液压阀的基本结构主要包括阀芯、阀体和驱动阀芯在阀体内做相对运动的操纵装置。阀芯的主要形式有滑阀、锥阀和球阀；阀体上除有与阀芯配合的阀体孔或阀座孔外，还有外接油管的进、出油口和泄油口；驱动阀芯在阀体内做相对运动的装置可以是手调机构，也可以是弹簧或电磁铁，有些场合还采用液压力驱动。 　　在工作原理上，液压阀是利用阀芯在阀体内的相对运动来控制阀口的通断及开口的大小，以实现压力、流量和方向控制。 4WEH16F50B/OF6AG24NTZ4 4WEH16F50B/OF6AG24NTZ5 4WEH16F50B/OF6AG24NTZ5L 4WEH16F50B/OF6AW220-50NZ4 4WEH16F50B/OF6AW220-50NZ5 4WEH16F50B/OF6AW220-50NZ5L 4WEH16F50B/OF6AW220-50NEZ4 4WEH16F50B/OF6AW220-50NEZ5 4WEH16F50B/OF6AW220-50NEZ5L 4WEH16F50B/OF6AW220-50NETZ4 4WEH16F50B/OF6AW220-50NETZ5 4WEH16F50B/OF6AW220-50NETZ5L 4WEH16F50B/OF6AW220-50NTZ4 4WEH16F50B/OF6AW220-50NTZ5 4WEH16F50B/OF6AW220-50NTZ5L

　液压阀工作时，所有阀的阀口大小、阀进、出油口间的压差以及通过阀的流量之间的关系都符合孔口流量公式(q＝KA·Δp m)，只是各种阀控制的参数各不相同而已。
