    • Please keep the oil clean.
    • The (one-way) throttle valve has the advantages of simple structure, convenient adjustment, and low price, but because there is no pressure compensation, the flow stability is poor, and it is suitable for occasions where the load changes little or the speed control accuracy is not high.
    • Throttle valve should not be opened too small during use, otherwise, it is easy to block and cause the actuator to crawl.

     Hydraulic flow control valve applications

    Tips: Flow Control Valve vs. Air Control Valve

    A flow control valve and an air control valve are two distinct types of valves used in different applications. A flow control valve is primarily used to regulate the flow rate of fluids or gases within a system. It allows for precise adjustment of the flow rate by controlling the opening or closing of the valve. Flow control valves are commonly found in hydraulic systems, pneumatic systems, and plumbing systems, among others. They play a crucial role in controlling the speed, force, or movement of actuators, and they ensure the desired flow rates are maintained.

    On the other hand, an air control valve is specifically designed for controlling the flow of compressed air in pneumatic systems. Compressed air is commonly used in various industrial applications, and air control valves enable the precise regulation of air flow, pressure, and direction. These valves can be used for tasks such as actuating pneumatic cylinders, controlling air motors, or operating pneumatic tools. Air control valves are essential for maintaining the desired air flow rates, controlling the movement of pneumatic actuators, and ensuring efficient and reliable pneumatic system operation.

    In summary, while a flow control valve regulates the flow rate of fluids or gases in general, an air control valve is specifically designed for controlling the flow of compressed air in pneumatic systems. They serve different purposes in different types of systems, but both are crucial for achieving precise control and efficient operation.
