festo電磁閥，費斯托（FESTO）電磁閥，德國FESTO,FESTO
氣動自動化域的 Festo AG & Co. KG 是世界上的氣動元件、組件和系統的廠商。公司總部位于德國 Esslingen。費斯托 （） 有限公司是它于 1993 年在大陸設立的獨資子公司
FESTO是世界氣動*家通過ISO 9001認證的企業。FESTO的品牌包含許多方面,主要表現在智能化和易操作的產品設計、使用壽命長的產品、持久的效率優化以及化和
電磁閥是利用電能流經線圈產生電磁吸力將閥芯（克服彈簧或自重力）吸引.分常開與常閉兩類.通常用于切斷油,水,氣等物質的流通.配合壓力,溫度傳感器等電氣設備實現自動控制. 電磁閥大體有兩種 1.電磁閥：采用分步直接式結構，使電磁力直接作用到主閥芯，在壓差等于零或真空時，亦能可靠動作，閥芯磨損能自動補償，大大地延長了使用壽命，低功耗，無泄漏，適用于制冷劑、蒸氣、水、空氣、油、真空等介質。 2.2. 特種電磁閥：超低溫電磁閥（適用于－196℃液氮）、高溫電磁閥（zui高溫度可達450℃）、防爆電磁閥（得把適用于易爆易燃的危險環境）、塑料王電磁閥（特別適用于酸堿、超凈流體介質）、信號電磁閥、常開電磁閥、單向電磁閥、帶手動電磁閥等。 簡單來講所有的電磁閥都是將電信號轉成氣的動作（就是信號的轉換）

電磁閥就像是自來水開關,不過它是由電來控制它的通和斷.
要看是什么了.總的來說,就是閥門.用電來控制開閉.
它在液壓設備中用得較多，主要是控制油缸的動作，用于自動控制設備中的，也有氣動的，由空壓機來供氣。
給你個通俗的解釋：由電磁鐵控制的閥門簡稱為。這類閥門廣泛用于自動控制系統。是控制--執行的關鍵元件。
