Features & Benefits

Resilient Metal Sealing Technology

Integral metal hard seal valve seat for durability and superior sealing performance.

Engineered for triple-offset (three-eccentric) sealing structures as well as advanced four-eccentric, and five-eccentric sealing structures, ensuring optimized performance in various applications.

Outstanding Sealing Performance

Bidirectional pressure sealing with zero leakage, verified through rigorous testing.

Handles high pressures up to 2500 LB, meeting the most demanding industrial standards.

Wide Temperature Compatibility

High-temperature performance up to +850°C for heat-intensive processes.

Reliable operation at cryogenic temperatures as low as -196°C, ideal for LNG and extreme cold conditions.

Exceptional Resistance

Superior wear resistance, erosion resistance, and corrosion resistance for extended service life, even in harsh environments.

Effortless Operation

Zero friction and ultra-low torque make opening and closing smooth and efficient.

Designed for easy replacement and maintenance of sealing rings and valve body seats.

Inherent Safety Features

Fire-safe design for increased safety in hazardous applications.

Versatile Media Compatibility

Suitable for a wide range of media, including water, steam, oil, gas, acids, alkalis, and salts, offering flexibility for diverse applications.
