WhisperjetsÆ are designed for gas or liquid pressure reduction in new or retrofit installations. These devices reduce gas or liquid pressure through a series of multi-stage pressure reductions. As a result, there is virtually no part erosion. With gas applications, noise is significantly reduced because orifices on each stage are sized to keep the flow of the gas below critical velocity. Units are available in ASME pressure classes through 4500#, in sizes from 1/2" up, with socket weld or butt weld end connections. Depending on the application, standard materials are Carbon Steel A105 or Chromalloy SA 182-F22, F91. 316 and 347 Stainless Steel and other alloys are available upon request.
