原裝日本SMC電磁閥VNA411A-25A-4DZ：SMC電磁閥的主要特點電磁閥外漏堵絕，內漏易控，使用安全。內外泄漏是危及安全的要素。其它自控閥通常將閥桿伸出，由電動、氣動、液動執行機構控制閥芯的轉動或移動。這都要解決長期動作閥桿動密封的外泄漏難題；唯有電磁閥是用電磁力作用于密封在電動調節閥隔磁套管內的鐵芯完成，不存在動密封，所以外漏易堵絕。

原裝日本SMC電磁閥VNA411A-25A-4DZ：電動閥力矩控制不易，容易產生內漏，甚至拉斷閥桿頭部；電磁閥的結構型式容易控制內泄漏，直至降為零。所以，電磁閥使用特別安全，尤其適用于腐蝕性、有毒或高低溫的介質。3、SMC電磁閥系統簡單，便接電腦，價格低謙。電磁閥本身結構簡單，價格也低，比起調節閥等其它種類執行器易于安裝維護。更顯著的是所組成的自控系統簡單得多，價格要低得多。
