Description
TE ball valves are valves with a ball on trunnions and top entry: a one-piece body with a single bolted bonnet. The ball is supported by parts fixed in the body, so pressure loads are transferred to the body, the ball turns smoothly with low torque, and seat seal wear is reduced. The main advantage of the design is full in-line maintenance: access to the ball, seats and stem is through the bonnet, so the valve can be welded into the pipeline without losing the possibility of later repair. The bodies of such valves are usually cast. Design standards are API 6D, API 6A, CSA Z245.15 and ASME B16.34. The range is from 1/2 to 48 inches (to API 6A from 1 13/16 to 21 1/4 inches), ASME classes 150–2500 and API 6A 2000–15000 psi, operating temperatures from −196 to +400 °C. Face-to-face dimensions are per ASME B16.10, API 6D and API 6A, and for classes 150 and 300 the dimensions match class 600, which simplifies standardization. The seats are floating with spring preloading, the ball and stem are independent, and the bearings are reinforced. The valve provides double block and bleed with bidirectional sealing, has a fire-safe design, an anti-static device and a stem protected against blow-out. The bore is full or reduced. 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; body and seat seals: FKM, HNBR AED, FFKM O-rings, PTFE lip seals with Elgiloy spring, graphite packing. Fasteners: ASTM A193 B7/B7M, A320 L7/L7M, B8/B8M, duplex and super duplex, A453 Gr.660. Connections: flanges ASME B16.5/B16.47 and 6B/6BX per API 6A, socket weld (ASME B16.11) and butt weld (ASME B16.25), threaded, hub and compact ISO 27509 flanges. According to the catalogue, some top-entry valves have been supplied for vertical installation, with internal liners for flushing the line without damaging the seals, and in versions with metal seats. Applications: trunk gas pipelines, LNG terminals, FPSO, onshore and offshore production, oil refining, power generation.
