High pressure drops introduce severe erosion and wear in normal servicevalves. The Conval globe valve receives the high pressure inlet stream.Discharge is through a series of multi pressure reduction stages calledWhisperjets. Each Whisperjet section has four or six orifices around itsperimeter. The orifices discharge inwardly, allowing the flow streams toimpinge on each other rather than on the valve or sections themselves.These Whisperjets are designed to prevent sonic flow and critical pressuredrops from occurring. By reducing the pressure in stages, cavitation,erosion, fluid velocity and sound level are minimized.
