Liquid & Gas Reduction Valves


Custom Whisperjet liquid and gas reduction valves are ideal for new or retrofit installations.


The simple, practical, long-lasting devices reduce liquid or gas pressure through a series of multi-pressure reduction stages. As a result, there is 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.
