Parker先導(dǎo)式比例換向閥D41FH系列東莞*

Parker派克D41FH系列先導(dǎo)式比例換向閥是管路流體輸送系統(tǒng)中控制部件，它是用來改變通路斷面和介質(zhì)流動(dòng)方向，具有導(dǎo)流、截止、調(diào)節(jié)、節(jié)流、止回、分流或溢流卸壓等功能。 用于流體控制的換向閥，從zui簡單的截止閥到極為復(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至通徑達(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 的超高壓，工作溫度從-269℃的超低溫到1430℃的高溫.
