派克换向阀，PARKER电磁换向阀，派克D1VW系列电磁换向阀是一种3油腔电磁控制的三位四通或二位四通方向控制阀，通过旋入式衔于铁管湿式电磁铁直接控制。线圈能够根据不同的输入电压进行调换，但是交流和直流之间不能更换。

Parker电磁换向阀的品种繁多，按其工作位置数和通路数的多少可分为二位三通、二位四通、三位四通等；按其复位和定位形式可分为弹簧复位式、钢球定位式、无复位弹簧式；按其阀体与电磁铁的连接形式可分为法兰连接和螺纹连接；按其所配电磁铁的结构形式可分为干式和湿式，每一类又有交流、直流、本整等形式，而且所需电源电压又有好多种，因而在其结构上存在很多差别。

派克电磁换向阀D1VW020系列是用电磁铁的吸力来推动阀芯运动以变换流体流动方向的控制阀，简称电磁阀，通常有滑阀和球阀两种结构，通常所说的电磁换向阀为滑阀结构，称球状或锥状阀芯的电磁换向阀为电磁换向座阀，也称电磁球阀。

美国Parker派克电磁换向阀的性能：

换向性能：在规定的工作条件下，电磁阀通电后能否可靠地换向，断电后能否可靠地复位。
压力损失：电磁换向阀的压力损失由液流流过电磁换向阀的阀口时产生的流动损失和节流损失组成。

内泄露量：电磁换向阀的内泄露量是指在规定的工作条件下，处于各个不同工作位置时，从高压腔到低压腔的泄露量。
换向和复位时间：从电磁铁通电到阀芯换向终止所需要的时间，复位时间是指从电磁断电到阀芯回复到初始位置所需要的时间。

换向频率：在单位时间内所允许的zui大换向次数
使用寿命：电磁阀使用到主要零部件损坏，不能进行正常的换向和复位动作，或者使用到其主要性能指标明显恶化超过了规定指标所经历的换向次数。Parker电磁换向阀，派克四通方向阀，派克D1VW系列电磁换向阀，Parker电磁方向控制阀，Parker换向阀
