派克換向閥，PARKER電磁換向閥，派克D1VW系列電磁換向閥是一種3油腔電磁控制的三位四通或二位四通方向控制閥，通過旋入式銜于鐵管濕式電磁鐵直接控制。線圈能夠根據(jù)不同的輸入電壓進(jìn)行調(diào)換，但是交流和直流之間不能更換。 Parker電磁換向閥的品種繁多，按其工作位置數(shù)和通路數(shù)的多少可分為二位三通、二位四通、三位四通等；按其復(fù)位和定位形式可分為彈簧復(fù)位式、鋼球定位式、無復(fù)位彈簧式；按其閥體與電磁鐵的連接形式可分為法蘭連接和螺紋連接；按其所配電磁鐵的結(jié)構(gòu)形式可分為干式和濕式，每一類又有交流、直流、本整等形式，而且所需電源電壓又有好多種，因而在其結(jié)構(gòu)上存在很多差別。 派克電磁換向閥D1VW020系列是用電磁鐵的吸力來推動(dòng)閥芯運(yùn)動(dòng)以變換流體流動(dòng)方向的控制閥，簡稱電磁閥，通常有滑閥和球閥兩種結(jié)構(gòu)，通常所說的電磁換向閥為滑閥結(jié)構(gòu)，稱球狀或錐狀閥芯的電磁換向閥為電磁換向座閥，也稱電磁球閥。

美國Parker派克電磁換向閥的性能： 換向性能：在規(guī)定的工作條件下，電磁閥通電后能否可靠地?fù)Q向，斷電后能否可靠地復(fù)位。
壓力損失：電磁換向閥的壓力損失由液流流過電磁換向閥的閥口時(shí)產(chǎn)生的流動(dòng)損失和節(jié)流損失組成。 內(nèi)泄露量：電磁換向閥的內(nèi)泄露量是指在規(guī)定的工作條件下，處于各個(gè)不同工作位置時(shí)，從高壓腔到低壓腔的泄露量。
換向和復(fù)位時(shí)間：從電磁鐵通電到閥芯換向終止所需要的時(shí)間，復(fù)位時(shí)間是指從電磁斷電到閥芯回復(fù)到初始位置所需要的時(shí)間。 換向頻率：在單位時(shí)間內(nèi)所允許的zui大換向次數(shù)
使用壽命：電磁閥使用到主要零部件損壞，不能進(jìn)行正常的換向和復(fù)位動(dòng)作，或者使用到其主要性能指標(biāo)明顯惡化超過了規(guī)定指標(biāo)所經(jīng)歷的換向次數(shù)。Parker電磁換向閥，派克四通方向閥，派克D1VW系列電磁換向閥，Parker電磁方向控制閥，Parker換向閥 |
