WebThe flow coefficient for a control valve which in full open position passes 25 gallons per minute of water with a one pound per square inch pressure drop can be calculated as: Cv = (25 gpm) (1 / (1 psi))1/2 = 25 Flow Coefficient - Cv - for Saturated Steam WebA control valve is a power operated device capable of modulating flow at varying degrees between minimal flow and full capacity in response to a signal from the controlling system. Control valves may be broadly classified by their function as “on-off” type or “flow regulating” type.
