Selected Cg (Flow Coefficiant) Maximum and Minimum
Selected Cg (Flow Coefficiant) Maximum and Minimum
(OP)
Hello Everyone,
Im currently working on sizing some control valves. They are anti-surge valves. Im trying get my head around the flow coefficient and what it exactly means. When valves are being sized you are normally given values of CgMin CgMax. I also see a Selected Cg value.
What do these three coefficients tell me?
Thanks in Advanced

The minimum valve flowing requirement of the application
The maximum valve flowing requirement of the application
The selected Cg is the Cg of the valve you have selected.
Anti-surge valves are tricky. They are usually oversized by factors of 1.5 to 2. You may want to look on the internet for guidence.
