The Xidelong DN65 PN16 Wafer Dual Plates Check Valve is a high-performance non-return valve engineered for reliable backflow prevention in demanding industrial pipeline systems. Featuring a robust stainless steel CF8M (A351 Grade 316) body and dual spring-loaded discs, this wafer-type check valve delivers exceptional corrosion resistance, rapid closure, and maintenance-free operation across a wide range of applications.
| Feature | Benefit |
|---|---|
| Dual Plate Spring-Loaded Design | Torsion spring mechanism ensures instant, bubble-tight closure when flow reverses, preventing water hammer and system damage |
| CF8M Stainless Steel Body & Discs | Superior corrosion and oxidation resistance; suitable for aggressive media including seawater, chemicals, and high-temperature fluids up to 200°C |
| Compact Wafer Configuration | Ultra-short face-to-face dimension (per API 594) saves installation space and reduces pipeline weight; fits between standard flanges without additional supports |
| PTFE Soft Seat | Leak-tight sealing at low differential pressure; broad chemical compatibility; replaceable seat extends valve service life |
| Bi-Directional Sealing | Positive shutoff in both flow directions; fire-safe secondary metal-to-metal seat backup available on request |
Every Xidelong dual plate check valve undergoes the following quality control procedures before shipment:
