OCT® Oblique Cone Technology Triple Offset Control ValveThe Severn Leeds OCT® may be the first triple offset butterfly valve designed from the outset to provide the ultimate in cutting edge butterfly control valve technology. Incorporating the 50 years’ experience in butterfly control of Severn Glocon Group and allied to real market feedback via the Groups’ “repair intelligence” capability, each facet of the valve has been designed to provide the most accurate, reliable and robust service capability possible:
Maximised bore valve with high CV and truly circular geometry
Low dynamic & sealing torque
Available with a range of low noise & anti-cavitation trims
Sealing rates for FCI 70.2 Class II to Class VI
Laminated & solid seal designs with a multitude of sealing materials to suit all applications
Actuated packages are supplied fully assembled and tested for peace of mind installation
Fully in-field serviceable
Severn Leeds OCT® Oblique Cone Technology 01
OCT® – The Art of ControlThe simplicity and ingenuity of OCT® represents the next generation of our pursuit of providing the ultimate in butterfly control valve technology.
02 Severn Leeds OCT® Oblique Cone Technology
Severn Leeds OCT® Technology
The patent pending OCT® design is based on an ‘infinite circle’ based geometry. By this method we avoid having to consider ellipses and can achieve a perfectly circular ‘patent pending’ triple offset geometry.
This simple yet elegant solution to TOV geometry allows a sealing area to be created using an ever decreasing set of perfect circles, giving full bore capability without the flat spot typically seen on most triple offset butterfly valves.
