It's a Cameron CC40 SSRC, Plug and Cage, Linear with Cv of 300.
How about an analogy. I'm flowing 5000 m3/day of water through an orifice of 1.5". Say the U/S pressure is 5000 kPa (all numbers are abitrary). If I decrease the orifice size to 0.5" but want the same flow, how do I get it? I bump...
I understand where you are coming from. However, the valve is currently doing 82% of its rated capacity but only 35% open. According to its curve, at 35%, the Cv is 110, about 30% of Cv when full open.
As far as size goes it doesn't matter. However I agree with your previous comment of how...
It's not the pressure drop I'm concerned about. It's the velocity through the valve that may give problems.
As stated earlier, the upstream operating pressure of the valve is spec'd at 8600 kPa (although MAWP is 10000 psi). However, the current U/S pressure is 11000 kPa resulting in a valve...
I've been tasked with determining whether our subsea choke valves are at risk due to erosion. The design data is:
flow of water = 4000 m3/day (SG = 0.96)
flow of oil = 2000 m3/day (SG = 0.87)
flow of NG = 1,800,000 Sm3/day (SG = 0.67)
Calculated Cv = 300
T1 = 95 deg C
dP = 610 kPa
The...
