电磁阀里有密闭的腔，在不同位置开有通孔，每个孔连接不同的油管，腔中间是活塞，两面是两块电磁铁，哪面的磁铁线圈通电阀体就会被吸引到哪边，通过控制阀体的移动来开启或关闭不同的排油孔，而进油孔是常开的，液压油就会进入不同的排油管，然后通过油的压力来推动油缸的活塞，活塞又带动活塞杆，活塞杆带动机械装置。这样通过控制电磁铁的电流通断就控制了机械运动 派克电磁换向阀 D91VW001C1NJW3F91 D91VW001C2NJW91 D91VW001C2NJWTI6N91 D91VW001C4NUWI6N91 D91VW001C5NJWTI6N91 D91VW001E2NJW91 D91VW001K1NJWI1N91 D91VW001K1NJWI4N91 D91VW001K1NJWTI4N91 D91VW003C1NJW91 D91VW004C2NJW91 D91VW004C4VTW91 D91VW004C5NJW91 D91VW009C1NJWTI6N91 D91VW009C2NJW91 D91VW009C5NJW91 D91VW012C2NJWW91 D91VW015C4NJW3A91 D91VW020B2NJW1R91 D91VW020D1NUW91 D91VW020H1NJW91 D91VW021C2NJWT91 D91VW021K5NJWTI4N91 D91VW026H2NJWT91 D91VW043E2NJWTI5N91 D91VW054C1VJW91 D91VW054C4VJW91 D91VW10C5NJP D91VW11C1NJP D91VW11C1NJP89 D91VW11C4NJP D91VW11C4NJW89 D91VW15C1NJW D91VW15C4NJP D91VW15C4NJP60 D91VW16C2NJW D91VW16K2NJW D91VW1C1NJC D91VW1C1NJP D91VW1C1NJW D91VW1C2NJP D91VW1C2NJW D91VW1C2NJW27 D91VW1C2NJW7 D91VW1C2NJW89 D91VW1C4NJP D91VW1C4NJP88 D91VW1C4NJP89 D91VW1C4NJW D91VW1C4NJW89 D91VW1C4VJW D91VW1C5NJP D91VW1C5NJW88 D91VW1E2NJW D91VW1K4NJW D91VW20B1NJW D91VW20B2NJW D91VW20D1NJW60 D91VW20D2NJW D91VW20D2NJW60 D91VW20D4NJP D91VW20H2NJW D91VW20H2VJW D91VW20H4NJP D91VW20H5NJW D91VW21C2NJP D91VW21C4NJW D91VW21C5NJC5 D91VW21C5NJW D91VW2C2NJW D91VW2C5NJP D91VW30B2NJW D91VW30B2VJW D91VW30B5NJW D91VW30H2NJW D91VW30H2VJP D91VW34C5NJW D91VW3C1NJW789 D91VW3C1VJW D91VW3C2NJP D91VW3C4NJP D91VW3C4NJW D91VW3C4NJW7 D91VW3C4NJW789 D91VW3C4NJW89 D91VW43H2NJW66 D91VW43H5NJW66 D91VW4C1NJP D91VW4C1NJW D91VW4C1NJW66 D91VW4C1NJW89 D91VW4C2NJW D91VW4C4NJEE75 D91VW4C4NJEE775 D91VW4C4NJP D91VW4C4NJP7 D91VW4C4NJW D91VW4C4NJW55 D91VW4C4NPEE75 D91VW4C4VJW
