There are some terms highlighted in the Flowserve Control Valve sheet that I wasn't able to grasp. Valve is liquid servicing
The inlet pressure is ~13 barg where as Choked Drop is ~0.2 bar ( I do have understanding of choked pressure)
On 2nd page there is a weird term Detailed Cavitation (Sigma) information? What is this & how is it useful?
