5. Working principle 5.1 working principle This valve is a pilot-operated solenoid valve. which has two movable iron cores, and there are rubber pads at the lower ends of the iron cores. When the upper coil is energized, the upper iron core is sucked up and a small flow channel is opened. When the power is lost, the upper iron core is pressed down by the spring force to close the valve. When the upper coil is energized first to lift the upper iron core, and then the lower coil is energized (or the upper and lower coils are energized at the same time), the lower iron core is lifted up to open...

6. Installation and Maintenance 6.1 The medium flow direction in the solenoid valve should be consistent with the direction of the arrow on the valve body, and the power supply voltage and medium pressure should be consistent with those marked on the nameplate. 6.2 The solenoid valve should be connected horizontally and installed on the horizontal pipeline. 6.3 The introduction device of the solenoid valve adopts a permanent four-core cable. The free end of the cable should be properly processed and connected to the corresponding explosion-proof box. The minimum outer diameter of the applicable...
