Severn Glocon Ltd is recognised on a worldwide basis as one of the leading severe service control valve specialist manufacturing companies. Industry specialist areas include Oil & Gas, LNG/NGL, Industrial Gas and Power. The company has major project references in all areas of the world.

Headquartered in Gloucester, UK the Group has manufacturing centres in the U.K, Central Europe and India, but remains close to its global customer base with application engineers and service support local to all of the key markets.

Severn Unival Ltd is considered by many major operating companies as a leading specialist in the areas of Valve Management and Aftermarket Plant level support. Areas of expertise include specialist valve repair/service activities, the provision of valve failure analysis studies/performance improvement solutions, custom valve design/manufacture and stock inventory management. The company operates numerous major Oil & Gas Valve Management contracts throughout the world.

Severn Project Services provides technology-led design and project aid to major clients worldwide.

Controlling costs and keeping projects on programme are major challenges for all project managers. By working at the design end of the project, we aim to reduce the potential for errors and defects, which impact on fabrication and construction. Our service is designed to join the project lifecycle at any point, with experience in all major process markets.

Specialists in critical & severe service control & choke valves

Expertise in control and choke valve performance

Experience – a new level of performance

Enhanced performance through repair analysis

Valve development and optimisation is centred on our unique ‘Repair IntelligenceTM’ process; a continually evolving aftermarket-derived knowledge base incorporating failure analysis, repair solutions, performance data, and engineering capability for all makes of valves. This unrivalled scope of expertise ensures the development of a core product range that has been refined and proven in the field, offering optimum operational life on the most severe applications.

The Severn Glocon Series 5500 control choke valve is the result of field-proven valve solutions and an integrated approach to the life cycle considerations of the plant operators. The pioneering use of severe service material selection alongside a range of single and multi-stage trims means that even in the most exacting of flow control applications the operator will experience a significant increase in performance and a reduction in maintenance and operational costs.

Essential elements for success

The final decision on the selection of the valve/trim design combination best suited to a specific duty must be based on factual process data and extensive knowledge related to the requirements of the application. Severn’s Technical Sales group have extensive knowledge related to choke valve applications and the potential for valve failure situations. The understanding of the operating requirements for the valve is the primary factor in the valve selection process.

Trim design to application guide

Concentric Cage (CC) Range

Single and multiple heavy section ‘drilled hole’ cage (1CC to 3CC) design options. Developed to provide ‘low pressure recovery’ within the flow stream to reduce the potential for excessive noise, cavitation, vibration and erosion. The CC trim range has been designed to operate on all fluid combinations, both clean and dirty service. The CC range of trims is normally the first choice for medium to relatively high pressure differential applications.

Multi Labyrinth Disk Stack (MLT) Range

Multiple stage disk stack design options. Developed to provide a high number of pressure letdown steps to provide ‘ultra low pressure recovery’ within the flow stream to minimise the potential for excessive noise, cavitation, vibration and fluid erosion. The MLT trim range has been designed to operate on relatively clean fluid combinations. The MLT range of trims is normally the first choice for extremely high pressure differential water injection to well applications.

CCD Range

Multiple stage disk stack design options. Developed to provide a high number of pressure letdown steps with ‘ultra low pressure recovery’ within the flow stream to minimise the potential for excessive noise, cavitation, vibration and erosion. The CCD trim range has been designed to operate on all fluid combinations, both clean and dirty service. This range of trims is normally the first choice for extremely high pressure differential dirty flow applications.

MP Concentric Cage (MP-CC) Range

Profiled plug with single and multiple heavy section ‘drilled hole’ cage (1CC to 3CC) design options. Developed to provide ‘low pressure recovery’, within the flow stream at the initial opening of the valve to reduce the potential for excessive noise, cavitation, vibration and erosion. The MP-CC trim range has been designed to operate on all fluid combinations, both clean and dirty service. The MP-CC range of trims is normally the first choice for low pressure production wells with relatively high TLP values where low pressure loss at full open provides increased well output performance.

Special customised trims utilising the various design features of the products within the range can be offered to suit any application requirement.

Severn Glocon is recognised by major operators as a global specialist in the design, manufacture and supply of severe service control and choke valves. Our valves are chosen by engineers who want the highest levels of reliable, long-term operation in severe service applications.
