In the case of directly controlled two-way solenoid valves, the position of the closing element on the seat is changed directly by the force of the magnetic field of the electromagnet, while the closing element is directly the core of the electromagnet. The basic position of the valve, to which the closing element of the valve is reset after canceling the electrical signal, is provided by a spring in the closing element - the core, moving in the cavity of the electromagnet line, with the help of medium pressure. Direct actuation is only used for small clearance valves up to 10mm seat diameter, as larger clearances would require large high power spools.
