Parker派克D41FH系列導(dǎo)式比例換向閥到極為復(fù)雜的自控系統(tǒng)中所用的各種換向閥，其品種和規(guī)格繁多， 換向閥的公稱通徑從極微小的儀表閥大通徑達(dá)10m的工業(yè)管路用閥。換向閥可用于控制水、蒸汽、油品、氣體、泥漿、各種腐蝕性介質(zhì)、 液態(tài)金屬和放射性流體等各種類型流體的流動(dòng) ，換向閥的工作壓力可從0.0013MPa到1000MPa 的超壓，工作溫度從-269℃的超低溫到1430℃的溫。換向閥的控制可采用多種傳動(dòng)方式， 如手動(dòng)、電動(dòng)、液動(dòng)、氣動(dòng)、蝸輪、電磁動(dòng)、電磁--液動(dòng)、電--液動(dòng)、氣--液動(dòng)、正齒輪、傘齒輪驅(qū)動(dòng)等；可以在壓力、溫度或其它形式傳感信號(hào)的作用下， 按預(yù)定的要求動(dòng)作，或者不依賴傳感信號(hào)而進(jìn)行簡(jiǎn)單的開啟或關(guān)閉，換向閥依靠驅(qū)動(dòng)或自動(dòng)機(jī)構(gòu)使啟閉件作升降、滑移、旋擺或回轉(zhuǎn)運(yùn)動(dòng)， 從而改變其流道面積的大小以實(shí)現(xiàn)其控制功能。
