Z2FS6-2-44/2QV REXROTH节流阀
节流阀特点
1、构造较简单，便于制造和维修，成本低。
2、调节精度不高，不能作调节使用。
3、密封面易冲蚀，不能作切断介质用。
4、密封性较差。
节流阀按通道方式可分为直通式和角式两种；按启闭件的形状分，有针形、沟形和窗形三种。节流阀的安装与维护应注意以下事项：
该阀经常需要操作，因此应安装在易于方面便操作的位置上。
安装时要注意介质方向与阀体所标箭头方向保持一致。
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。

Z2FS6-2-44/2QV REXROTH节流阀
对节流阀的性能要求是：
·流量调节范围大，流量一压差变化平滑；
·内泄漏量小，若有外泄漏油口，外泄漏量也要小；
·调节力矩小，动作灵敏。
节流阀(throttle 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。节流阀供在压力降极大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－即所谓汽蚀现象。为了尽量减少汽蚀影响，阀瓣采用耐汽蚀材料（合金钢制造）并制成顶尖角为140～180的流线型圆锥体，这还能使阀瓣能有较大的开启高度，一般不推荐在小缝隙下节流。
