High-viscosity process valve

Homogenisation processes now extend up to 1500 bar differential pressures. As the materials to be homogenized exhibit varying properties with respect to viscosity, corrosiveness and abrasiveness the high pressure components, such as homogenising pumps and valves, need very careful design and choice of materials. 

In commercial homogenization valves, turbulence and cavitation dominate droplet disruption. Here, droplets of a low viscosity are more easily deformed and disrupted than droplets of higher viscosities. Therefore, the overall equation describing the process functions for high-pressure homogenization processes is... 

Uther information required for either liquid or vapor contnil valve are maximum and miniiBiim inlet pressure, oontioi valve shut off pressure, maximum and minimum inlet temperature, corrosive nature of the process fluid, any. solids or contamfnante present ir pirocess fluid, and viscosity of fluid (especialJy for high viscous fluid).
