Dear All How do i parameterize the 2 way and 3 way directional valve with given manufacturer data sheet current vs flow rate?

The directional valve blocks have a Model Parameterization option in their dialogs. Two of those values let you enter your own data from, e.g., a datasheet.
From the documentation:
  • By area vs. opening table — Provide tabulated data of valve openings and corresponding valve passage areas. The passage area is determined by one-dimensional table lookup. You have a choice of two interpolation methods and two extrapolation methods.
  • By pressure-flow characteristic — Provide tabulated data of valve openings, pressure differentials, and corresponding flow rates. The flow rate is determined by two-dimensional table lookup. You have a choice of two interpolation methods and two extrapolation methods.

Dear Castro
But in my data sheet valve displacement is not given. it has only current vs flow rate. so how does i do parameterize the valve.

Current? As in electric current, probably for a valve solenoid or something?
Is that then current vs. flow rate for a specific pressure? Because if so, you can probably back out the valve area as a function of input current...
