Butterfly Triple Eccentric / Offset Valves (TOBV) – High Performance & Fire-Safe Design Triple Eccentric Butterfly Valves (TOBV) are advanced metal-to-metal seated valves engineered for both precise throttling and reliable positive isolation. Their unique triple offset design eliminates friction between the disc and seat during operation, ensuring smooth movement, minimal wear, and long service life. These valves are increasingly replacing conventional gate and ball valves due to their superior efficiency and compact construction. The Advance BT series features a replaceable seat and seal configuration, which significantly reduces maintenance time and eliminates the need for spare valves. Designed for bi-directional flow, these valves provide tight, leak-proof shut-off and consistent performance even in high-pressure and high-temperature environments. With quarter-turn operation, TOBV ensures quick response, easy handling, and low maintenance. Their robust metal-seated construction makes them intrinsically fire-safe and suitable for critical applications, including cryogenic and high-temperature services. Key Features: Size range: 3” to 100” Pressure ratings: ANSI Class 300, 600 & 900 Temperature range: -196°C (Cryogenic) to 900°C (Fire-safe applications) Metal-to-metal seating for high durability and fire safety Bi-directional flow capability with zero-leakage performance End connections: Wafer, Lugged, Flanged, Butt Weld Special designs: Jacketed, Zero Leakage, Custom configurations Compliance with API 609, API 598, API 607, BS 6364 standards Compact design with low fugitive emissions (FE) Suitable for large capacity and critical industrial applications FAQs 1. Who manufactures triple offset butterfly valves in India? Several reputed manufacturers produce TOBV in India, with Advance Valves being known for high-quality, engineered solutions for industrial and HVAC applications. 2. What is the difference between unidirectional and bidirectional valves? Unidirectional valves allow flow in only one direction, whereas bidirectional valves can handle flow in both directions while maintaining proper sealing. 3. What is a soft seated butterfly valve? A soft seated butterfly valve uses elastomeric materials like EPDM or PTFE for sealing, suitable for lower temperature and pressure applications. 4. What is the difference between a soft seat and a metal seat butterfly valve? Soft seat valves provide tighter sealing at lower pressures but are limited in temperature range. Metal seat valves, like TOBV, can handle extreme temperatures and pressures, making them ideal for critical and harsh environments. Triple Eccentric Butterfly Valves offer a reliable, efficient, and future-ready solution for industries requiring high performance, safety, and durability.
