Material Construction & Components
Built to withstand aggressive media, thermal cycling, and high line stresses, the Audco 3-piece ball valve utilizes premium-grade cast and forged metallurgies.
- Body & End Connectors: Carbon Steel (ASTM A216 WCB / ASTM A105), Stainless Steel 304 (ASTM A351 CF8), and Stainless Steel 316 (ASTM A351 CF8M).
- Ball & Stem Assembly: High-grade AISI 316 / ASTM A479 TP316 mirror-finished solid floating ball with an anti-blowout stem design.
- Seat Ring Options: Virgin PTFE, Carbon-Filled PTFE (CFT), Glass-Filled PTFE (GFT), and PEEK (for elevated temperature and pressure service).
- Gland Packing & Seals: Flexible graphite stem packing with secondary metal-to-metal seating for fire-safe integrity.
Key Engineering Advantages
- Inline Serviceability (Swing-Out Design): The center body section can swing out by removing body bolts, allowing maintenance technicians to inspect or replace seats and seals without removing the end connectors from the pipeline.
- Anti-Blowout Stem Architecture: Features a bottom-entry stem loaded with an integral collar that prevents stem ejection, even during abnormal line pressure surges.
- Fire-Safe & Anti-Static Protection: Built-in antistatic grounding devices ensure electrical continuity between ball, stem, and body, while secondary metal seats ensure shut-off if soft seats burn out during a fire.
- Actuation-Ready Platform: Equipped with an ISO 5211 mounting pad to streamline direct mounting of pneumatic actuators, electric actuators, or limit switch boxes.
Primary Industrial Applications
Audco 3-piece ball valves are the preferred choice for applications requiring frequent cycling and minimal downtime:
- Steam & Condensate Service: Boiler feed lines, steam distribution headers, and condensate drainage.
- Chemical & Petrochemical Processing: Aggressive acid transfer, solvent lines, and hydrocarbon piping.
- Industrial Utilities: Compressed air supply, cooling water circuits, and nitrogen inerting lines.
- Pharma & Fine Chemicals: High-purity fluid transfer, CIP/SIP lines, and process vessel isolation.
