complex geometries, molten metal is poured into meticulously designed molds. This process, often employing sand casting for iron valves, ensures the body's structural integrity and dimensional accuracy.
  • Forging: For higher pressure ratings or enhanced strength, especially in stainless steel valves, forging involves shaping solid metal through hammering or pressing. This refines the grain structure, enhancing mechanical properties.

  Post-casting/forging, rough machining, heat treatment (stress relieving), and shot blasting are performed to prepare the body for subsequent stages and enhance its durability.

• 3. CNC Machining: Precision Computer Numerical Control (CNC) machining transforms the raw body and disc components into their final dimensions. This stage is critical for achieving tight tolerances for the shaft bore, disc edge, and seat pocket, ensuring smooth operation and leak-tight sealing. Modern CNC machines provide repeatability and accuracy essential for high-performance valves.
• 4. Surface Treatment: Depending on the material and application, valve components undergo various surface treatments. For cast iron bodies, epoxy coating or galvanizing provides corrosion resistance. Stainless steel parts might undergo passivation. These treatments enhance the valve's resistance to environmental factors and media corrosion.
• 5. Assembly: Skilled technicians meticulously assemble the valve components: disc, stem, seat, bushings, and packing. Precise alignment and torque control are crucial during this stage to ensure proper functionality and sealing.
• 6. Testing & Quality Assurance: Every butterfly wafer type valve undergoes a series of stringent tests to verify its performance and integrity.
  • Hydrostatic Shell Test: Checks the pressure-retaining capability of the valve body (e.g., 1.5 times the rated pressure as per API 598).
  • Low-Pressure Air Seat Test: Verifies the bubble-tight seal of the valve seat against low-pressure air (e.g., 80 PSI for Class VI shutoff).
  • High-Pressure Seat Test: Checks seat integrity at higher pressures using water or inert gas.
  • Functional Testing: Ensures smooth operation of the disc and stem, proper opening/closing, and torque requirements.
  • Non-Destructive Testing (NDT): For critical applications, methods like radiography, ultrasonic testing, or magnetic particle inspection may be used to detect internal flaws.
• 7. Packaging & Shipping: Valves are thoroughly cleaned, protected against corrosion, and securely packaged to prevent damage during transit. Documentation, including material certificates and test reports, accompanies each shipment.

This rigorous process ensures a typical service life of 10-20 years for a well-maintained wafer style butterfly valve, depending on the application and media. Target industries benefiting from these advantages include petrochemical for its corrosion resistance, metallurgy for high-temperature resilience, and municipal water supply & drainage systems for energy-saving flow control and leak prevention.
