High pressure drops can introduce severe erosion and wear. The Conval Whisperjet receives the high pressure inlet stream and discharges it through a series of multi pressure reduction stages called Whisperjets. Each Whisperjet section has four or six orifices around its perimeter. The orifices discharge inwardly, allowing the flow streams to impinge on each other rather than on the valve or sections themselves. These Whisperjets are designed to prevent sonic flow and critical pressure dropsmore

Additional Information

Additional Information

 Many power plants have replaced competitors' pump recirculation control valves with Conval valves equipped with custom-engineered Whisperjets. Why? Because the competitor valves' control velocity type trim limited mass flow and was causing the feed pumps to overheat. Today, the Clampseal®/Whisperjet valves are still operating flawlessly and are regarded as excellent, reliable products in what all agree is a difficult situation.

Whisperjets provide for the progressive increase in specific volume as pressure drops.
