常用性能编辑
一般调速阀不带温度补偿， 可用在机床、动力头滑台及类似设备上 ；另一种带温度补偿装置，把转动式的阀芯改成薄刃结构的滑阀式阀芯以减少温度对流量的影响。因为节流阀的节流缝隙越短 ，温度对流量的影响就越小， 这是一种受温度影响较小的流量控制阀。或者是在调节螺钉与阀芯之间加一根用热敏性较大材料制成的感温杆， 温度变化时，利用阀芯的热胀冷缩来自动调节阀芯和阀体间形成的节流面积。带温度补偿的调速阀通常用在对调速性能要求很高的设备上。 [2] 
区别编辑
节流阀与调速阀的区别
1、节流阀，是调节和控制阀内开口的大小直接限制流体通过的流量达到节流的目的。由于是强制受阻节流，所以节流前后会产生较大的压力差，受控流体的压力损失比较大，也就是说节流后的压力会减小。
2、调速阀，是在节流阀节流原理的基础上，又在阀门内部结构上增设了一套压力补偿装置，改善的节流后压力损失大的现象，使节流后流体的压力基本上等同于节流前的压力，并且减少流体的发热。 调速阀一般分二通调速阀和三通调速阀，二通调速阀是由一个定差减压阀和一个节流阀串联组成，三通调速阀是由一个定差溢流阀和一个节流阀并联组成，但它们都有一个共同的特性：即保持节流阀进、出油口的压差基本恒定，这样通过节流阀的流量只和阀口开度A有关，与负载压力波动无关 调速阀貌似也叫补偿阀 节流阀就像一个水龙头，你拧的大了水就流的多，但是在水龙头拧相同圈数的情况下管道里的压力高，水就流的多，压力小水就流的少。但调速阀不是不管管道里压力有多高（相对）在水龙头拧相同圈数时，水流的一样多。
