Critical flow factor air control valve
Critical Flow Factor, often referred to as “Cf” is a coefficient that defines how pressure will recover after it drops to its lowest point … See more Cf is a factor needed in order to calculate Flow Coefficient (Cv) or Flow Rate for valve sizing purposes. You can find the Cf for each Kimray … See more Below is an illustration of how Cf is determined. First, fluid or gas (shown here in light blue) enters a control valve. This results in the pressure droping until it reaches the vena … See more Web8.1.1 Flow Control Verification Test. Prior to initial field deployment and at least every six months, you must verify that the sampling device’s ability to control flow to the canister is acceptable. Assemble an evacuated canister with the sampling device including filter connected to a certified flow meter.
