REXROTH液控单向阀R900403578 SV10PA2-4X/V

节流阀是通过改变节流截面或节流长度以控制流体流量的阀门。将节流阀和单向阀并联则可组合成单向节流阀。节流阀和单向节流阀是简易的流量控制阀，在定量泵液压系统中，节流阀和溢流阀配合，可组成三种节流调速系统，即进油路节流调速系统、回油路节流调速系统和旁路节流调速系统。节流阀没有流量负反馈功能，不能补偿由负载变化所造成的速度不稳定，一般仅用于负载变化不大或对速度稳定性要求不高的场合。

SV系列液控单向阀液控单向阀有一个开启比的参数,同样结构形式的阀,外泄式的比内泄时的开启比要大.在选择液控单向阀时要注意开启比要与油缸的面积比匹配要比油缸的面积比大,目前使用的油缸的面积比一般在2左右,而目前现有的液控单向阀产品的开启比都比2大得多,都可以直接选择不必进行匹配计算.但如果由于特殊情况需要采用大面积比的油缸时,就要考虑阀的开启比的问题

SV型阀是锥阀结构的液控单向阀,它可以在关闭方向开启而让油液自由流动.

此类阀用于有压液压回路部分的隔离,当管路破裂时,作为防止负载失压的安全措施,或避免执行器在液压闭锁时的爬行或漂移.
