原裝德國PILZ皮爾茲繼電器工作原理：德國PILZ繼電器是用來控制流體的自動化基礎元件，屬于執行器；并不限于液壓，氣動。德國PILZ繼電器用于控制液壓流動方向，工廠的機械裝置一般都由液壓鋼控制，所以就會用到德國PILZ繼電器。 德國PILZ皮爾茲繼電器工作原理，德國PILZ繼電器里有密閉的腔，在的不同位置開有通孔，每個孔都通向不同的油管，腔中間是閥，兩面是兩塊電磁鐵，哪面的磁鐵線圈通電閥體就會被吸引到哪邊，通過控制閥體的移動來檔住或漏出不同的排油的孔，而進油孔是常開的，液壓油就會進入不同的排油管，然后通過油的壓力來推動油剛的活塞，活塞又帶動活塞桿，活塞竿帶動機械裝置動。這樣通過控制電磁鐵的電流就控制了機械運動。上面說得是德國PILZ繼電器的普通原理實際上，根據流過介質的溫度，壓力等情況，比如管道有壓力和自流狀態無壓力。德國PILZ繼電器的工作原理是不同的。比如在自流狀態下需要零壓啟動的，就是通電后，線圈整個把閘體吸起來。而有壓力狀態的德國PILZ繼電器，則是線圈通電后吸出插在閘體上的一個銷子，用流體自身的壓力把閘體頂起來。這兩種方式的不同之處是，自流狀態的德國PILZ繼電器，因為線圈要吸起整個閘體，所以體積較大而帶壓狀態的德國PILZ繼電器，只需要吸起銷子，所以體積可以做的比較小。
