Cv in pneumatics
WebThe valve flow coefficient (C v) is a convenient way to represent flow capacity of a valve across a range of fluids and process parameters. The C v calculator will calculate either C v or flow using the supplied additional parameters of fluid, inlet and outlet pressure, and fluid temperature. The calculations can be performed for either liquid ... WebParker 2-Way Normally Closed, 1/2" NPT Solenoid Valves provide operating pressures up to 300 PSI and flow factors up to 4.4 CV's. They offer multiple body materials, mounting positions and Class F or H or NEMA 4X, 7 or 9 coils for all flow applications.
