Calibration process for the mobile spring of a solenoid valve

A solenoid valve has an electromagnet subassembly and a pneumatic switching subassembly. A valve plug is mechanically associated with the electromagnet subassembly, the pneumatic switching subassembly includes a body enclosing the valve plug trapped between two sealing seating facing each other. The movement of the valve plug is controlled firstly by a spring located in a mobile core of the electromagnet subassembly through a pusher, and secondly by a means that forces the valve plug into contact on the upper seating of the pneumatic switching subassembly when the electromagnet is energized. The electromagnetic subassembly has four cylindrical pins at its assembly plane on the pneumatic switching subassembly, each cylindrical pin being provided with a transverse cavity formed on the generating line of the pin and terminating with a frustum of a sphere. The pneumatic switching subassembly includes four cylindrical cavities as its assembly plane with the electromagnet subassembly.
