Special control valves including: temperature and pressure reducing control valves, automatic recycle control valve, minimum flow control valves, etc.
特种控制阀有：减温减压调节阀、自动再循环控制阀、最小流量控制阀等。
For all elements other than flow elements or control valves, the true minimum, normal and maximum pressure and temperature ranges over which the element is expected to be effective are shown.
对于所有元件(流量元件或控制阀除外)，列出了元件预计起作用范围内的实际最小、正常和最大压力与温度？
This method can utilize the minimum control charge to reduce the currents of the primary power flow off-limit branches to the object boundary.
该方法可用最小的控制代价，使原越限支路电流降至目标电流范围。
