DBB Pipeline Ball Valves

Trunnion Ball Valve DBB Flanged 3 Piece Design

Our Flanged Style Double Block & Bleed Valves are designed with a bolted 3 piece body and conventional through bolting flanged connections. The design reduces potential leak paths and allows weight and space savings when compared to conventional piping methods. Available in both full and reduced bore sizes.

Product Information

  • The 3 piece bolted construction provides conventional through bolting of the flanged end connections, plus the option of hub or welded ends. The overall lengths of the valve are kept to a minimum and offer considerable cost, weight and space savings over conventional piping methods of double block and bleed, using separate ball valves and spool pieces.
    Valves are available with full bore sizes in accordance with API 6D, ensuring maximum flow for increased production rates and allowing pigging of the pipe line.
    The integral trunnion plate design reduces leak paths through the body.
    Various bleed valve options and connections are available in line with customer requirements

    Available up to 16″ full bore (larger sizes on request).
    Trunnion mounted design from 2″ to 16″.
    Flanged connections in accordance with ASME B16.5 or API 6A, hub connectors or welded ends also available.
    Integral vent valve with both threaded and flanged connections available.

Compact Ball Valves

Compact Ball Valves

Oliver Twinsafe provides Compact Style Ball Valves that are designed to provide considerable space and weight savings when compared to a traditional flanged end ball valve.

Thanks to our high-integrity design, we have supplied valve solutions to global customers for many years, custom-built to their individual requirements. Compact Ball valves have proven their worth in many applications.

Available in both floating and trunnion ball designs, the valve utilises Oliver’s proven ball valve technology and can be supplied with either manual or automated actuation. Oliver Twinsafe works with customers globally to engineer and manufacture precision Compact Single Valves.

Product Information

  • The design features include;
    • Bi-Directional Ball Valves with soft or metal seats.
    • Swivel flange type construction, with butt weld pipeline connections.
    • Floating Ball or Trunnion mounted design.

    Compact Light-Weight Design
    Provides space and weight saving on platforms, reduced shipping and handling costs and minimal structural support.

    Threaded Valve Insert
    Designed to take full working pressure, which does not rely on the mating flange to hold internals.

    Oliver Swivel Flanges
    Designed to allow hubs to be welded into line before split rings and flanges are fitted. The valve can be fitted with no additional ‘springing’ of pipework.

    Firesafe Design
    O-ring seals and metal-to-metal contact on all static joints, graphite rings provide additional resistance to leakage in the event of a fire.

    Other Design Features
    Anti-blow out stem design shouldering on the body (rather than the bonnet), Automatic cavity relief, Low friction dry stem bearings to minimise operating torques and maximise cycle life. Valves can be supplied with a mounting plate in accordance with ISO 5211 for actuator attachment.

    All of the Oliver Twinsafe Valves are tested following our in-house high-performance test specifications, ensuring that our customers receive the highest standard of product.

DBB Pipeline Ball Valves

DBB Pipeline Ball Valves

Oliver Twinsafe produces a range of Trunnion Ball and Floating Double Block and Bleed Valves. We offer true double isolation with two independent ball valves contained in one valve body, guaranteeing absolute shut-off and maximising the safe operation of any processing facility.

Product Information

  • Modular Double Block and Bleed valves from Oliver Twinsafe are designed to offer one valve solution, available in most sizes to fit in the same space as a single ball valve or with the shortest possible face-to-face dimension. This compact design saves weight and space and reduces costly installation charges, whilst providing true double isolation for maximum safety and reduced process problems due to valve leakage.

    The key benefits of the Oliver Twinsafe Valves are:

    • Space-saving – ability to replace single isolate valves with a true double block and bleed valve, but within the same overall length, ensuring that expensive pipework modifications are kept to an absolute minimum.
    • Weight-saving – compared to a conventional Double Block and Bleed hook up of two separate ball valves with a central spool piece and vent valve, weight savings can be over 50%.
    • Increased Safety – compared to a conventional Double Block and Bleed arrangement using separate valves, the number of potential leak points is greatly reduced.
    • Cost-saving – fewer items to purchase and expedite means overall cost savings, plus lower installation and maintenance costs.
