With over 50 years’ experience, the Severn Glocon Group plc provides world-class engineered valve products and services to process plants across the globe. The Severn Leeds brand is recognised globally for innovative butterfly valve solutions for critical shut off and control applications. With sizes from 2" (50mm) to 100" (2500mm) and beyond, materials from cast iron to exotic alloys, pressures up to 2500# and with a temperature range from cryogenic to over 1800F (>1000°C), the Severn Leeds Valve range is tailored to give optimum performance and reliable service life for even your most arduous applications.
STANDARD DESIGN FEATURES
Size range – 2" to 100" (larger on request) Valve pressure ratings 150# to 2500#
Materials – Cast iron, carbon steel, stainless steel, Duplex and Super duplex, bronzes, Monel™, Inconel™, Hastelloy™, Titanium
Linings – refractory, metallic overlays, stellite
Seals – Metallic, TFE and ElastomericOperation – bare shaft, manual, pneumatic, electro-hydraulic, hydraulic or electrical
Note: All valves are designed to meet international standards for face to face drilling and end connections. Bespoke dimensions available on request.
HIGH PERFORMANCE TFE & METAL SEATED BUTTERFLY VALVES
• For critical shut off and control applications
• Extensive range of body and disc materials ensure optimum corrosion resistance
• External bearing design options reduce the danger of valves jamming where there is risk of media solidification
CRITICAL CONTROL BUTTERFLY VALVES
• Cavitation and noise reduction trims improve valve performance and longevity
• Integral baffle plate designs for high pressure drops, also with retrofit capability
• Temperature stability optimisation with integral steam jacket options
SWING CLEAR & STEP SEAT CONTROL VALVES
• Simple design for minimum weight and maximum cost efficiency
• Suitable for high temperatures up to 800°C
• Equal percentage characteristic gives excellent control throughout its span
EXTREME TEMPERATURE VALVES
• Sizes up to 100” to suit even large diameter hot gas systems
• Refractory lining acts as an insulator, helping to avoid unwanted heat loss
• Disc designed to ensure smooth, low torque operation, irrespective of temperature
LARGE DIAMETER VALVES – LINED & DISC SEALED
• Lining and disc materials optimised to increase corrosion life
• Designed to meet all standard face to face requirements including AWWA (American Water Works Association)
• Ideal for seawater and brine applications, such as desalination or power station cooling
CRYOGENIC & AIR SEPARATION VALVES
• Assured sealing in excess of BS6364 Standards
• Advanced seal ensures seat area is always loaded throughout temperature range
• Valve design ensures low seating and breakout torque to avoid jamming risk
A commitment to process understanding, ensuring the optimum valve, whatever the application
All materials are selected to give excellent corrosion resistance and maximum service life
