Unlocking possibilities It is over 25 years since LB Bentley supplied the first small bore valve with API specification to the subsea industry. Over these years we have continually developed our valves in line with the customers requirements, they are designed to satisfy the applications and the environments in which they are being used. Today, exploration is heading into remoter locations with deeper waters and more extreme conditions. Accessing reserves is becoming more challenging than ever before. In order to enhance recovery rates cost-effectively, operators rely on their hardware. Reliable valves are a vital component of hardware requirements. With our extensive experience, we have the edge when it comes to designing and developing small bore subsea valves. LB Bentley has the unique advantage of being the first manufacturer to produce small bore valves to the required industry specification. The volume and success of our small bore valves delivered to projects globally gives us the confidence of knowing that our products and processes are robust and quality driven. We pioneered metal-to-metal sealing technology that reduces the risk of contamination and failure, a technology we continue to use in our newly developed products. Our valves undergo rigorous testing, over and above industry requirements. This includes a 600-cycle or 1,200-cycle lifecycle test programme (opening against full rated differential pressure) with low and high pressure gas testing to API 6A PSL 3G before and after cycling. Valves are compliant with current design and testing principles, including API 17D 2nd edition, with temperature qualification being extended to 150 C (300 F). We employ some of the brightest minds in the industry to stretch the boundaries of design with creative engineering. The outcome is bespoke products that help engineers solve their design challenges. We like to think of it as a partnership approach, working closely with our customers. LB Bentley continue to move forward with the changes and challenges within the industry by building on our past experience to develop new products and deliver expert solutions. DEVELOPMENT OF SMALL BORE SUBSEA VALVES
Engineered for reliability With many years experience of delivering robust and reliable products, many to SIL2, to satisfy the requirements driven by a harsh environment, our valves offer optimum safety and performance. Rotary and through conduit gate valves benefit from metal-to-metal sealing. Robust, compact design, coupled with special assembly options ensures our products are optimised for subsea applications. Rotary gate valves Our rotary gate valve is beautiful in its simplicity. A 100% continuous metal-to-metal design ensures it performs reliably even with the dirtiest of fluids. The valve s innovative wiping action between the gate and buttons means it is self-cleaning, which further promotes longevity. It has minimal moving parts and a time-saving quarter-turn mechanism that can be operated manually or with hydraulics. Even in the event of over-torque in the open or close position, internal components cannot be damaged; the valve will continue to rotate. One valve can suit multiple applications, from isolation to block before/after bleed to diverter. A no-volume displacement design makes the product less sensitive to water depth. The rotary gate valve is both manual and hydraulic. Our purpose built actuators are designed to cope with any demands that our valves are exposed to. Our innovative OPTItork TM actuators are available to operate 3/8" to 3/4" LB Bentley Rotary Gate Valves at differential pressures of up to 15,000psi (1,034bar). The OPTItork TM actuator operates to a performance level unmatched in the industry. A wide range of operating pressures, working pressures and operating temperatures can be catered for. Porting and mounting arrangements can be tailored according to need. Body size, stems, seals and ROV interfaces can be rationalised if required. Sizes and pressures 3/8" up to 10,000psi 1/2" up to 15,000psi 3/4" up to 15,000psi 1" up to 10,000psi Rotary gate valve 02 Subsea product overview
Through conduit split gate valves Custom-designed for use on subsea Christmas trees, manifolds, pumps and pipeline equipment, our through conduit gate valve range is ideal for restricted areas. Where a through conduit valve design is required to have full metal-to-metal sealing throughout the flow bore, LB Bentley can provide a product that is truly unique in the market place. Patented static leaf spring design ensures that the split gates are pre-loaded against the seat face. The pre-load is applied to the gate at the centre line of the seat so that seat/gate contact is maintained at all times. This enables a low pressure gas-tight seal to be achieved without the aid of a lubricant or sealant injection. The valve is available in both 1/2" and 1" sizes, in FF and HH trims, pressures of up to 10,000psi, temperature range 29 C to 121 C and qualified to water depths of 8,500ft. It is available in both actuated and manual configurations. Applications include methanol and chemical injection, annulus wing valves, test lines or pressure/temperature transducer isolation. A full range of accessories are available including ROV buckets, extension rods, compensator, indicator mechanisms etc, together with the option of incorporating the valve assembly into manifold arrangements. Sizes and Pressures 1/2" up to 10,000psi 1" up to 10,000psi Service Our valves are designed to accommodate control fluids, well fluids containing H 2 S/CO 2 gas, injection chemicals and methanol.

Check valves Check valves can be supplied with welded, flanged or threaded connections, as standalone units or integrated with through conduit or rotary gate valves. LB Bentley s check valves are built to fully satisfy the testing priciples and requirements of API 17D 2nd edition. The spool-to-body primary seal is metal-to-metal, with a PTFE secondary seal. Lift pressures can be customer specified typically 1 to 4 bar. Integral check valves can also be built into the valve inlet or outlet to provide a double barrier against the well fluid. Sizes 1/2 inch 1 inch Supporting products We understand the challenges of subsea production, and push boundaries to deliver intelligently engineered, bespoke small bore valves. Stem Extensions Where the design of the XMT demands the need to overcome space envelope challenges, we have the ability to design and build bespoke extra long stem extensions enabling ROV access to a valve placed deep within the XMT. Compensators Where necessary, we can provide purpose-designed hydraulic compensators. They connect directly to the actuators without the need for external pipework, they use a rolling diagphragm that delivers a displacement function if a sea chest is not available. ROV Receptacles ROV receptacles can be supplied in all the usual interfaces, i.e. ISO 13628-8 Class 2, 3 and 4, High Torque Low Torque or pesonalised to particular customer requirements or specifications. They may be integral to the valve or actuator, fitted at the end of a stem extension or supplied as a stand alone unit. A wide range of applied coatings are available to suit customer or project requirements, in either paint or xylan finish with the colour matched to most RAL numbers. 04 Subsea product overview
Facility & Capability All design and manufacturing takes place at our UK 5,700m 2 purpose built facility. To enhance the quality and service delivered to our customers, over the last few years, LB Bentley has invested in not just state of the art manufacturing machinery and equipment but has been committed to developing our in-house expertise and specialist software. Our capabilties include Visual ERP system which is integrated throughout the manufacturing process. This delivers accurate scheduling and planning CNC Machine Shop highly experienced with exotic materials such as Duplex, super Duplex, and nickel alloys CNC, CMM, 3D Solid modelling CAD System with CAM implentation, FEA 13 High Pressure Test Cells with the ability to deliver remote witness testing Research & Development The can do attitude of our R&D department reflects our belief that there is always a better way. With departmental experience stretching back to the 1970 s blending with younger employees, the status quo is always being questioned and challenged. Whilst most of the Qualification testing is performed in excess of industry standard requirements, wherever possible testing is also carried out in a manner that replicates field operating conditions as closely as is feasible. This is done to provide customers with total confidence in the reliability of the product. In recent years, the number of R&D test cells have doubled, allowing LB Bentley to develop and implement new and improved products. The capabilities and boundaries of existing products are constantly being explored and re-defined, whilst the opportunity to evaluate new concepts is also being exploited. To speed the test cycles, automation is increasingly utilised, which, coupled with electronic acquisition of the data allows detailed and rapid analysis and evaluation of results. Improvements in materials, coatings and designs are evaluated in smaller feature proving satellite tests prior to incorporating them into new or enhanced products. To ensure that testing is clearly focussed and directed, engineering analysis is used to simulate numerous what if scenarios, thus achieving increased efficiencies throughout the development cycle.
