NACHI's solenoid valves for automobiles are well-recognized for their compact design, high responsiveness, and reliable performance. They are mainly applied in key automotive systems like automatic transmissions and new energy vehicle power control modules. Below is a detailed overview covering core aspects such as key types, prominent features, main applications and working principles:

NACHI automotive solenoid valves are mainly divided into three types according to their working principles to adapt to different working conditions. The direct-acting type uses electromagnetic force to directly drive the valve core to move against spring force to open or close the valve, and can work normally under vacuum and negative pressure conditions. The step-by-step direct-acting type combines the principles of direct-acting and pilot-operated types. It can operate stably under zero pressure difference and high-pressure conditions. The pilot-operated type opens the pilot hole through electromagnetic force to form a pressure difference around the valve core, so as to push the main valve to open. It has a high upper limit of fluid pressure range and can be installed flexibly.
