The working principle of distributed direct-acting solenoid valve: it is a combination of direct-acting and forerunner. When there is no pressure difference between the inlet and outlet of the direct moving solenoid valve, the electromagnetic force directly turns off the pilot small valve and the main valve, thus opening the valve. When the inlet and outlet to start the differential pressure, the electromagnetic force pilot valve work, the main valve chamber pressure rise, the upper practical standard text pressure drop, the main valve is pushed up the differential pressure. In the case of power failure, electromagnetic force pilot valve through the spring force or medium pressure to push down the closure, thus closing the valve. Solenoid valve operation characteristics: can be zero pressure difference or vacuum high pressure operation, but the power is large, the need for horizontal installation.

The working principle of the conductive solenoid valve: when energized, the electromagnetic force opens the conductive hole, so that the pressure of the upper chamber falls rapidly, forming a high and low pressure difference around the closed parts, and the fluid pressure pushes the closed parts upward, and the valve opens; When the power is off, the spring force closes the conductive hole, so that the inlet pressure rapidly forms a high and low pressure difference through the bypass hole, and the fluid pressure pushes the closing part down to close the valve. Operation features: high hydraulic range upper limit, optional installation (customized), but must meet the conditions of poor hydraulic.
