OEM Industrial Oil Vacuum Pump Solenoid Reversing Valve DG4V-3-0A-U-H-100-3
Working principle:The electromagnetic reversing valve generates a magnetic field through the electromagnetic coil, which controls the movement of the valve core, thereby changing the position of the valve core, and then changing the flow of fluid. When the electromagnetic coil is energized, the magnetic field acts on the spool, making it move to a specific position, changing the connection state of the valve channel, and making the fluid flow to the corresponding outlet.
Structure and composition:Electromagnetic directional valve is usually composed of electromagnetic coil, valve core, spring, valve body and valve seat. The solenoid coil is the control part of the valve and controls the position of the spool by energizing or deenergizing it. The spool is a key part of controlling the flow of fluid, and depending on the location of the spool, the fluid can flow to different channels and outlets
Control mode:The control mode of the solenoid reversing valve can be realized by two types of DC solenoid valve and AC solenoid valve. Dc
solenoid valves usually use DC power supply to control the position of the spool by changing the polarity of the current. Ac
solenoid valves usually use AC power supply to control the position of the spool by changing the frequency of the current
Application:Electromagnetic directional valves are widely used in various equipment and machinery in hydraulic systems, such as industrial machinery, agricultural machinery, construction equipment, automotive and aviation equipment. They are commonly used to control fluid flow in hydraulic cylinders, hydraulic motors, hydraulic drive systems, and hydraulic control systems
Functions :Direction control: By controlling the position of the spool, the electromagnetic reversing valve can achieve the control of the forward, reverse or neutral direction of the fluid.
Flow control: By adjusting the opening of the spool, the electromagnetic reversing valve can control the flow of the fluid.
Pressure control: Some solenoid directional valves have a pressure control function to adjust the pressure in the hydraulic system as needed.
Characteristics: Fast response: The response speed of the electromagnetic reversing valve is usually very fast, and the reversing operation can be completed in milliseconds.
Reliability: Electromagnetic directional valves usually have stable performance and reliable sealing, and can operate stably in harsh working environments for a long time.
