Severn’s patented OCT technology takes the traditional TOV sealing technology even further to maximise the sealing benefits. The Oblique Cone Technology (OCT) moves away from the traditional elliptical shape and provides circular sealing geometry, thus allowing the proven double offset sealing knowledge to be applied and incorporated into the TOV.

In addition to this, trims that are traditionally found on double offset valves such as the Anti-Cavitation trim, can be used in our TOV design, making the TOV OCT the ultimate valve for both isolation and control applications.

Severn’s considerable investment in research and development for the TOV OCT has been key to introducing hybrid sealing technology to the TOV. By utilising our hybrid polymer metallic seal, we can apply the self-compensating benefits of the TOV to a polymer seal. Coupling this with the metallic element of the seal, means that should the soft seal become damaged in operation, the metal seal would take over and still provide an entirely reliable seal.

The hybrid seal has also undergone an extensive and strict regime of testing, including cycle testing & fire testing, thus proving that even in extreme conditions the TOV can still provide a suitable seal. This would not be the case for a double offset valve as if damage was to occur, the seal would need replacing resulting in unplanned down time and loss in production.

The TOV OCT is self-compensating for wear, meaning consistent sealing performance, time after time. The Camming action of the 3rd offset reduces seal wear by minimising seal contact. The disc and seal only contact each other in the last 1-2° of operation, not only minimising wear but also reducing friction. Comparing this to a double offset valve which contacts for around 10°.

The standard design of the TOV incorporates the requirements of the most stringent specifications, Dual anti-blowout design comes as standard, ensuring the shaft cannot be ejected from the valve. The hybrid polymer seal is fully compliant with EN ISO 90079-36 (ATEX) requirements.

Despite the fault proof capabilities of the hybrid seal, we know site conditions can change and become more arduous or change from the initial operating conditions given for the valve. To combat this, we have ensured the seals are interchangeable, the hybrid seal can be changed to a laminated seal, or if conditions dictate, a solid seal. This can be done without the need for main valve components being replaced ensuring the TOV OCT is fully in-field serviceable, and the valve can be upgraded on site, enabling you to achieve your core imperatives of safe operations and reduced downtime.

Severn were recently approached by a UK Petrochemical client to create a solution to assist in the reduction of noise and harmful emission pollution at their facility. The client was moving from a standard flare system to a new enclosed ground flare (EGF) system in an effort to improve reliability and reduce noise and combustion related emissions.

An enclosed ground flare system is designed to include advantages over an elevated flare system such as:

Severn’s 48’’ Butterfly valves were designed as the main Control valve for the new ground flare system, therefore had to be designed to reflect the safety critical nature of the application and the stringent specifications & testing regime set by the client. The valves and accessories were supplied SIL certified to integrate into the clients SIL rated system.

The 48’’ Butterfly valves were double flanged, designed to fit between the clients ASME 150 flanges. The valves also had a replaceable RPTFE seal to give repeatable Class VI shutoff. The bodies of the Butterfly valves were manufactured in ASTM A352 LCB (Carbon Steel) and the discs in ASTM A351 CF8M (Stainless Steel) to ensure the valve performed as designed when operating at temperatures from -45C to +50C. The valves were operated by a Quifer Scotch Yoke Actuator with smart positioner and instrumentation.

Severn was approached by a leading international oil company to replace the main water injection valve on their FPSO due to the existing valve passing and so not able to generate the required pressure. This problem was estimated to be costing the company a significant loss in oil production, so a quick response and solution was vital.

Severn were asked to provide a complete replacement trim to enable the oil company to refurbish the original valve while they waited for the replacement valve. The standard lead time for a full set of trim parts is 22 weeks and for a complete valve replacement is around 30 weeks, but due to the urgency, Severn manufactured and delivered a new set of trims in 12 weeks and the new valve in 20 weeks. This phenomenal effort was achieved by careful management of the sub suppliers and the remarkable effort by all involved at Severn.

A spokesperson for the oil company said, ”We would like to sincerely thank the whole Severn team for the hard work they have all put in to manufacturing the valve and delivering it on time.” This remarkable effort has also provided an opportunity to refurb the original valve and suggest an upgrade to the recently installed valve to avoid this situation occurring again.

Severn were approached at a external technology event, to assist in engineering a solution for a Onshore Oil & Gas client based in the MEA region that was having severe issues with multi-stage trim Flow Control valves failing after only a matter of weeks installation.

The images to the right are of one of the competitors multi-stage trim Flow Control valves that had failed after a few weeks of installation. As you can see the level of erosion and cavitation is extremely severe and highlighted how demanding the application was due to dealing with fluids such as formation water, produced water, saline, sand, and dissolved gas flowing through the valve.

Identifying the Challenges

After extensive conversations with the client, it was agreed that Severn would provide a high-performance Flow Control valve for this bespoke application issue. One of the initial challenges set by the client was the challenging acceptance criteria for what would pass as success or failure for the valves performance.
