Triple offset butterfly valves (TOVs), also called high-pressure butterfly valves, are perfect for offshore and upstream gas and oil industry applications. It is specifically used in the turret and topside applications of Floating Production Storage and Offloading vessels, gas compressions, separators and water treatment plants.
The triple offset valves were introduced in the 1970s in India as a significant improvement over the traditional butterfly valves, and it was a success since its inception. It evolved as a robust, effective and reliable alternative to gate and ball valves. TOVs come in different sizes, materials and rating, making them very useful for different applications. Triple offset valves are used in similar industries as the gate valves and double offset butterfly valves but for more demanding applications like super-heated steam, high-pressure steam, and high-temperature oil and gas. A study indicates that there are over half a million TOVs installed across the world.
