3 PRESSURE TESTING - GAS TESTING TECHNICAL All twinsafe valves are tested in accordance with our own in house high performance test specifications, which operate above and beyond the tests required in ANSI B16.34, API 598 and API 6D, thus ensuring the customer receives the highest standard of products. Oliver Twinsafe Valves has invested in the state of the art test stations to allow larger valves to be tested easily, accurately and quickly. Gas test facility available. CE MARKED VALVES STANDARD 10 Oliver Twinsafe Valves is a world leading manufacturer of high performance double block and bleed twinsafe units with an unrivalled reputation for innovation, product development, quality and service. With a rapidly expanding manufacturing facility and a comprehensive network of marketing and distribution outlets across the globe, the company is able to offer outstanding support to our customers worldwide All Oliver Twinsafe Valves above 1 nominal pipe size are CE marked in accordance with the European Pressure Equipment Directive 97/23/EC and satisfy the essential safety requirements contained therein. Firesafe (FS) Fire tested to API 607 REV4, API 6FA, BS 6755 PT 2 Design Products comply with the relevant code requirements of API 6D, ASME Vlll and ANSI B Geared Handwheel Operation Generally valves above 2" 1500 class are supplied with gear box operator. Double Block & Bleed valves fitted with two gear box operators are supplied with one removable handwheel as standard. This allows operation of one isolate at a time, for safety. Please consult factory. Valve Marking Marking of ball valves to MSS-SP-25 and EN19 standards. NACE (NA) As standard, the full range of Oliver Twinsafe Valves are compliant to NACE specification MR (latest revision) Sulphide stress cracking resistant metallic materials for oilfield equipment. Testing Each valve product is individually tested both hydrostatically and pneumatically as follows: Hydrostatic shell test to 1.5 x full rated pressure, and hydrostatic seat test to 1.1 full rated pressure, and a low pressure, pneumatic seat test to 80psig. Certification and Traceability All valves exhibit unique identification coding and material test certificates to BS EN B as well as lifetime factory history being available. Development Continual development maintains the highest levels of performance and integrity for our Double Block Twinsafe valves. Oliver Twinsafe Valves maintains in-house performance and fire test facilities. Painting Carbon steel valves can be supplied with a range of external coatings for environmental protection. Please consult factory Temperature Standard temperature range is -30 C to 150 C in accordance with API6D and higher temperatures with metal seated valves, consult factory for higher temperatures. Explosive Decompression Explosive decompression occurs when gas at high pressure permeates into seal materials. When the gas pressure is reduced the absorbed gas expands, which can cause the seals to swell and blister. Oliver Twinsafe Valves only use seal material within their twinsafe valve range that are resistant to explosive decompression. Pressure Equipment Directive Valves conform to the European pressure equipment directive 97/23/EC 3

4 TECHNICAL METAL SEATED BALLS Geared Handwheel Operation (GO) Reduction gearing to turn the ball valve through 90 degrees is available, with watertight casing to IP65 protection rating, as strengthened and helicoidal gearing, complete with mechanical position indication. De-clutchable manual override gear box and high ratio gear boxes for greater torque output are also available, please consult factory. Valve Actuation On one or both of the valves, double acting and spring return, pneumatic or hydraulic actuators are available, limit switches and open and close indication can also be specified. Please consult factory Seat Injection This is an option, please specify full details to factory. Spindle Injection This is available on 2" trunnion mount and above, please specify full details to factory. Painting Any painting specifications or indeed plating specifications can be reviewed at the time of enquiry. Cavity Relief Any undesirable build up of pressure in the ball cavity is relieved automatically past the sprung seat design on trunnion mount balls For cavity relief of the vent cavity a PSV (Pressure Safety Valve) or external relief valve can be located either directly opposed to the vent port, or as part of the vent valve (PSV is supplied by third party). OPTIONS Vent Valve A vent connection in conjunction with a vent valve of either a ball type or needle valve type are available with various bore sizes of each, the vent connection may be flanged or threaded.
