DANA Cartridge valves and logic elements
The mounting surface must feature surface quality specified in data sheet of the valve: for example for Cetop valves generally is required Ra ≤ 1.6µm and flatness ≤ 0.03 mm over 100 mm length. Normally in cartridge valve for sealing diameters of the cavities, is required roughness Ra ≤ 1.6µm. The surfaces and openings in the assembly plate must be free from impurity or dirt. Make sure the O-Rings fit correctly in their seats. Fixing screws must comply with the dimensions and the strength class specified in the data sheet and must be tightened at the specified tightening torque. Complete the electrical wiring. For circuit examples and pin assignments, see the relevant datasheet.
