Hi,
I am currently in technical clarifications regarding a new 3-way globe valve. The valve will have two operating cases:
1- Full flow: Where the fluid flows 100% through the valve without diversion
2- Partial flow: Where 50% of the flow is diverted and the remaining 50% flows through the valve
It's a globe valve
The vendor has submitted their calculations and came back with Cv bigger than the one I calculated using ISA 75.01.01 (2012). I double checked my calculation using our company's software and all is in line with my calculation.
I believe I should accept the vendor's calc. Any thoughts/recommendations?
Regards,
Sherif
