美國(guó)PARKER派克二位二通直動(dòng)式電磁閥技術(shù)規(guī)范：
派克電磁閥適用介質(zhì)：冷凍凍設(shè)備電磁閥經(jīng)專門設(shè)計(jì)，能承受低于-320攝氏度的惡劣溫度，用于控制冷凍液。由于現(xiàn)有的密封材料用于如此低的溫度，克提供專門設(shè)計(jì)的用于氣密封截?cái)嚯姶砰y。
PARKER直動(dòng)式電磁閥電壓：DC-6,12,24,120,125（可按需求提供電壓）；AC-24/60,110/120-50/60,220/240-50/60,440/480-50/60
線圈：標(biāo)準(zhǔn)F級(jí)，H級(jí)可選。
其它：額定溫度 AC交流：zui大-320-150°F DC交流：zui大-320-150°F 環(huán)境：32-77°F（標(biāo)準(zhǔn)）
安裝：重要：閥下游管道的內(nèi)徑不得大于電磁閥標(biāo)稱直徑，防止CO2膨脹導(dǎo)致閥結(jié)冰。電磁閥帶托架，便于直接安裝，另配一個(gè)NPT1/8接口，用于間接安裝。
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電磁閥從原理上分為三大類：
派克直動(dòng)式電磁閥
原理：通電時(shí)，電磁線圈產(chǎn)生電磁力把關(guān)閉件從閥座上提起，閥門打開；斷電時(shí)，電磁力消失，彈簧把關(guān)閉件壓在閥座上，閥門關(guān)閉。
特點(diǎn)：在真空、負(fù)壓、零壓時(shí)能正常工作，但通徑一般不超過25mm。
派克分步直動(dòng)式電磁閥
原理：它是一種直動(dòng)和先導(dǎo)式相結(jié)合的原理，當(dāng)入口與出口沒有壓差時(shí)，通電后，電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起，閥門打開。當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí)，通電后，電磁力先導(dǎo)小閥，主閥下腔壓力上升，上腔壓力下降，從而利用壓差把主閥向上推開；斷電時(shí)，先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動(dòng)關(guān)閉件，向下移動(dòng)，使閥門關(guān)閉。
特點(diǎn)：在零壓差或真空、高壓時(shí)亦能可*動(dòng)作，但功率較大，要求必須水平安裝。
PARKER先導(dǎo)式電磁閥
原理：通電時(shí)，電磁力把先導(dǎo)孔打開，上腔室壓力迅速下降，在關(guān) 閉件周圍形成上低下高的壓差，流體壓力推動(dòng)關(guān)閉件向上移動(dòng)，閥門打開；斷電時(shí)，彈簧力把先導(dǎo)孔關(guān)閉，入口壓力通過旁通孔迅速腔室在關(guān)閥件周圍形成下低上高的壓差，流體壓力推動(dòng)關(guān)閉件向下移動(dòng)，關(guān)閉閥門。
特點(diǎn)：流體壓力范圍上限較高，可任意安裝（需定制）但必須滿足流體壓差條件。
