(1) 調壓范圍：它是指減壓閥輸出壓力P2的可調范圍，在此范圍內要求達到規定的精度。調壓范圍主要與調壓彈簧的剛度有關。
(2) 壓力特性：它是指流量g為定值時，因輸入壓力波動而引起輸出壓力波動的特性。輸出壓力波動越小，減壓閥的特性越好。輸出壓力必須低于輸入壓力—定值才基本上不隨輸入壓力變化而變化。
(3) 流量特性：它是指輸入壓力—定時，輸出壓力隨輸出流量g的變化而變化的持性。當流量g發生變化時，輸出壓力的變化越小越好。一般輸出壓力越低，它隨輸出流量的變化波動就越小。                                                                                                                                               力士樂溢流閥一種液壓壓力控制閥。在液壓設備中主要起定壓溢流作用，穩壓，系統卸荷和安全保護作用。定壓溢流作用：在定量泵節流調節系統中，定量泵提供的是恒定流量。當系統壓力增大時，會使流量需求減小。此時溢流閥開啟，使多余流量溢回油箱，保證溢流閥進口壓力，即泵出口壓力恒定（閥口常隨壓力波動開啟）。穩壓作用：溢流閥串聯在回油路上，溢流閥產生背壓，運動部件平穩性增加。系統卸荷作用：在溢流閥的遙控口                                                                                     DBDS6K-1X/100
