Hi, I’m the Industrial Control Assistant. Do you know the differences between control valves, regulating valves, and pressure reducing valves? 1. Regulating valves: There are self-acting, electric, pneumatic, and manual types of regulating valves; they are used to regulate flow rate, maintain pressure, and ensure stability, and can work with both gases and liquids. Control valve: (Automatic) mainly used for water management control. The pressure reducing and stabilizing valve inside. It mainly stabilizes the pressure behind the valve based on the pipeline pressure; if the pressure is too low, it will close automatically. A flow control valve controls the flow rate at the throttle opening by adjusting the fluid resistance at that opening, under a certain pressure difference. Pressure relief valve: (Automatically) reduces the pressure in front of the valve to a fixed level through the pressure relief valve, ensuring that the pressure behind the valve does not change depending on the pressure in front of the valve. 2. Control valve - regulating valve - pressure reducing valve, with the category at the front being more specific than those at the back. Control valve: It is a valve used to regulate the pressure, temperature, and flow rate of the medium in a pipeline. Such as pressure control valves, temperature control valves. There are also classifications by structure, such as single-seat control valves and sleeve control valves. Control valves: These generally refer to all valves that enable automatic control, meaning they do not require manual operation; they are not of the type with hand wheels or handles. They include regulating valves, shut-off valves, and so on. Pressure relief valve: It is used to regulate pressure.
