Severn’s 8300 Double Offset High performance Butterfly Valve Series enables the disc to achieve a uniform 360°C seal contact and to move into and break out from the seat with the minimum of wear.

The seat design ensures low seating and breakout torque, resulting in smaller actuators and improved economy when selection from the various forms of actuation available.

Across the size range, the 8300 Series has a variety of distinct features, all designed to reduce wear and control effectively to support durable performance, ensuring you meet your core imperatives of safe operations and minimum downtime.

Design Features:

• Self energising seat at low pressure
• Pressure energised at high pressure compensating for wear and temperature
• Seat energiser fully isolated by PTFE envelope
• Cavities minimised to avoid ingress of particulates
• Temperature ratings from -196°C to +230°C
• Shut off pressures up to 100 bar
• The quarter turn design ensures ease of actuation for both control and on/off duties
• Standard face to face dimensions to API 609 / ISO 5752 and B16.10 with non-standard dimensions available on request
• Valve size range – 2in (50mm) – 48in (1200mm) with larger sizes available on request
• Body pressure ratings up to 2500lb
• Can be manufactured in all commercially available metals in cast, forged or plate form
• Non-graphite options available for seawater service
• Anti-blowout stem as standard on #300 ratings and above

Benefits

• The double eccentric action enables the disc to achieve a uniform 360°C seal contact and to move into and break out from the seat with the minimum of wear

• The seat design ensures low seating and breakout torque
• Anti-cavitation trims and baffle plates available to reduce cavitation and noise issues

Severn’s Cryogenic Butterfly Valve range is developed from years of Control Valve knowledge and experience.

We have developed our 8300 ranges for cryogenic applications. Open or closed extension bonnets are available for all our valve products, ensuring the gland packings are located away from the line media.

By utilising the principles of our 8100, 8300 and 8500 valve ranges, we can offer a vast range of products from a Single Offset Swing Clear valve, a Double Offset PTFE Seated valve, or a Triple Offset valve, all specifically tailored for cryogenic services.

Clients can also choose from standard and bespoke face to face and end connection options. With access panels available on Butt Weld End designs when required.

Severn’s 8300 Cryogenic Butterfly valve series offers the flexibility in design for assurance in performance and ensures you maintain and achieve your core imperative of safe operations and minimum downtime.
