    PARKER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)。電磁閥本身結(jié)構(gòu)簡(jiǎn)單，價(jià)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(hù)。更顯著的是所組成的自控系統(tǒng)簡(jiǎn)單得多，價(jià)格要低得多。由于電磁閥是開關(guān)信號(hào)控制，與工控計(jì)算機(jī)連接十分方便。在當(dāng)今電腦普及，價(jià)格大幅下降的時(shí)代，電磁閥的優(yōu)勢(shì)就更加明顯。

    PARKER電磁閥作為過程控制系統(tǒng)的執(zhí)行元件之一，其安全性和可靠性早已為廣大客戶所*，為更好地服務(wù)于這一領(lǐng)域的石油開采，煉油，天然氣，石化電廠，水處理等行業(yè)應(yīng)用的多樣性和更可靠性的要求，及方便用戶和設(shè)計(jì)院的選型。

    派克電磁閥其特點(diǎn)和性能如下：模塊化結(jié)構(gòu)：PARKER電磁閥是用來控制流體的方向的自動(dòng)化基礎(chǔ)元件，屬于執(zhí)行器；通常用于機(jī)械控制和工業(yè)閥門上面，對(duì)介質(zhì)方向進(jìn)行控制，從而達(dá)到對(duì)閥門開關(guān)的控制。

PARKER派克電磁閥安裝注意
1、安裝時(shí)應(yīng)注意閥體上箭頭應(yīng)與介質(zhì)流向*。不可裝在有直接滴水或?yàn)R水的地方。電磁閥應(yīng)垂直向上安裝；
2、電磁閥應(yīng)保證在電源電壓為額定電壓的15%-10%波動(dòng)范圍內(nèi)正常工作；
3、電磁閥安裝后，管道中不得有反向壓差。并需通電數(shù)次，使之適溫后方可正式投入使用；
4、電磁閥安裝前應(yīng)*清洗管道。通入的介質(zhì)應(yīng)無雜質(zhì)。閥前裝過濾器；
5、當(dāng)電磁閥發(fā)生故障或清洗時(shí)，為保證系統(tǒng)繼續(xù)運(yùn)行，應(yīng)安裝旁路裝置。
