TRIPLE OFFSET BUTTERFLY VALVE

Compared with double offset butterfly valves, the design of A triple offset butterfly valve is similar but with a metal seat and an additional 3rd offset (disc-seat contact axis), which makes it with better sealing and less wear, and it’s able to work under low/high temperature, higher pressure and various fluid.

What is a Triple Offset Butterfy Valves

A triple offset butterfly valve is an advanced valve designed for critical applications, offering exceptional performance and durability. This valve features three offsets: two from the centerline and one from the seating axis, creating a cam-like motion that eliminates friction during operation. This design ensures a tight seal and extends the valve’s lifespan, even in high-pressure and high-temperature environments. Ideal for industries such as oil and gas, petrochemical, and power generation, triple offset butterfly valves provide reliable, zero-leakage shut-off. Implementing these valves can enhance system efficiency, reduce maintenance costs, and ensure safe, long-term operation.
