Design
The proportional valve MPYE－5－1／8 is assembled on a base which incorporates the quick release detent system（mounting alternative“A”）suitable for profile－plate mounting.The valve is equipped with LCU push－in fittings and two silencers.The major internal components of a pro⁃portional directional control valve are：
A pneumatic 5／3－way valve of spool design，closed in its mid－position（1）
A plunger－armature drive（2）to position the valve spool
A sensor（3）to measure the valve spool position
Integrated valve electronics（4）to control the valve spool po⁃sition.

设计
二位五通双电磁换向阀MPYE－5－1／8安装在功能板上，通过快速释放手柄的扣紧系统安装在型材工作台面上（安装方案“A”）。该阀配备了LCU快插式接头及两个消声器。
比例方向控制阀的内部主要组件是：
气动三位五通阀，中位封闭（1）；
柱塞电枢驱动器（2），用于定位阀芯；
传感器（3），用于测量阀芯位置；
集成阀电子块（4），用于控制阀芯位置。
Function
The proportional directional control valve converts an ana⁃logue electrical input signal into appropriate cross－section o⁃penings to the outputs.At half the nominal voltage，i.e.5 V，the valve assumes its pneumatic mid－position，in which all control edges are closed，so that no air apart from minimal leakage passes through the valve.At 0 and 10 V respective⁃ly，the valve assumes one of its end positions，with maximum opening cross－section.
A plunger－armature drive acting directly on the pneumatic spool valve acts as an electromechanical transducer.An inte⁃grated electronic control for the valve－spool travel（subordi⁃nate position control loop）allows good static and dynamic characteristics to be obtained，which are reflected in the low hysteresis（below 0.3%），short actuating time（typically 5 ms）and high maximum frequency（approx 100 Hz）.The valve is thus particularly suitable for use as a final control el⁃ement in conjunction with a higher－level position controller for the positioning of a pneumatic cylinder.
If the valve spool jams，for example due to dirt，the valve cover cap（6）can be removed and the valve spool freed by hand.
Electrical connection
The pin assignment of the housing socket and the colourcoding for the plugs of the cable are shown in the following table.
功能
比例方向控制阀把模拟量电气输入信号转换成适当的横截面开口输出。在额定电压的一半，即5 V时，阀门设定在其气动中间位置，关闭所有控制边缘，因此，除了最小泄漏外没有空气通过阀门。在0 V和10 V，阀门处于终点位置，设定为最大开放的横截面。
柱塞衔铁驱动器直接作用于气动阀完成电与机的转换。集成电子控制阀阀芯行程（从属地位控制回路）保证了良好的静态和动态特性的获得，这反映在滞后低（低于0.3%）、启动时间短（一般为5 ms）和高的最大频率（约100 Hz）。因此，特别适合作为最终控制元件在一个气缸的定位与更高级别的位置控制器一起使用的阀门。
如果阀芯堵塞（例如，由于污垢堵塞），则可以移除阀盖（6），手动释放阀芯。

六、安装技术
实际操作过程中，元器件安装在Festo Didactic培训系统的铝合金底板上。铝合金底板共有14条间距50 mm的T型平行凹槽。
铝合金底板主要用于安装下列A～D四种不同类型的元器件：
A：卡座式安装系统，固定时无须使用其他元件。元件固定在卡座上，夹紧卡座两侧的手柄就可以在铝合金底板的T型槽内移动卡座，松开手柄则固定卡座。用于轻质、无负载的元器件。
B：旋转式安装系统，固定时无须使用其他元件。带有锁紧圆盘，通过旋紧元件底座上的螺帽和底座下面的T型螺钉来垂直或水平固定元件。用于较重、带负载的元器件。
C：螺钉固定式安装系统，固定时需使用其他元件。通过内六角螺钉和T型螺母垂直或水平固定元件。用于重型、带较重负载的元件或无须经常取下的元器件。
D：快插式安装系统，固定时需要接头。元件通过定位栓固定，可以沿着凹槽方向移动。用于轻质、无负载的元件。
电信号开关单元、电信号指示单元和继电器也可以安装在ER电器安装支架上。
使用A型卡座式安装系统时，卡座中有一滑片与铝合金底板的凹槽咬合，滑片通过弹簧拉紧。压下卡座的蓝色手柄，滑片缩回，可以在铝合金底板的凹槽中取出或安装元件。元器件在凹槽内移动并通过凹槽对齐。
使用B型旋转式安装系统时，通过旋紧元件底座上的蓝色螺帽和底座下面的T型螺钉固定元件。锁紧圆盘可以以90°的角度旋转来固定元器件，因此可以与凹槽平行或垂直安装元件。
当锁紧圆盘位于需要的位置时，元件放置在铝合金底板上，顺时针旋转锁紧螺帽，T型螺钉在铝合金底板凹槽中以90°旋转，继续旋转螺帽，则将元件固定。
C型螺钉固定式安装系统用于安装重型元件，或一旦固定就很少移动的元件。此时，使用内六角螺钉和T型螺母固定元件。
使用D型快插式安装系统时，ER单元可以插入到带定位栓的实验板上，并通过套管接头与铝合金实验板相连，每个定位栓都带有一个黑色塑料接头。T型槽上每隔50 mm要有一个接头，将接头旋转90°即可固定，然后ER单元的定位栓便可插入到接头的穿孔中。
