    当和成对的液压缸一起使用时,通过把从负载较大的液压缸上的负载转移到负载较小的液压缸上,平衡阀将协助负载平衡。
    当和开式中位的方向控制阀一起使用时,也能够提供减速控制。
    提供的两种控制比4:1和10:1,通常较低的控制比将在容量大和惯性负载大的系统中提供更好的运动控制和稳定性。","CompanyName":"上海乾拓贸易有限公司","CompanyID":"153969","MarketPrice":"-1","PsOrder":"2789","PgID":"86","MaxOrder":"3","CityID":"3","City":"上海市","Address":"上海市","PropertysValue":"","HitNumber":"128","FrontShow":"0","IsCharges":"1","Year":"3","StarNum":"5","UpdateAndClientSort":"108434876","StandUrl":"/st153969","UpdateTime":"2019/1/14 13:16:02","TodayIsUpdate":"0","AttType":"0","AttState":"3","AttAddType":"1","IsSeoCreate":"0","IsOnlinePay":"0","MinPrice":"0.00","MaxPrice":"0.00","ClassID":"4275","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":"8641148","Picture":"2/20181212/636802166273689342350.jpg","PictureDomain":"img50","Name":"美国威格士液压阀/VICKERS效果图","Type":"","Descrip":"美国威格士液压阀/VICKERS效果图
