Product Description
DN50 PN16 Flanged Ball Valve CF8M — Degreased & Oxygen Clean Full Bore Floating Ball for Oil Free Service
The Xidelong DN50 PN16 Flanged Ball Valve is a premium full-bore floating ball valve specifically processed with degreasing and oxygen-cleaning treatment for oil-free service applications. Manufactured with a CF8M (ASTM A351 Grade 316) stainless steel body, ball, and stem, this valve is engineered to meet the stringent cleanliness requirements of oxygen pipelines, high-purity gas systems, and critical process industries where hydrocarbon contamination is unacceptable.
Degreasing & Oxygen Clean Process
Each valve undergoes a rigorous multi-stage cleaning protocol:
- Alkaline Degreasing Bath: Complete immersion in heated alkaline solution to remove all machining oils, cutting fluids, and surface grease
- Ultrasonic Cleaning: High-frequency ultrasonic cavitation in deionized water to dislodge micro-particulate contaminants from threaded connections and cavity surfaces
- Final Rinse: Multiple deionized water rinses to eliminate residual cleaning agents
- Hot Air Drying: Filtered hot air drying in a cleanroom environment to prevent recontamination
Key Features
| Feature | Benefit |
|---|---|
| CF8M Stainless Steel Construction | Superior corrosion resistance across body, ball, and stem; compatible with high-purity media without metallic ion leaching |
| Full Bore Design | Unrestricted flow path with zero pressure drop; identical to pipe inner diameter for pigging and maximum flow efficiency |
| Blowout-Proof Stem | Bottom-entry stem with integral shoulder prevents stem ejection under pressure; anti-static device between stem and ball ensures electrical continuity |
| ISO 5211 Mounting Pad | Standardized top flange for direct mounting of pneumatic or electric actuators without custom bracket fabrication |
