What is Critical Flow Factor (Cf)?

Critical Flow Factor (Cf) is a coefficient that defines how pressure will recover after it drops to its lowest point (the vena contracta*) inside the control valve.  Each valve has one Critical Flow Factor, and this number doesn’t change due to percentage open, like the Flow Coefficient (Cv) does. Cf is a factor that is needed in

Quick Tips Video | How to Weight a Float Ball

In this video, Jerry from Kimray and Tim from Superior Fabrication (SFI) discuss utilizing a float ball with a float arm inside a vessel along with a mechanical dump valve. In a production process the oil floating on top of the water has an interface line. For this float to be able to sense the water
