結(jié)構(gòu)特點：1、該閥采用先進的雙閥座機構(gòu)，主副復閥滿足高壓力、大排量而體積小。
2、對凝結(jié)水德產(chǎn)生量 適應(yīng)性強， 可間歇排水，汽水分離可靠。
3、背壓率高（≤80%），可有效回收凝結(jié)水。
4、閥內(nèi)全不銹鋼零件全安裝在閥蓋上，維修方便，防腐蝕性強
Introduction:ER steam trap with two valve bases enjoys
Extensive applications in petroleum chemical industries。Printing pharmacy，textile
Foods and all kinds of high and middle pressure steam equipments.
Structures：1.This kind of trap adopts two valve bases；bath can meet the need of high pressure ,large discharging amount and small volume
