Abstract
A method of assembling an electromagnetically actuatable disc-type valve permits separate assembly of the hydraulic components from the electrical components. The constant shape of the exterior surface of the core member enables the hydraulic sub-assembly to be assembled separately from the electrical sub-assembly and thereafter inserted into the electrical sub-assembly. The valve's plastic covering is applied to the electrical components separately and before the hydraulic components are assembled with the electrical components. In this way, the heat involved does not affect the calibration of the hydraulic components. A bushing is disposed to lock the two sub-assemblies at the desired relative orientation. The fluid filter is inserted into the valve before the calibration slide is inserted into the valve. The valve is flow checked before setting the tension on the armature of the valve.
