      工作原理:
      常閉:當(dāng)線圈通電時(shí),先導(dǎo)閥芯吸合,先導(dǎo)孔打開,閥上腔卸壓,活塞靠下腔介質(zhì)壓力推動(dòng),電磁閥打開;當(dāng)線圈斷電時(shí),先導(dǎo)閥芯靠彈簧復(fù)位,先導(dǎo)孔關(guān)閉,閥上腔由活塞節(jié)流孔增壓和復(fù)位彈簧的推力,電磁閥關(guān)閉。

      How it works: 
      NC: When the coil is energized, the pilot spool pull the pilot hole to open, pressure relief valve on the chamber, the piston on the lower chamber medium pressure to promote, the electromagnetic valve is opened; When the coil power, the pilot valve by the spring return, pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the electromagnetic valve is closed. 
      Normally Open: When the coil is energized, the pilot hole closed, the valve chamber and pressurized by the piston return spring throttle thrust, the electromagnetic valve is closed. When the coil power, the pilot valve by the spring return, pilot hole open, pressure relief valve on the chamber, medium pressure piston push the lower chamber, the electromagnetic valve is opened.
