Introducing custom-designed, low-cost Whisperjets® for gas or liquid pressure reduction, for new or retrofit installations. These simple, long-lasting 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. Whisperjets are available in ASME pressure classes through 4500#, in sizes from 1/2" and up, with socket weld or butt weld end connections as standard and other ends available upon request. Depending on the application, standard materials are Carbon Steel A105, Chromalloy SA 182-F22, F91. 316 and 347 Stainless Steel and other alloys are available upon request.
