控制阀又称阀门，是流体运送系统中的控制部件，具有导流、截流、调节、节流、防止倒流、分流或溢流卸压等功能。可用于控制空气、水、蒸汽、各种腐蚀性化学介质、泥浆、液态金属和放射性物质等各种类型的流体活动。
控制阀按作用和用途分：
调节阀：用于调节介质的流量、压力等（调节阀、节流阀、减压阀）；
分流阀：用于分离、分配活混合介质（分配阀、疏水阀）；
**阀：用于介质超压时的**保护（**阀）；
截断阀：用于截断或接通介质流（闸阀、截止阀、隔膜阀、球阀、旋塞阀、蝶阀、柱塞阀、球塞阀、针型仪表阀等）
止回阀：用于阻止介质倒流。

Control valves, also known as valves, are control components in fluid transportation systems that have functions such as diversion, interception, regulation, throttling, prevention of backflow, diversion, or overflow pressure relief. It can be used to control various types of fluid activities such as air, water, steam, various corrosive chemical media, mud, liquid metals, and radioactive substances.
Control valves are classified according to their function and purpose:
Regulating valve: used to regulate the flow and pressure of the medium (regulating valve, throttle valve, pressure reducing valve);
Diverter valve: used for separating and distributing live mixed media (distribution valve, drain valve);
**Valve: used for * * protection in case of medium overpressure (* * valve);
Block valve: used to block or connect medium flow (gate valve, globe valve, diaphragm valve, ball valve, plug valve, butterfly valve, plunger valve, ball plug valve, needle instrument valve, etc.)
Check valve: used to prevent media backflow.
