Cast Steel Wafer Hard Seal Butterfly Valve：
Shop heavy-duty triple eccentric wafer butterfly valves with cast steel body and metal hard seal. PN16 rated for steam, oil, and high-temperature applications. Fast shipping to Southeast Asia and North America.
🔹 Product Introduction
Our Triple Eccentric Cast Steel Wafer Hard Seal Butterfly Valve is engineered for high-performance flow control in harsh industrial environments. Featuring a triple eccentric metal hard seal structure and WCB cast steel body, this PN16-rated valve delivers bubble-tight zero leakage, high temperature resistance, and exceptional durability. It is ideal for steam, hot water, oil, and weakly corrosive fluids, making it suitable for power plants, petrochemical facilities, and industrial systems across Southeast Asia and North America.
🔹 Core Features
01. Premium Cast Steel Construction
✅ High-Grade WCB Cast Steel Body: One-piece cast steel construction provides superior mechanical strength, impact resistance, and corrosion protection for high-pressure and high-temperature applications.
✅ Heat-Resistant Design: Built for high-temperature service, suitable for steam lines and thermal oil systems, maintaining structural integrity under thermal stress.
✅ Durable Coating: Anti-corrosion blue paint finish protects the valve body from rust and chemical exposure, ideal for humid tropical climates and outdoor industrial environments.
02. Triple Eccentric Hard Seal Technology
✅ Zero-Leakage Metal Hard Seal: The triple eccentric design eliminates friction between the disc and seat during operation, achieving bubble-tight shut-off with no internal leakage, even after thousands of cycles.
✅ Near-Zero Wear Sealing Surface: The offset disc structure prevents seal wear, extending service life and reducing maintenance costs in long-term industrial use.
✅ High-Temperature Resistant Seal Material: The metal hard seal is engineered to withstand high operating temperatures, outperforming soft-seal alternatives in steam and high-heat applications.
03. Versatile Industrial Performance
✅ Wide Media Compatibility: Suitable for steam, hot water, oil, natural gas, and weakly corrosive fluids, covering diverse industrial process requirements.
✅ Full Size Range: Available in DN50-DN300 (2"-12") sizes to meet the needs of small-scale facilities and large industrial projects alike.
✅ PN16 Pressure Rating: Rated for 1.6MPa working pressure, compatible with standard piping systems in both Southeast Asia and North America.
✅ Wafer-Style Installation: Compact wafer design for space-saving installation between standard flanges, ideal for tight-package industrial pipelines.
