進口直動式電磁閥，Direct acting solenoid valve，通電時，電磁線圈產生電磁力把關閉件從閥座上提起，閥門打開；斷電時，電磁力消失，彈簧把關閉件壓在閥座上，閥門關閉。
進口直動式電磁閥適用于中性純凈氣體或液體，尤其是空氣、水、熱水、煤氣天燃氣、柴油等管路的控制系統；廣泛應用于切割設備、洗滌設備、機械制造、能源生物、醫療及環保水處理等行業中。
結構特點：
現場可自由安裝；動作響應迅速；閥體采用熱鍛成型工藝、體積小、外型美觀；
零壓力亦能打開主閥，低壓差流量大；采用原裝密封材料，壽命是同類產品十倍；
數控機床加工，確保電磁閥的精度與可靠性；
采用專門塑封線圈，提高閥的可靠性并能防水、防潮；
液體、氣體、油品可混合使用，提高閥的使用范圍。
應用范圍：
它廣泛應用在冶金、石油化工、制藥、食品、醫療、紡織等各個領域。適用于小口徑、低壓力的管道系統中。
產品特點：
體型小，外觀精美；線圈通電直接啟動閥芯，閥關閉靠彈簧復位；零壓啟動；泄漏量零；專制線圈，不易燒毀；閥體安裝方向無限制。
