万福乐比例节流阀MQPPM22-350-G12/MEA1 节流阀(Choke valve)的外形结构与截止阀并无区别，只是它们启闭件的形状有所不同。
节流阀的启闭件大多为圆锥流线型，通过它改变通道截面积而达到调节流量和压力。节流阀供在压力降*的情况下作降低介质压力之用。介质在节流阀瓣和阀座之间流速很大，以致使这些零件表面很快损坏－即所谓气蚀现象。为了尽量减少气蚀影响，阀瓣采用耐气蚀材料（合金钢制造）并制成顶jian角为140～180的流线型圆锥体这还能使阀瓣能有较大的开启高度，一般不*在小缝隙下节流。由于节流阀的流量不仅取决于节流口面积的大小，还与节流口前后的压差有关，阀的刚度小，
故只适用于执行元件负载变化很小且速度稳定性要求不高的场合。
对于执行元件负载变化大及对速度稳定性要求高的节流调速系统
，必须对节流阀进行压力补偿来保持节流阀前后压差不变，从而达到流量稳定
