Description
SDTCS gate valves are full-bore isolation valves of the through-conduit type: a one-piece body with a single bolted bonnet, a rising stem and floating metal seats with soft face sealing. In the open position the gate bore aligns with the pipeline bore, forming a smooth channel without pockets or restrictions, so the valve passes cleaning and inspection pigs (piggable) and creates practically no pressure loss. Design standards are API 6D, API 6A and ASME B16.34. The range is from 2 to 68 inches to ASME classes 150–2500, and from 1 13/16 to 11 inches to API 6A at pressures of 2000–15000 psi; operating temperatures from −196 to +400 °C. Face-to-face length is per API 6D, API 6A or the manufacturer’s standard. The valve is bidirectional, with energized seats; the standard arrangement is self-relieving seats (SPE×SPE). It has an anti-static device, a stem protected against blow-out, and a fire-safe design. Seats are made of metal with tungsten carbide or chromium carbide coating, or with inserts of Devlon V, PEEK or PCTFE. Seals: metal BX ring gasket, graphite, lip seals, chevron V-packing and O-rings. Fasteners: ASTM A193 B7/B7M, A320 L7/L7M, B8/B8M, duplex UNS S31803, super duplex UNS S32760, A453 Gr.660. Soft seats are standard and metal seats are available on request; an extended stem and bonnet, welded end connections, surface overlay, and compliance with NACE, PED and ATEX are also available on request. Connections: flanges ASME B16.5/B16.47 and 6B/6BX per API 6A, butt-weld ends (ASME B16.25), hub and compact ISO 27509 flanges. Operation ranges from manual gearboxes to hydraulic or pneumatic actuators designed to the project. The manufacturer lists the application areas: pipeline transport, onshore and offshore production, FPSO, LNG terminals and oil refining. At high-pressure gas facilities, gate valves are installed on the linear section of gas pipelines, in pig launching and receiving chambers, on manifolds and well flowlines, and at the inlet of gas distribution stations.
