Metal Seated Triple Offset Butterfly Valve – TEJI, Class 150–600LB, ≤425°C, Zero Leakage

The Metal Seated Triple Offset Butterfly Valve by TEJI is engineered for high-precision flow control and secure shut-off in demanding industrial environments. Designed with a triple offset mechanism, this valve ensures zero-leakage performance, even under high temperature and pressure conditions. The offset configuration eliminates friction between the disc and seat during operation, enhancing durability and sealing integrity.

Capable of operating at temperatures up to 425°C, this butterfly valve is ideal for critical service in metallurgy, electric power, petrochemical, water treatment, municipal, and drainage systems. Its metal seat construction guarantees long service life in corrosive and high-temperature applications.

Available in multiple end connection types—flanged, wafer, lug, or butt welded—the valve conforms to API 609, ASME B16.10, and ISO 5752 standards, ensuring dimensional compatibility and reliability. Safety features such as a fire-safe design and anti-blowout shaft provide added protection in hazardous operating conditions.

With flexible actuation options including manual, electric, pneumatic, or hydraulic, the TEJI triple offset butterfly valve supports advanced automation and integration into industrial flow control systems.
