From the catalogue's introduction to this valve type: GENERAL PRODUCT FEATURES API 6A VALVE DESCRIPTION API 6A standard were initially developed to cover all christmas tree and wellhead equipments but today they are used for a large part of the upstream oil and gas industry. Valves covered by this specification are in general components for use in upstream oil and gas exploration, production and incorporate all the activities associated with the installation of this equipment. They can serve the purpose of providing a control mechanism while taking returns during drilling operations or they can also be used during other operations, including gas lift and well kills. Equipment ranges from 2000 to 15000 psi working pressure and in general the design can includes single or multiple completions, high and low temperatures and all types of service conditions. 6A valves general features include in-line repairability, protected long-life seats and sealing without lubrication. Native 6A design include gate, ball, swing check and piston check. Users in general request gate valves with full bore and thru-conduit design, non-rising stem, slab gate, floating seat ring body bushing design to provide safe dependable service. Ball valves are in general trunnion mounted type only. Industry requiremens for API 6A product are the most severe: reliability, high efficiency, only trusted components can normally be considered. PRODUCT FEATURES 1. Standard construction of body-bonnet (or closure for ball valves) connections is bolted type. 2. Full die forged structure for all pressure containing parts. 3. Flanged valves are provided with flanged integral with the body forgings. 4. Standard body-bonnet gasket design is ring joint type. 5. High quality packing for reliable tightness and low emission performance. 6. Sealing surfaces are machined to the tightest tolerances and lowest roughness to ensure reliable sealing & long service life. 7. Best-in-Class CV values. 8. Inside screw API 6A typical design available. 9. Low operation torque design. 10. Temperature ratings from K to V, special low tomperature application and high temperature design acc.to API 6A - Annex G on request. 11. Material class from AA to HH, .ost common covered services are sweet/ general, sour/NACE, steam, CO2, water flood, mud, corrosion resistant alloys (CRA). ISNRS SLAB GATE VALVES • Non-rising stem design to permit smart valve installation. • Full open through conduit construction to eliminate turbulence and pressure drop. • Simple one-piece, forged & solid closure member design. • Body cavity self relieving design. • Metal-to-Metal sealing. • Shear Pin that protect the valve from damage due overtorque. • Metal backseat with conical seal surface against stem allows stem seal replacement under pressure. • Upper grease injection that provides access for lubrification of the steam area and provide a means to verify the backseat seal. • Bi-Directional design. EXPANDING GATE VALVES • Outside Screw and Yoke design (OS&Y). • Positive Sealing (Capability of improving seal tightness by increasing the stem thrust). • Double seal (both up and downstream seats contribute to guarantee tight seal). • Tight mechanical seal regardless of service pressure variations. • Double block and bleed capability. • Metal back seat with conical seal surface against stem allows stem seal replacement under pressure. • Bi-Directional design with preferred flow direction. OS&Y SLAB GATE VALVES MUD SERVICE GATE VALVES • Special Design made for high-pressure modern drilling mud systems. • In the case of dynamic pressure lifetime of the trim designed according to the most severe frequency & amplitude conditions at 7500psi series with modern triplex mud pumps. • Soft Seat maximal rating up to 7500psi. For API 10000 and above the applicable design is the slab type. • Typical internal fluid types are mud, cement, fracturing and water service. • High structural strength: All valves have the pressure retaining parts (Body and Bonnet) only in FORGED STEEL. • Self energized packing. The Packing doesnít require initial compression or periodical adjustments. • Quality level according to API 6A - PSL 1, 2 or 3 only (no gas service). SIDE ENTRY & TOP ENTRY TRUNNION BALL VALVES • Standard double block sealing performance. • Full die forged structure for all pressure containing parts. • Flanged valves are provided with flanged integral with closure member. • Standard primary gasket design is OR AED type, secondary emergency seal always provided for fire-safe purpose. • High quality stem gasket for reliable tightness and low emission performance. • Use of low seat-ball friction materials and surface finish for reliable sealing and long service life. • Best-in-Class CV values. • Standard split & bolted design for body-closure connection. • Low operation torque design. • Static conduction spring is used as standard between the stem and the ball (Antic-Static Device). • Anti blow-out proof stem design. SWING CHECK VALVES • Center-of-gravity location of the disc and swing arm assembly designed in order to minimize pressure drop and suitable for vertical installation as standard: the valve will return to the closed position should flow become interrupted or reversed even with vertical installation (flow must be in an up-flow direction). • Internal hinge pin design eliminates additional leakage points. • High flow capacity port sizes and disc retraction to minimize flow velocities and maximize valve service life. • Design of disc and hinge assembly to generate a closing moment to provide adequate closure and sealing at low pressures. • Sealing surfaces are machined to the tightest tolerances and lowest roughness to ensure trouble free shut off and cycling. • Low cracking pressure design. • Swing check nut positively secured to prevent disassembly during service by permanent cold deformation of the closure member. No additional cotter pin or other small parts are used as locking system. "T"-PATTERN PISTON CHECK VALVES • Sealing surfaces are machined to the tightest tolerances and lowest roughness to ensure trouble free shut off. • Body-guided disc for perfect seat and disc alignment. • Disc is machined to the tightest tolerances to ensure trouble free shutoff and cycling. • Precision guided closure member for perfect seating surfaces alignment. • Closure member can be spring loaded for positive closure in any position. • Fast response time to prevent backflow and adequate valve seating to prevent seat slamming.
