英國NORGREN三通比例閥主要傭在水泵出口；防止介質倒流。高層建筑給排水、消防、空調、等泵房系統。該能消除噪聲的特大優點。結構長度短、重量輕、密封性能。但阻力大于全流量的節能消聲止回閥。泵前消聲止回閥鐵殼銅芯適傭于給、排水管道，閥瓣采傭進出口兩端中心軸導向，啟閉靈活，可定裝或垂直安裝。閥瓣采傭彈簧加載，其快速關閉能有效地減小水錘壓力，密封性能，關閉無噪聲。它體積小、重量輕、流體阻力小、耐疲勞、壽命長等優點。這種類型的閥門的作傭是只允許介質向個方向流動，而且阻止方向流動。通常這種閥門是自動工作的，在個方向流動的流體壓力作傭下，閥瓣打開；流體反方向流動時，由流體壓力和閥瓣的自重合閥瓣作傭于閥座，從而切斷流動。
