中文Hard Seal Ball Valve Balls: 100,000+ Cycles Zero Leakage for Oil & Gas
Date:5/14/2026 2:42:04 AM Click:2
In high-temperature, high-pressure and abrasive working conditions (e.g., oil & gas, petrochemical, coal chemical), ball valve balls are the core component determining sealing performance and service life. Our hard seal ball balls adopt integrated forging tungsten carbide (WC) spray coating, achieving API 6D fire-safe and ISO 15848-1 fugitive emission Class B certification.
Key advantages：
- Wear resistance: 3–5× longer life than standard stainless steel balls
- Sealing: Bidirectional VI 级 leakage tightness, zero leakage after 100,000 cycles
- Material: AISI 316, 440C, F6a, Inconel 625 for corrosive/H₂S service
