The rugged and dependable SD- 1000 valve assembly features a straight through globe style body design with a single web internal construction. The high structural integrity, large interior flow passageways and large capacity bowl accommodate an extensive variety of trim designs, while allowing maximum recovery within the valve.

Applications for which the SD- 1000 valve is suitable include: pump recirculation, feedwater control, feedwater start-up, flashing or cavitating service and any potentially noisy or vibration prone service. It is also widely used for nuclear "N" stamp and seismic applications.
Copes-Vulcan offers the valve in a range of sizes between 20 and 500mm and ASME pressure classes from 150 to 4500 standard. However, large sizes can be supplied where applications demand. However, in designing the SD-1000, Copes-Vulcan have not overlooked the matter of that allimportant sub-assembly, namely the trim.
