**Standards Compliance**
Our Tri-Eccentric Butterfly Valves are manufactured in accordance with international standards such as API 609, MSS SP-67, MSS SP-68, API 598, ASME B16.5, ASME B16.47, ASME B16.25, and ASME B16.34. These valves are designed for high-performance applications where tight sealing and durability are essential.
**Key Features**
The Triple Eccentric design ensures a bubble-tight shut-off in both directions. The unique geometry allows the disc to make contact with the seat only at the final closing position, eliminating friction and galling. This results in a resilient seal that provides excellent sealing performance even under high-pressure conditions.
**Applications**
These valves are widely used in industries such as metallurgy, power generation, petrochemicals, and water treatment systems. They are ideal for applications requiring reliable operation in high-temperature and high-pressure environments.
**Size & Pressure Range**
Available in sizes from 1/2 inch to 24 inches (DN15 to DN600) and pressure classes ranging from 150LB to 900LB (PN1.0 to PN6.4), these valves can be customized according to specific project requirements.
**Construction Materials**
The valve body and bonnet are available in carbon steel, alloy steel, stainless steel, and other materials upon request. Various end connections such as flanged, threaded, socket weld, and butt weld options are also available.
**Certifications**
We hold multiple certifications including ISO 9001, CE/PED, API 6D, SGS, and more. Our commitment to quality is reflected in our advanced manufacturing processes and rigorous testing procedures.
