How Triple Offset Butterfly Valves Work

Our Hand Lever or Worm Gear operated Triple Offset Butterfly Valve (Wafer Type) is fire-safe designed with a metal-to-metal seated valve, suitable for throttling and positive isolation applications. It supports bi-directional flow control, zero leakage, and low fugitive emissions. The triple offset design eliminates disc-to-seat rubbing, as the disc energizes the seat upon closure, ensuring a tight, high-performance fit.
