True Zero-Leakage Metal-to-Metal Sealing
The triple-offset geometry creates a torque-seated, metal-to-metal seal that achieves bi-directional bubble-tight shutoff without relying on seat deformation.
Triple Offset Disc Geometry
Three independent offsets eliminate friction between the disc and seat during opening and closing, preventing galling and extending sealing life.
Non-Rubbing Sealing Action
Unlike concentric or double offset butterfly valves, the disc disengages from the seat immediately upon opening, minimizing wear and reducing operating torque.
Excellent High-Temperature Performance
Metal-seated construction withstands temperatures up to 650°C (1202°F), making it ideal for steam, thermal oil, and other high-temperature services.
Suitable for High-Pressure Applications
Designed to operate reliably under pressure ratings up to ASME Class 2500, ensuring dependable performance in severe operating conditions.
