Published: 30th April 2025 | Issue 98 Share article:

In the dynamic landscape of industrial engineering, innovation often stems from a rich heritage of expertise and an unyielding commitment to excellence. Severn, a renowned name in the world of valve design and manufacturing, have once again proven this statement true with the Oblique Cone Technology (OCT) Triple Offset (TOV) Butterfly Valve.

Severn’s journey to engineering eminence is built upon innovation and dedication stemming back over 60 years. Severn has continuously pushed the boundaries of valve technology, and at the heart of Severn’s latest engineering triumph lies the OCT TOV Butterfly valve, a revolutionary advancement in Butterfly valve design and performance.

The OCT TOV Butterfly Valve introduces circular sealing geometry; unlike most traditional triple offset designs that use an ellipse. The benefit of circular geometry is that it provides a uniform sealing load around the circumference of the sealing diameter, providing a reliable and repeatable shut-off, it allows Severn to use proven circular sealing knowledge and incorporate this into the TOV.

Incorporating Severn’s ‘Repair Intelligence’ knowledge which involves providing real market feedback from extensive in-depth analysis from failed valves. Severn have designed each facet of this valve to provide the most accurate, reliable, and robust service capability possible whether managing critical processes in Oil & Gas, refineries, Chemical Plants, or Power Generation facilities.

The introduction of the innovative OCT TOV Butterfly Valve signifies a paradigm shift in valve technology, offering a host of benefits:

Extended Lifecycle: Process conditions can change with time. Severn have ensured the interchangeability of the seal, should the process conditions change, so can the seals.

Increased Safety: Safety is paramount to the design of our products and whilst adhering to the strictest industry standards, Severn have incorporated dual shaft blowout prevention as standard to the OCT valve.

Versatility: The OCT Butterfly valve has been designed for both superior control in both throttling and modulating services, whilst providing a repeatable seal for isolation duties. 

Environmental Sustainability: Reducing fugitive emissions for end users to meet tightening specifications, the OCT butterfly valve range offers the fugitive emissions packings as standard.

Severn’s relentless pursuit of engineering excellence has culminated in the development of the OCT Triple Offset Butterfly Valve – a testament to the company’s unwavering commitment to innovation and customer satisfaction. Severn stands ready to lead the way, setting new benchmarks for performance, reliability, and efficiency in valve technology.
