Alis Valves is a trusted Triple Offset Metal Seated Butterfly Valve Manufacturer & Supplier in India, offering premium-performance butterfly valves for critical isolation, high-temperature, and high-pressure applications. Designed with advanced triple offset geometry and precision metal-to-metal seating, these valves eliminate seat friction during operation, ensuring bubble-tight shut-off, low operating torque, exceptional durability, and extended service life. They are ideal for oil & gas, petrochemical, power generation, refinery, steam, chemical processing, and industrial process systems.

Product Specifications and Overview

ALIS Valves offers Triple Offset Metal Seated Butterfly Valves for industrial applications requiring reliable flow isolation, tight shut-off and durability under demanding operating conditions. These valves feature a triple-offset disc and seat geometry designed to minimize friction between the sealing surfaces during opening and closing. The three-offset arrangement allows the disc to disengage from the seat as the valve opens, helping reduce wear, operating torque and sealing-surface damage over repeated cycles. The metal-to-metal seating design makes these valves suitable for applications where elevated temperatures, demanding process conditions or resistance to conventional soft-seat limitations are important considerations. Depending on the required specifications, the valve can be configured with suitable body and disc materials, metallic sealing components and manual, pneumatic or electric actuation for reliable operation.

Triple Offset Metal Seated Butterfly Valves are used in oil and gas facilities, refineries, petrochemical plants, power generation units, chemical processing systems and other industrial pipeline applications. Depending on the selected materials, pressure rating and temperature limits, they can be specified for compatible liquids, gases, steam and certain high-temperature process media. Important selection factors include valve size, pressure class, operating temperature, process media, body and disc materials, seat construction, allowable leakage rate and operating torque. The required flange connection, actuator type and control system compatibility should also be evaluated according to installation requirements. For critical isolation or fire-risk applications, buyers should verify the applicable pressure-temperature ratings, leakage requirements and relevant fire-safe testing or certification. Selecting the appropriate triple-offset configuration helps support dependable shut-off, reduced seat wear and consistent service performance under the intended operating conditions.

Frequently Ask Questions

It is a triple-eccentric butterfly valve with metal-to-metal seating, designed for high-temperature, high-pressure and severe-service applications.
Alis Valves manufactures and supplies Triple Offset Metal Seated Butterfly Valves for oil & gas, refineries, petrochemical, power generation, chemical, steam, hot oil, cement, steel, flue gas and other severe-service industrial applications.
The valve uses two eccentric shaft/disc offsets and a third offset in the conical sealing geometry. This produces a cam-like seating action and minimizes rubbing between the disc and seat.
A double-offset valve uses two eccentric offsets to reduce seat friction. A triple-offset valve adds a third offset to the sealing geometry, creating a non-rubbing, cam-like seating action.
