Working Principle:

• Signal Input and Conversion: The valve receives an electrical signal from a control system, which is usually in the form of current or voltage. The magnitude of this signal is proportional to the desired flow rate. An electro - mechanical conversion device, such as an electromagnetic coil or a torque motor, transforms the input electrical signal into a mechanical force or torque. For example, when an electromagnetic coil is energized, it generates a magnetic field that attracts or repels an armature connected to the valve spool, creating a force that moves the spool.
• Spool Displacement Control: The mechanical force or torque acts on the spool, causing it to move. The displacement of the spool is directly proportional to the magnitude of the input electrical signal. As the spool moves, it changes the area of the orifice inside the valve. When the spool moves in one direction, the orifice area increases, reducing the resistance to fluid flow through the valve, and thus increasing the flow rate. Conversely, when the spool moves in the opposite direction, the orifice area decreases, and the flow rate decreases.

 

Application Scenarios:

• Industrial Manufacturing: In injection molding machines, it precisely controls the flow rate of hydraulic oil to regulate the speed and pressure of actions like mold clamping, injection, and pressure holding, ensuring the precision and quality of plastic products. In the pneumatic fixtures of automated production lines, it accurately controls the flow rate of compressed air to precisely control the clamping force and action speed of the fixtures.
• Energy Sector: In refineries, it is used to precisely control the flow rates of various petroleum fractions and chemical raw materials in pipeline transportation systems, ensuring the accurate proportioning and stable supply of materials. In thermal power plants, it is used in the fuel oil system to precisely control the flow rate of fuel oil and adjust the fuel supply in real - time according to the load requirements of the generator set.
• Transportation: In the fuel injection systems of automobile engines, it precisely controls the fuel injection volume to achieve the best fuel economy and exhaust emission performance. In the braking systems of subways and high - speed railways, it is used to precisely control the flow rate of brake fluid and adjust the braking pressure in real - time based on factors such as the running speed and load of the train.
• Aerospace: In the flight control systems of aircraft, it is used to precisely control the flow rate of hydraulic oil to drive the actuators of the flight control surfaces and achieve precise control of the aircraft's attitude. In the fuel control systems of aero - engines, it precisely controls the flow rate and injection angle of fuel and adjusts the fuel supply in real - time according to the working states of the engine to improve fuel efficiency and reduce emissions.
