A solenoid valve (300,400) with direct command normally closed or normally open, adapted to work with both direct and alternate current, comprising: a main body, provided with an inlet channel for a fluid, an outlet channel for discharging of said fluid, an orifice between said inlet and outlet; a shutter of said orifice; a movable elongated core having a first end connected to said shutter; a further elongated balancing rod (301,401), having at least one calibrated passage area (302, 402), a first end connected to said shutter and a second end moving in a passage formed in said main body and having the axis parallel to the axis of said orifice; and a central discharge channel made in the movable core and the balancing rod (301, 401) and in fluid communication with the outlet channel; said outlet channel being substantially angled with respect to said inlet channel, characterized in that said solenoid valve further comprises a gasket disposed directly between a sleeve and the movable core, to increase the dimensions of orifice and consequently increase the flow rate of the valve, said orifice together with said gasket being adapted to maintain the pressure balance in opening said valve (300,400) and limit fluid losses, said gasket sealing said movable core against leaks, keeping balanced the pressures acting on said movable core relative to those acting on the balancing rod (301, 401) in the closure stage, and in that the flow passes from the inlet channel, through a system consisting of the balancing rod including the calibrated passage area in the form of calibrated holes, into the outlet channel, the calibrated holes being arranged in a direction substantially orthogonal to the development line of the inlet channel, or through the system consisting of said balancing rod not comprising a plurality of holes, but for the flow passage the bottom diameter of said balancing rod is smaller than the diameter of a seat of said balancing rod. a main body, provided with an inlet channel for a fluid, an outlet channel for discharging of said fluid, an orifice between said inlet and outlet; a shutter of said orifice; a movable elongated core having a first end connected to said shutter; a further elongated balancing rod (301,401), having at least one calibrated passage area (302, 402), a first end connected to said shutter and a second end moving in a passage formed in said main body and having the axis parallel to the axis of said orifice; and a central discharge channel made in the movable core and the balancing rod (301, 401) and in fluid communication with the outlet channel; said outlet channel being substantially angled with respect to said inlet channel, characterized in that said solenoid valve further comprises a gasket disposed directly between a sleeve and the movable core, to increase the dimensions of orifice and consequently increase the flow rate of the valve, said orifice together with said gasket being adapted to maintain the pressure balance in opening said valve (300,400) and limit fluid losses, said gasket sealing said movable core against leaks, keeping balanced the pressures acting on said movable core relative to those acting on the balancing rod (301, 401) in the closure stage, and in that the flow passes from the inlet channel, through a system consisting of the balancing rod including the calibrated passage area in the form of calibrated holes, into the outlet channel, the calibrated holes being arranged in a direction substantially orthogonal to the development line of the inlet channel, or through the system consisting of said balancing rod not comprising a plurality of holes, but for the flow passage the bottom diameter of said balancing rod is smaller than the diameter of a seat of said balancing rod.
