Product Features:

• Operator – The ball valves can be supplied with a number of different operators, including Lever and Tee Bars for diver operation or paddles for ROV operation.
• Stop Pins – Each ball valve size has a stop pin designed for maximum torsional (Torque to Damage) strength.
• Anti-Blowout Spindle – All ball valves have an anti-blowout safety feature.
• Environmental Seals – All ball valves have seals to prevent the ingress of seawater. These have been tested to water depths equivalent to 10,000 feet (3050m).
• Gland Seals – The gland seal within each ball valve is a Peek thrust ring with a secondary o-ring with a special anti-extrusion ring designed to prove a leak-free spindle sealing with no requirement for adjustment.
• Seats – All ball valves utilise Peek seats which offer wide process compatibility whilst maintaining a positive sealing across the full pressure range from low to high pressure.
• Full Flow – Positive 90deg travel combined with clear through bore provides minimum restriction to flow.
• 2, 3 or 4-way Options.  – The trunnion mounted ball valves can be provided as either a two, three, or 4-way design.
• Traceability of Materials – All the components within an Oliver subsea ball valve have material traceability. The complete ball valves are individually serialised and are provided with material and pressure test certificates to BS EN 10204 3.1 certification and optional EN 10204 with the intent of 3.2 type certification option is also readily available (EN 10204 3.2 true mill witnessed shall be assessed for availability upon request).BS EN 10204 3.1 as standard, 3.2 optional.

Types of Ball Valve:

• 3/8″ Two-Way Trunnion Ball Type Subsea Valve
• This valve design utilises a trunnion mounted ball arrangement suitable for operating pressures up to 15,000psi (1034bar).
• The figure shows the valve with 1/2″ NPT connections, panel mounting holes and a square drive. The square drive is often fitted to a paddle or tee bar for ROV operation.
• 3/8″ Three-Way Trunnion Ball Type Subsea Valve
• The 3/8″ two-way valve can be fitted with an alternative ball design and bottom end connector making it so that fluid entering the bottom connection can be diverted to either of the two side end connections. Having double piston effect seats means that whilst flowing from the bottom connection to one of the side connections, the other side connection is fully isolated.
• Much like its 3/8″ bore sister product, the 1/2″ bore trunnion mounted ball arrangement is also suitable for operating pressures up to 15,000psi (1034bar). The figure shows a double sealing arrangement of the product. The double sealing valve utilises a spring energised gland seal in series with the normal o-ring spindle seal.
• 1/2″ Two-Way Trunnion Ball Type with Bolt-On Connections
• The 1/2″ ball valve can be supplied with bolt-on end connections rather than the threaded type. The bolt-on connections allow tubes to be welded below the valve rather than inline.
• This enables the distribution unit designer to fit a greater density of valves on their ROV panel.
