Cartridge valves fit into cavities, for MDTools we have 2 type of cavities: standard and “sun cavities”. Standard means a cavity with C’Bore, Sun Cavities take origin to Sun Hydraulics valves, they mate with a Locating Shoulder that’s inside the cavity. Below we see 2 examples of cavities taken from MDTools Library Manager.
Standard Cavity, mating plane = SpotFace
Sun Cavity, mating plane = Locating Shoulder (LS)
Cartridge valve rules are set through MDTools Set Constraints dialog. For a cartridge valve we need 3 constraints: top face, bottom face, axis.
Each of these geometries must be set directly in the valve 3d model
MDTools Set Constraints command is available in both assembly and part environment for SolidWorks and Autodesk Inventor.
Top face is always required, it is not relevant when the cartridge will not have any additional item assembled on top (i.e. a coil, a nut).
Coils, nut… will require same constraints to be assembled automatically by MDTools
Below example of Bottom Face / Top Face for Cartridge, Coil and Nut for a Solenoid Valve assembly.
Video showing how to set Constraints and create assembly with MDTools on SolidWorks. MDTools on Autodesk Inventor behaves very similarly so each item described is applicable. If you need more info feel free to contact us
