The main advantage:

Interface: PT1/4: AC220V / 200V; voltage: AC110V/run at 100V, DC24V
< > 1 27mm width of ontology, effective 12mm2 area. In diameter for 1/4,
< 2 > new shape, only lower oil seal system dynamic can slide,
< > 3 special grease, make interior without oil supply, do not affect its life,
< > 4, low power consumption, you 2W DC24V (.).
< 5 > high response, high reliability, long life, life for one time.
< > the highest use frequency for 6 240 times/minute,
< > 7 for use, below the 63 cylinder,
