TONHI油泵,TONHI电磁阀是阀门的一种，使用电磁线圈驱动。TONHI油泵,TONHI电磁阀的工作原理如下：通过对电磁线圈通电／断电控制管路的开启／关闭或改变流体（一般是压缩空气或者液体）流向（电磁开关阀）。改变通过电磁线圈电压／电流（一般为电流譬如4-20mA的直流电流）等参数控制管路中流体流量或流体压力（电磁调节阀）。

TONHI油泵,TONHI电磁阀产品适用介质受限。电磁阀通常只有开关两种状态，阀芯只能处于两个极限位置，不能连续调节，（力图突破的新构思不少，但还都处于试验试用阶段）所以调节精度还受到一定限制。电磁阀对介质洁净度有较高要求，含颗粒状的介质不能适用，如属杂质须先滤去。另外，粘稠状介质不能适用，而且，特定的产品适用的介质粘度范围相对较窄。型号多样，用途广泛。电磁阀虽有先天不足，优点仍十分突出，所以就设计成多种多样的产品，满足各种不同的需求，用途极为广泛。电磁阀技术的进步也都是围绕着如何克服先天不足，如何更好地发挥固有优势而展开。
