亚德客先导式电磁阀：
特点：流体压力范围上限较高，可任意安装（需定制）但必须满足流体压差条件。
原理：通电时，电磁力把先导孔打开，上腔室压力迅速下降，在关闭件周围形成上低下高的压差，流体压力推动关闭件向上移动，阀门打开；断电时，弹簧力把先导孔关闭，入口压力通过旁通孔迅速腔室在关阀件周围形成下低上高的压差，流体压力推动关闭件向下移动，关闭阀门。
电磁阀从阀结构和材料上的不同与原理上的区别，分为六个分支小类：直动膜片结构、分步直动膜片结构、先导膜片结构、直动活塞结构、分步直动活塞结构、先导活塞结构。
AirTac pilot solenoid valve:
Features: the upper limit of the fluid pressure range is higher, can be arbitrarily installed (to be customized) but must meet the conditions of fluid pressure difference.
Principle: power, the electromagnetic force to open the pilot hole, the chamber pressure to drop rapidly in close formation around the lower parts of high pressure, fluid pressure to promote the closure of parts moving up, the valve open; power, the spring force of the pilot hole closed, entrance pressure chamber through the bypass hole quickly formed under low. The high pressure around the valve off, fluid pressure to promote the closure of parts moving down, close the valve.
Solenoid valve from different principle and valve structure and materials on, divided into six branch categories: diaphragm structure, step by step direct acting diaphragm structure, pilot diaphragm structure, direct acting piston structure, direct acting piston structure step by step, the pilot piston direct drive structure.
亚德客直动式电磁阀：
特点：在真空、负压、零压时能正常工作，但通径一般不超过25mm。
原理：通电时，电磁线圈产生电磁力把关闭件从阀座上提起，阀门打开；断电时，电磁力消失，弹簧把关闭件压在阀座上，阀门关闭。
AirTac direct acting solenoid valve:
Features: in a vacuum, negative pressure, zero pressure can work normally, but generally not more than 25mm.
Principle: when the power is on, the electromagnetic force of the electromagnetic force to shut off the valve seat, the valve open; power, the electromagnetic force disappears, the spring to close the pressure on the seat, the valve closed.
