Overview
What Is a Triple Offset Butterfly Valve?
A triple offset butterfly valve is a metal seated quarter-turn valve designed with three offsets in its shaft and sealing geometry. This structure creates a non-rubbing sealing motion during operation and supports tight shut-off in severe service conditions.
Unlike resilient seated butterfly valves, triple offset designs are intended for high temperature, high pressure, and demanding process duty where metal-to-metal sealing reliability is required. They are commonly selected for critical isolation in systems where seat durability and shut-off integrity are essential.
Triple offset butterfly valves can be supplied in different body materials, sealing constructions, and actuation methods to match operating temperature, pressure class, media characteristics, and project specifications.
