溢流閥是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：在溢流閥的遙控口串接溢小流量的電磁閥，當電磁鐵通電時，溢流閥的遙控口通油箱，此時液壓泵卸荷。溢流閥此時作為卸荷閥使用。
安全保護作用：系統正常工作時，閥門關閉。只有負載超過規定的極限（系統壓力超過調定壓力）時開啟溢流，進行過載保護，使系統壓力不再增加（通常使溢流閥的調定壓力比系統zui高工作壓力高10%～20%）。
實際應用中一般有：作卸荷閥用，作遠程調壓閥，作高低壓多級控制閥，作順序閥，用于產生背壓（串在回油路上）。
溢流閥一般有兩種結構：1、直動型溢流閥 。2、先導式溢流閥。
對溢流閥的主要要求：調壓范圍大，調壓偏差小，壓力振擺小，動作靈敏，過載能力大，噪聲小。
