进口先导式电磁阀

    德国LIT进口先导式电磁阀有几点特点（1）动作快，功率小，外形轻巧。电磁阀响应时间可以短至几个毫秒， 即使是先导式电磁阀也可以控制在几十毫秒 内。由于自成回路，比之其它自控阀反应更灵敏。设计得当的电磁阀线圈功率消 耗很低，属节能产品；还可做到只需触发动作，自动保持阀位，平时一点也不耗电。（2）调节精度受限，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， （德国力特试图突破，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。（3）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。

Germany LIT imports pilot solenoid valve There are several characteristics of （1） the action is fast and small power, lightweight form factor. Solenoid valve response time can be as short as a few milliseconds, even if it is a pilot-type solenoid valve can also be controlled to within tens of milliseconds. Self-loops, other than the automatic control valve response is more sensitive. Properly designed solenoid valve coil power consumption is very low, an energy-saving products; trigger actions can also be done simply, and automatically maintain valve position, usually is not consumable. （2） to adjust the accuracy is limited, restricted Applicable medium. The solenoid valve is usually only switch the two states, the spool only at the two extreme positions, can not be adjusted continuously, （German special forces tried to break through, but also in the experimental trial stage） regulation accuracy is also subject to certain restrictions. Solenoid valve with higher requirements for media cleanliness, containing granular media can not be applied, the case must first filter out impurities. In addition, the viscous medium is not applicable, and particular product is suitable for medium viscosity range is relatively narrow. （3） Model diverse, wide range of uses. Although the solenoid valve deficiencies, the advantages still very prominent, so a wide variety of products designed to meet the various needs, extremely versatile. Solenoid valve technology advances are also around how to overcome the inherent weaknesses, and how to better play to the inherent advantages and expand.
