Abstract: Process for calibration of the mobile core spring of a solenoid valve comprising an electromagnet subassembly associated with a pneumatic switching subassembly with a valve plug, the valve plug being moved in the body of the pneumatic switching subassembly firstly by a spring located in the mobile core of the electromagnet subassembly through a pusher, and secondly by a spring located under the valve plug and bearing around the lower seating of the pneumatic switching subassembly, this process comprising the following steps: a force sensor is put into position, either at a predetermined distance from the upper face of the mobile core, this distance being equivalent to the actual travel distance of the mobile core, or directly in contact with the face of the core when it is required to adjust the spring based on its force after the travel distance (core in contact on the yoke); the spring is installed in a reaming providing for this purpose in the axis of the mobile core: an elastic split pin is put into po

Abstract: 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.
