1. Premium Materials, Quality Control from the Source
We strictly adopt 100% hot-rolled alloy round bars for forging, with core materials including:
- Duplex Steel F51 (2205): High yield strength (≥62 KSI), excellent corrosion resistance, stress corrosion cracking resistance, suitable for sour gas, seawater, and acidic/alkaline media;
- 316L/304 Stainless Steel: Compliant with ASTM A276/A479, high purity, superior rust and corrosion resistance, ideal for chemical, food & pharmaceutical, and water treatment applications;
- Nickel-Based Alloy Inconel 625: Designed for high-temperature and high-pressure, highly corrosive environments, yield strength ≥45 KSI;
- Carbon/Alloy Steel A105/4140: Preferred for high-pressure forgings, high mechanical strength, suitable for high-temperature steam and oil & gas transmission.
All raw materials are sourced from world-renowned steel mills with original material certificates. Each batch is tested by an ISO17025 (CNAS) accredited laboratory for full chemical composition, room-temperature tensile (Rp0.2/Rm), and hardness (HBW/HRC) to ensure material compliance and mechanical performance.
2. Precision Forging & CNC Machining, Meeting International Standards
Adopting a closed-loop forging process (electric arc furnace melting → hot-rolled round bar → precision forging → ball blank heat treatment → CNC finishing → mirror polishing → cleaning & packaging), with strict quality control at every stage:
- Forging Process: Hot-forged for dense grain structure, free of porosity, inclusions, and cracks, superior strength and toughness compared to cast balls;
- Dimensional Accuracy: Compliant with API 6D, ASME, DIN standards, tight tolerance ±0.01 mm, concentricity ≤0.02 mm, ensuring perfect seating with valve seats;
- Surface Finish: Mirror polishing (Ra ≤0.2 μm), scratch-free, burr-free, low operating torque, excellent sealing performance for zero leakage;
- Full Range of Sizes: Solid/hollow balls, floating/trunnion balls, 3-way balls (L/T port), V-port balls, extended stems (standard sizes including 1 13/16"), size range DN8～DN400 (1/4"～16"), pressure ratings 150LB～2500LB.
3. Rigorous Testing & International Certifications
Every valve ball undergoes 100% in-house inspection third-party random testing:
- Dimensional Inspection: CMM, micrometers, roughness testers;
- NDT: MT/PT/UT to detect surface and subsurface defects;
- Material Recheck: Spectroscopic analysis, tensile & hardness tests;
- Sealing Test: Hydrostatic/pneumatic test, helium mass spectrometry leak detection.
The factory is certified with ISO 9001, CE-PED, API 6D, ensuring test reports are internationally recognized.
