A throttle valve is a universal valve used to control fluid flow, usually installed on pipelines. Its function is to adjust the flow rate by changing specific parameters of the fluid (such as flow rate, pressure, cross-sectional area, etc.). In many hydraulic or pneumatic systems, throttle control valve are essential components. It can directly adjust the flow rate of the fluid to meet certain specific requirements. The principle of a throttle valve is also very simple. The basic principle is to reduce or increase the pressure inside the pipeline by reducing or increasing it, thereby controlling the flow rate. Generally, the flow rate is adjusted by the aperture of the orifice. In this way, the effect of throttling can be effectively achieved. There are also many types of throttle valves, such as piston type throttle valves that need continuous adjustment, and for those that need to be controlled according to a fixed flow rate, they can be controlled using a flow meter that needs to b…
