Three-Piece Ball Valve: Modular Design for Versatile Control
Product Introduction
The three-piece ball valve excels in demanding fluid control with its modular tri-segment architecture. The precision-cast body features a hydraulically optimized flow path, reducing pressure loss by 12% for high-velocity media. PTFE seats dynamically compensate for ball wear via elastic preload, ensuring lasting sealing performance. The removable central body permits critical part replacement during operation, minimizing downtime. With galvanized or stainless steel stems, it adapts to food processing, biopharma, and general industrial environments. Manufactured under ISO9001 standards, this valve sets new benchmarks for efficiency and adaptability.
Product Features
The three-piece ball valve features a tri-segment modular design: two CF8/CF8M stainless steel or carbon steel end flanges bolted to a central body, suitable for PN16 pressure and media ≤120°C. The precision-lapped ball (roundness ≤0.02mm) pairs with a PTFE seat or metal hard seal for bidirectional zero leakage in high-purity liquids, gases, and mildly corrosive fluids. Stem options include galvanized steel, 2Cr13 stainless steel, or 304 stainless steel, coated for enhanced durability. The detachable central body enables in-line seal replacement without pipeline shutdown.
Product Advantages
In-Service Maintenance
Central body detachment allows rapid component replacement, boosting efficiency by 50% over conventional valves.
01
Sealing Flexibility
PTFE seats resist weak acids/alkalis; metal seats handle high-temperature or abrasive media.
02
Hygienic Performance
Smooth full-bore flow path minimizes residue buildup for pharmaceutical and food-grade applications.
03
Long-Term Reliability
Anti-ejection stem design and dual packing ensure stability under frequent cycling.
04
Universal Compatibility
ISO 5211 flanges support ANSI, DIN, and other standards, covering DN15-DN300 pipelines.
