1. Direct acting solenoid valve Principle: When energized, the solenoid coil generates electromagnetic force to lift the closing piece from the valve seat and open the valve; When the power is cut off, the electromagnetic force disappears, the spring presses the closing element on the valve seat, and the valve closes. Features: It can work normally under vacuum, negative pressure and zero pressure, but the diameter generally does not exceed 25mm. Working principle, The piston drives the piston rod, which drives the mechanical device. In this way, the mechanical movement is controlled by controlling the current of the electromagnet. 2. Step direct acting solenoid valve Working principle: it is a combination of direct action and pilot type. When there is no pressure difference between the inlet and outlet, the electromagnetic force will directly lift the small pilot valve and the main valve closure piece upward in turn and open the valve after power on. When the inlet and outlet reach the starting differential pressure, the electromagnetic force will pilot the small valve, and the pressure in the lower chamber of the main valve will rise and the pressure in the upper chamber will drop, so that the main valve can be pushed upward by using the differential pressure; When the power is cut off, the pilot valve uses spring force or medium pressure to push the closing piece to move downward to close the valve. Features: It can also operate under zero differential pressure, vacuum and high pressure, but the power is large, so it must be installed horizontally.
