比例阀和普通阀区别:
1、普通阀是不能按比例进行连续阶跃控制,是纯粹的单一动作式开关阀,其阀开口方向、开口量或弹簧设定力都是一定的,不能根据实际情况变化而变化。
2、比例阀是按比例进行连续阶跃控制,根据实际情况变化采集回的信息对目标进行自动补偿控制,其阀开口方向、开口量或弹簧设定力都是随动的,实现一系列连续可控的随动变化的动作。","CompanyName":"成都善荣机电设备有限公司","CompanyID":"163458","MarketPrice":"-1","PsOrder":"3112","PgID":"86","MaxOrder":"4","CityID":"248","City":"成都市","Address":"成都市","PropertysValue":"","HitNumber":"345","FrontShow":"0","IsCharges":"1","Year":"3","StarNum":"5","UpdateAndClientSort":"108085160","StandUrl":"/st163458","UpdateTime":"2018/5/16 16:40:42","TodayIsUpdate":"0","AttType":"0","AttState":"3","AttAddType":"0","IsSeoCreate":"0","IsOnlinePay":"0","MinPrice":"0.00","MaxPrice":"0.00","ClassID":"4278","productonlinetime":"1900/1/1 0:00:00","OnLineDate":"1900/1/1 0:00:00","DownLineDate":"1900/1/1 0:00:00","BrandPicDomin":"","BrandPicName":"","BrandProperty":"","PBrandID":"0","IsHadVideo":"0","VideoTime":"0","ShowPrice":"0.00"},{"ID":"2533255","Picture":"2/20120614/634752640072968750.jpg","PictureDomain":"img43","Name":"FESTO方向流量比例阀,FESTO电气比例阀,FESTO比例阀","Type":"LRB-1/2-D-7-O-K3-MIDI","Descrip":"FESTO方向流量比例阀,FESTO电气比例阀,FESTO比例阀
