利用调节阀芯和阀体间的节流口面积和它所产生的减压阀局部阻力对流量进行调节，从而控制执行元件的运动速度。流量控制阀按用途分为5种。

　　(1)节流阀：在调定节流口面积后，针型阀能使载荷压力变化不大和运动均匀性要求不高的执行元件的 呼吸阀运动速度基本上保持稳定。

　　(2)调速阀：在载荷压力变化时能保持调节阀节流阀的进出口压差为定值。这样，在节流口面积调定以后，不论载荷压力如何变化，调速阀都能保持通过节流阀的流量不变，从而使执行元件的运动速度稳定。

　　(3)分流阀：不论载荷大小，能使同一油源的两个锻钢阀门执行元件得到相等流量的为等量分流阀或同步阀；得到按比例分配流量的为比例分流阀。

　　(4)集流阀：作用与分流阀相反，使流入集流阀的流量按比例分配。

　　(5)分流集流阀：兼具分流阀和集流阀两种功能。

            An adjustment between the spool and valve orifice area and it generates the local resistance to the flow is regulated 柱塞阀 to control the velocity of actuators. By use of flow control valve is divided旋塞阀 into five kinds. (1) throttle: throttle valve area in which it is set, after little change in the load pressure and motion even less demanding implementation of the components of velocity are basically stable. (2) Control Valve: pressure changes in the平衡阀 load when the throttle valve to maintain the pressure drop for the given value. Thus, it is set after the orifice area, regardless of 呼吸阀how the changes in load pressure, control valve can maintain constant flow through the throttle, so that the velocity of actuators stability. (3) shunt valve: no matter loads, make the implementation of the same oil source of the two components are equal疏水阀 for equal flow diversion valve or simultaneous valve; be prorated for the proportion of shunt flow valve. (4) Set flow valve: the role of contrast with the shunt valve to flow into the set of proportion to the flow valve. (5) split Combining Valve: both shunt valve and flow valve assembly of two functions.
