This guide covers PTFE lined butterfly valve operation, components, and benefits of virgin PTFE with a 3‑4 mm thick liner (50% thicker than standard). The inert PTFE surface provides chemical resistance (pH 0‑14), purity, and bubble‑tight sealing from ‑40°C to 200°C. Applications include chemical, pharmaceutical, food, water, oil & gas, and semiconductor industries. It compares linings, offers a selection guide, and details quality tests (30KV spark, hydrostatic, traceability). From Tianjin Worlds Valve (19+ years), the article highlights virgin PTFE, thick liner, and certifications (ISO, CE, UKCA, etc.) ensuring reliable, low‑maintenance, cost‑effective control for aggressive and high‑purity fluids.
