Solenoid valve comprising an electromagnet subassembly and a pneumatic switching assembly with valve plug mechanically associated with the electromagnet subassembly. The pneumatic switching subassembly is composed of a body enclosing th valve plug trapped between two sealing seatings facing each other. The movement of the valve plug is controlled firstly by a spring located in the 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 assembly when the electromagnet is energized. The solenoid valve comprises 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 the frustum of a sphere. The pneumatic switching subassembly comprises four cylindrical cavities at its assembly plane with the electromagnet subassembly, designed to hold the pins of the electromagnet subassembly.
