Description
Deltaflux is a control ball valve for controlling and modulating the flow and (or) differential pressure of the medium in a pipeline. The valves are made for the specific task and are used from the traditional sectors of the oil and gas industry, namely production, transport and processing, to renewable energy installations. The valve is especially suitable for duties that combine a large differential pressure with large flow rates. These are wellhead control, gas treatment and gathering plants, compressor stations, blowdown and anti-surge control units, and withdrawal and injection lines of underground gas storage.
The profiled quarter-turn trim gives a high flow coefficient Kv and minimal pressure losses in the fully open position, so the valve combines flow capacity with a wide control range. The profile of the element is selected for the specific line and the given operating modes.
The pressure class is ANSI 150–2500, the design temperature is from −196 to +425 °C, and the sizes are from NPS 2″ to 48″ (DN 50–1200). Connections are RF and RTJ flanges per ASME B16.5, B16.47 and MSS SP-44, butt-weld ends per ASME B16.25 or hub connections per the customer specification. The face-to-face length follows ASME B16.10, the manufacturer's standard or the customer's requirements, and the actuator mounting pad is made to ISO 5211.
The side-entry body is bolted or welded, and a top-entry version is also available. Operation is by bare stem or by an actuator (pneumatic, hydraulic or electric). The metals include carbon and low-temperature steel, stainless, duplex and super duplex steel, and special alloys. The soft parts are made of RPTFE, PEEK, the elastomers FKM, FFKM and HNBR, and graphite. Coatings are electroless nickel plating, 316SS or N06625 weld overlay, and HVOF spraying with tungsten or chromium carbides. Not all combinations are available, so the configuration is agreed with the manufacturer.
Product certification covers API 6D, API 6A, API 6DSS and IEC 61508 SIL 2 functional safety. Management systems are certified to ISO 9001, ISO 14001 and ISO 45001. Fire resistance is confirmed per API 607 and API 6FA, and fugitive emissions per ISO 15848-1.
