美国ASCO世格G551A002MS双控电磁阀的设计原理一是为了节能减耗,二是为了让线圈能够长期稳定的工作。双控电磁阀有两个线圈,一侧通电时阀门换向,断电以后也不会回位(无弹簧)保持畅通状态。 The design principle of the American ASCO G551A002MS dual control solenoid valve is to save energy and reduce consumption, and second, to allow the coil to work stably for a long time. The dual-control solenoid valve has two coils, and the valve reverses when energized on one side, and will not return to b (without spring) to maintain a smooth state after power off.
