Constr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(To order, add prefix “EF” or, for Explosionproof Stainless Steel trim

and hub on Brass-Bodied valves, add “EV” to catalog number.)

See Optional Features Section for other available options.

Standard的移动来开启或关闭不同的排油孔，而进油孔是常开的

Refer to Engineering Section for details.

Approvals:

CSA certified. UL listed as General Purpose Valve. Meets

applicable CE directives.

Refer to Engineering Section for details.

Important:

A Minimum Operating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。[1] uction
