電磁鐵等各處以新設(shè)計(jì)思想開(kāi)發(fā)的劃時(shí)代的高壓、大流量電磁閥。采用濕式電磁鐵，壽命長(zhǎng)，噪聲低，無(wú)外部泄漏。
- 適應(yīng)多樣化需要的類型
  具備有兩種類型，選用zui適用的閥。
  ·標(biāo)準(zhǔn)型，高壓（31.5MPa），大流量（120L/min）。
  ·無(wú)沖擊型，有效地減小閥芯換向引起的噪聲和管道振動(dòng)。
- 穩(wěn)定性的工作
  高吸力、強(qiáng)力彈簧保證了污染工況下仍有良好的動(dòng)作穩(wěn)定性。
- 具備有符合各種標(biāo)準(zhǔn)的產(chǎn)品
  為對(duì)應(yīng)面向海外設(shè)備出口，可供應(yīng)UL/CSA認(rèn)定品和CE標(biāo)記產(chǎn)品。
