Whisperjet reduction devices (photo) reduce liquid or gas pressure through a series of multi-pressure reduction stages. Designed for new or retrofit installations, these simple, long-lasting devices result in virtually no part erosion. With steam applications, noise is significantly reduced, because orifices on each stage are sized to keep the flow of steam below critical velocity. Whisperjet devices are available in conjunction with Clampseal globe valves or as standalone equipment, in ASME pressure classes up to 4500#, in sizes½ in. and up, with socket-weld, butt-weld or flanged connections. Depending on the application, standard materials are carbon steel A105, Chromalloy SA 182-F22, F91 and 316/316L stainless steel. Optional materials and end connections are also available. — Conval, Somers, Conn.
