triple offset butterfly valve have three separate offsets compared to the two in a double-offset valve. These offsets create a cone type shape for both the disc and the seating surface on the valve seat which makes this valve much more durable, robust, and hard-wearing than its double-offset counterpart. This also allows the valve to be used in applications with a high temperature that may deteriorate or damage a soft seat. These valves are typically used in more demanding applications where a tight bubble shut off is required or a tough sealing surface is needed that will provide zero leakage(soft seat) or rated leakage(metal seat).
The Anatomy of a Triple Offset Butterfly Valve: Exploring Its Key Components
This type of valve is ideal for applications with highly corrosive and abrasive materials, steam or high-temperature liquids, and can be found in many industries such as oil and gas processing, power generation and pulp and paper. Triple-eccentric butterfly valves are more expensive than other types of butterfly valves, but they offer a higher level of performance in critical service applications that require a high degree of precision with minimal maintenance requirements.
