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(nèi)漏易控，使用安全。內(nèi)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(zhí)行機構(gòu)控制閥芯的轉(zhuǎn)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(diào)節(jié)閥隔磁套管內(nèi)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(chǎn)生內(nèi)漏，甚至拉斷閥桿頭部；電磁閥的結(jié)構(gòu)型式容易控制內(nèi)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(zhì)。3、SMC電磁閥系統(tǒng)簡單，便接電腦，價格低謙。電磁閥本身結(jié)構(gòu)簡單，價格也低，比起調(diào)節(jié)閥等其它種類執(zhí)行器易于安裝維護。更顯著的是所組成的自控系統(tǒng)簡單得多，價格要低得多。
