Global quality. Total reliability. Two recurrent claims in present-day corporatestrategies. But the transition from wordsto actions demands tangible measures.Specialization and organization underliewhat amounts to a “quality culture” atBFE, not in the abstract but as a set ofspecific rules governing every stage ofproduction. An operating model that isgood to have in a partner who bears theresponsability of supplying valves that areessential to plant safety and regulation.

DEsigN, CoNstRuCtioN, MARKiNg FoR APi 6A vAlvEsBFE manufactures a complete line of quality API 6A valves, and can provide the exactvalves and actuators to meet the most demanding application requirements.Our API 6A valves are available in an extensiverange of designs, materials, sizes and pressureclasses and are in full conformance with APIand NACE specifications.All API 6A valves are designed in accordancewith API 6A and where applicable with ASMEVIII Div.1 and Div.The BFE family of API 6A valves provides positive shut-off of fluids and gases under extremeservice conditions.BFE uses only high-quality materials inspected &tested to International Standards and utilizes advanced manufacturing technology with specialemphasis on safety, quality, and long service lifeof our products, to ensure that our clients receivethe "best in class" products available from us ata competitive price and delivered on time.The forging material can ensure the best rigidity and strength under maximum rated operation pressure without inherent flaw of cast.Other properties found in forging includegreater impact resistance, resistance to fatiguecracking, particularly when cycling at eitherhigh or cryogenic temperature. Overdesignedwall thickness and adaptation of high strengthtie bolts are convenient for valve maintenanceand sufficient to bear the stress of pipe.The internal parts of valve are carefullydesigned and selected to ensure reliabilityunder all kinds of work conditions.Finite Element Analysis (FEA) is a veryimportant step of the development stageand ensures the best possible performancerequirements. Valves operational problems,pressure/temperature related deformationsand flow-related forces within a valve can beevaluated.BFE S.r.l. uses the FEA for predicting failuredue to unknown stresses by showing problemareas in a material and allowing designers tosee all of the theoretical stresses within. Thismethod of product design and testing is farsuperior to the manufacturing costs whichwould accrue if each sample was actually builtand tested.During any analysis project, it is the responsibility of the BFE analyst to verify that analysisresults conform to the physics of the problemunder study. Understanding the response ofa structure or manufactured product allowseffective design decisions to be made in developing structures and products that are functional, meet all engineering requirements, andcan be manufactured and assembled.Computational Fluid Dynamics (CFD) is usedto simulate operating flow conditions.Evaluation of Valve CV coefficient and convective heat transfer coefficient takes place at thedesign stage.von Mises (N/mmˆ2(MPa))- 414.0- 383.7- 353.3- 323.0- 292.7- 262.3- 232.0Since a variety of materials are available, BFEvalves can be used with various fluids and gases including petroleum based oils and extremesour gas service.- 201.7- 171.3- 141.0- 110.7FiRE-sAFE tEst APPRovEDBFE API 6A valves are designedin accrdance with API 607 & API SPEC 6FAwhere applicable.Full BoREThe full round bore design allows the fluidto flow through the valve smoothly withoutcausing turbulence and minimize pressuredrop. The absence of surface cavity eliminates the accumulation of foreign matterand allows passage of tools through thevalves.QuAlitY lEvElsQuality levels from PSL1 to PSL4 available.WiDE RANgE oF tRiM oPtioNsValve trims for any service, including H2S,CO2, high - low temperature and extremelycorrosive environments.iNsPECtioN AND tEstiNgEvery valve is subjected on a routine basisto different non-destructive testing, like dyepenetrant test on butt weld ends and on allhard faced and cladding areas.Non-destructive tests are also carried out onthe critical areas as defined by ASME B16.34.Optional examinations like:RadiographicMagnetic particiclesUltrasonicHelium leak testPersonnel performing NDT are trained andqualified to EN 473/ ASNT-SNT-TC-1A.Every valve is subject to a pressure test inaccordance with the standard API 6A.The rated pressure for the applicable pressure class is in accordance with API 6A.- 80.3- 50.0BFE API 6A Valve design is developed using thelatest software based analysis tools.At the design stage, all projects are analysedusing 3D solid modeling tools.Benefits include reduction of development timeand costs, improved product quality, and abilityto solve field problems for customers.Product flexibility and accuracy is assured.gENERAl MAiN FEAtuREsWiDE RANgESize and pressure ranges that meet or exceedthe requirements of API 6A, latest edition.

API 6A VALVE TYPES AND KEY FEATURESSLABGATE VALVE1. BFE slab-style gate is a simple one-piece & solid gate design, featuring metal to-metalseal between gate and seats, so as to apply to the most severe and demanding servicecondition, including corrosive and abrasive fluid environments.2. Non-rising stem design to permit smart valve installation.3. Full open through conduit construction to eliminate turbulence and pressure drop.4. Upper grease injection fitting to reduce the abrasion between gate and seats.5. Back seat with conical seal surface against stem allows stem seal replacement underpressure.6. Expanding gate design available on request.MUD SERVICEGATE VALVE1. Special Design made for high-pressure modern drilling mud systems.2. In the case of dynamic pressure lifetime of the trim designed according to the most severefrequency & amplitude conditions at 7500psi series with modern triplex mud pumps.3. Soft Seat maximal rating up to 7500psi. For API 10000 and above the applicable designis the slab type.4. Typical internal fluid types are mud, cement, fracturing and water service.5. High structural strength: All valves have the pressure retaining parts (Body and Bonnet)only in FORGED STEEL.6. Self energized packing. The Packing doesn’t require initial compression or periodicaladjustments.7. Quality level according to API 6A - PSL 1, 2 or 3.TRUNNIONBALL VALVE1. In the trunnion mounted design configuration, the ball is supported by bearing, held inposition by the valve closures. This configuration allows to discharge any side loads on thevalve body, enabling a smoother operation of the ball, minimizing the operating torque andreducing seat seal wear.2. Anti-Blow Out stem design.3. Standard seat design is single piston effect. Double piston effect sealing barrier availableon request.4. Antistatic device.5. Modular double block and bleed valves (two ball and a needle system) according to API 6Aare available on request.SWINGCHECK VALVE1. The closure element is a pivoted flapper which is swung open by flow and which sits againsta mating flat surface in the valve body, under no-flow conditions.2. Full bore and piggable design.3. Metal to metal and bubble tight sealing.4. Disc-Hinge center of mass designed as standard to allow horizontal or vertical installation.5. Best CV values produces the lowest pressure drop.6. Long service life.7. Special seal surfaces design for gas service (PSL 3G & 4).8. On Request external counterweights mounted on the hinge pin to increase or decrease thereaction time and speed of the disc returning to the closed position.
