API 609 Triple Eccentric Butterfly Valve – High-Temperature Solution

Key Structural Features
✅ Triple Eccentric Design:
API 609 Certified: Precision-engineered disc offset eliminates friction during operation, ensuring bubble-tight sealing (API 598 Class VI) even after 100,000+ cycles.
Metal-to-Metal Seats: Hard-faced 316L stainless steel seats withstand -29°C to +427°C extremes for steam, oil, and gas pipelines.

✅ Robust WCB Body:
ASTM A216 WCB Construction: Corrosion-resistant for refinery, petrochemical, and power plant applications.
Wafer Connection (API 609): Compact design reduces weight and installation costs vs. lug-type valves.

✅ Zero Maintenance & Longevity:
Triple-Layer Seal: Eccentric disc + tapered seat + graphite packing for triple leak protection.
Anti-Blowout Stem: ISO 5211-compliant stem design prevents ejection under high pressure (150LB~2500LB).

✅ High-Temperature Adaptability:
Extended Bonnet Option: Available for cryogenic (-196°C) or ultra-high-temperature (+593°C) services.

Industry Applications
Oil & Gas: Crude oil transfer lines, compressor station isolation.
Power Generation: Boiler steam control, turbine bypass systems.
Chemical Processing: Acid/caustic media regulation, high-temperature reactors.
Marine: Seawater cooling systems, fuel oil transfer.

Why Choose This Valve?
✨ Energy Efficiency: 30% lower torque vs. double eccentric designs.
✨ Global Compliance: CE, PED, and NACE MR0175 (sour service) certifications.
✨ Custom Solutions: Electropolished internals, gearbox/pneumatic actuation.
