Description
EB ball valves with a ball on trunnions and side entry are the basic design of the range. The body is in two or three bolted parts and is usually made of forgings. The ball is supported by bearing plates that hold the end adapters, so pressure loads are transferred to the body; the ball turns smoothly with low torque, and seat seal wear is reduced. The ball and stem are independent, the bearings are reinforced, and the valve is suitable for horizontal and vertical installation. Design is to API 6D, API 6A, the Canadian CSA Z245.15 and ASME B16.34. The EB model covers diameters from 4 to 68 inches (to API 6A from 2 9/16 to 21 1/4 inches), ASME classes 150–2500 and API 6A 2000–15000 psi, temperatures from −196 to +400 °C. For small diameters the EC model is produced, from 1/2 to 3 inches (API 6A 1 13/16–3 1/8 inches), with the same pressure and temperature range. The seats are floating, with spring preloading. The standard arrangement is self-relieving seats on both sides (SPE×SPE); on request, double piston effect (DPE×DPE) or a combined arrangement; the design provides double block and bleed and bidirectional sealing. Seat inserts: FKM (Viton A/GLT/AED), HNBR, PTFE/RPTFE, nylon/Devlon V, PCTFE (Kel-F), PEEK, or metal with tungsten carbide or chromium carbide coating not less than 0.15 mm thick. Seals: FKM, HNBR, FFKM O-rings, PTFE lip seals with Elgiloy spring, graphite. Body materials: carbon and low-temperature steel, high-strength steels A694 F52–F65, stainless steel, duplex, super duplex, 6Mo, Inconel 625, Incoloy 825, Monel. The design is fire-safe, with an anti-static device and a stem protected against blow-out; drain and vent fittings are standard. Options: emergency sealant injection to the stem and body, extended stem and bonnet, welded end connections, overlay of sealing and wetted surfaces, FBE coating, compliance with NACE MR0175/MR0103, PED 2014/68/EU and ATEX 2014/34/EU, compact design, V-port ball for control, cryogenic and high-temperature versions. Cryogenic valves are fitted with an extended bonnet with a vapour space that protects the stem seal from the cold fluid. Applications: gas pipelines, LNG terminals, onshore and offshore production, FPSO, processing.
