Manufacturing Process of Groove Butterfly Valve (Process Flow Visualization)

1. Material Selection ⟶ Use certified ductile iron (EN-GJS-500-7) & corrosion-resistant alloys

2. Casting & Raw Forging ⟶ Precision metal casting for body & disc (ISO/ASTM standard casting foundry)

3. CNC Machining ⟶ High-accuracy CNC turning & drilling to ensure groove tolerances (±0.02mm)

4. Surface Treatment ⟶ Epoxy powder coating, nickel-plating, or PTFE lining for corrosion resistance

⟶ 5. Assembly & Seat Insertion ⟶ Robotic installation of EPDM/NBR seat & anti-leak disc

6. Final Inspection & Testing ⟶ Hydrostatic pressure testing as per ISO 5208/ANSI; cycle life >10,000

⟶ 7. Packaging & Marking Every valve traceable via batch QR code & documentation

Professional FAQ on Groove Butterfly Valves

1. What are the primary materials used in groove butterfly valve bodies and discs?

Body materials are typically high-grade ductile iron (EN-GJS-500-7/ASTM A536), valued for strength and ductility. Discs use nickel-plated ductile iron or stainless steel for added corrosion resistance in aggressive fluids.

2. What seat materials are most common, and how are they selected?

EPDM and NBR elastomer seats are standard, chosen based on compatibility (EPDM for water, NBR for oil/air, PTFE for chemicals). All seat materials on certified valves conform to WRAS/NSF58 for potable water systems.

3. What are the typical actuator and operation mechanisms available?

Most grooved butterfly valves are available in lever-operated, worm gear, electric actuator, or pneumatic actuator versions. Electric and pneumatic are favored for building automation and remote API integration.

4. Which installation standards should be followed?

Valves conform with ISO 6182-12 (grooved connections), AWWA C606, and NFPA 13 (for fire protection). Always check for UL/FM listing where required.

5. What are the major advantages over flanged or welded butterfly valve designs?

Grooved end butterfly valves reduce installation time by up to 70%, minimize potential leak paths, and simplify future maintenance, making them ideal for modular construction and MEP projects.

6. What is a typical delivery lead time and warranty period?

Standard sizes (2"–12") from top brands are usually available within 10–20 work days. Warranty periods are generally 12–24 months against manufacturing defects; extended terms on project basis.

7. How are groove butterfly valves pressure-tested and certified?
