Description
Firstly, 5X00481G01 eliminates cavitation by managing pressure drop, thereby eliminating damage. If the pressure drop of the entire valve can be controlled so that the local pressure never drops below the steam pressure, then steam bubbles will not form. If there are no steam bubbles collapsing, no cavitation will occur. To eliminate cavitation, a multi-stage valve core is used to divide the total pressure drop of the entire valve into smaller parts. Each of these small water droplets maintains its contraction chamber pressure above the steam pressure, so no steam bubbles will form.
The second method does not eliminate cavitation, but rather minimizes or isolates damage like using flash evaporation solution for 5X00481G01. This method aims to isolate the air pockets from the valve surface and harden the surface that the air pockets do affect. The third method is to change the system in a way that prevents cavitation. If P2 can be raised high enough so that the contraction chamber pressure does not drop below the steam pressure, that is, the valve is no longer blocked, then cavitation will be avoided. P2 can be raised by moving the valve to a position on the downstream side with more static head. The application of orifice plates or similar backpressure devices can also raise P2 at the valve; The downside is the possibility of air pockets transferring from the valve to the orifice plate.

Industry leaders use the International Electrotechnical Commission standard IEC 60534-8-3: Industrial-process control valves—Part 8: Noise Considerations— Section 3: Control valve aerodynamic noise prediction method. This method consists of a mix of thermodynamic and aerodynamic theory and empirical information.
The design of the method allows a noise prediction for a valve based on the measurable geometry of the valve and the service conditions applied to the valve. The standard also allows valve vendors to use laboratory measured empirical data within the framework to provide more accurate predictions. Because of this analytical framework for valve noise prediction the IEC method allows an objective evaluation of alternatives.
