4WE6-6X Electromagnetic Reversing Valve
4WE6-6X electromagnetic reversing valve is a directional control valve widely used in hydraulic systems. It belongs to the standard product series of brands such as Rexroth. The following is a detailed introduction to this model of electromagnetic reversing valve:
1. Basic parameters and characteristics
Model structure: 4WE6-6X4: represents 4 working oil ports (P, A, B, T).
WE6: Indicates the series and specifications of the valve (diameter is 6mm).
6X: Indicates the functional code and mounting surface standards of the valve (such as ISO 4401).
Diameter: 6mm, suitable for small and medium flow hydraulic systems.
Control method: electromagnetic control, drive valve core reversal through solenoid.
Installation surface standard: complies with international standards such as ISO 4401, CETOP-RP 121H, etc., for easy interchange and installation.
Valve core function: According to the model suffix (such as A, B, C, D, etc.), a variety of slide valve functions (such as O, H, Y, etc.) are provided to meet different control needs.
Electromagnet type: wet DC or AC solenoid, optionally with removable coils for easy maintenance.
Pressure level: The working pressure can reach 350bar (refer to the product sample for details).
Flow range: The flow rate is usually 80L/min (refer to the product sample for details).
Protection level: usually IP65, suitable for general industrial environments.
2. Working principle
Electromagnetic drive: When the solenoid is powered on, a magnetic field is generated to attract the valve core, push the valve core to move to the designated position, change the oil port connection state, and realize the flow direction control of hydraulic oil.
Spring Reset: After power is disconnected, the valve core returns to the median or initial position under the action of the return spring.
Manual emergency operation: Some models are equipped with manual emergency operation devices that can manually switch the valve core position when the solenoid fails.
3. Application areas
Industrial equipment: such as injection molding machines, die casting machines, machine tools, etc., used to control the movement of hydraulic cylinders and hydraulic motors.
Construction machinery: such as excavators, cranes, etc., used to control movements such as walking, rotating, and lifting.
Agricultural machinery: such as tractors, harvesters, etc., used to control hydraulic suspension systems and steering systems.
Other fields: such as ships, aerospace, metallurgy, etc., used in various hydraulic control systems.
4. Selection and precautions
Function selection: Select appropriate slide valve functions according to system needs (such as O-type median closure, H-type median unloading, etc.).
Voltage selection: Select DC (DC) or AC (AC) solenoid according to the power supply conditions and confirm the voltage level (such as DC24V, AC220V, etc.).
Installation method: Confirm the installation surface standards (such as ISO 4401) and connection methods (such as plate connection, tube connection, etc.).
Environmental conditions: Choose the appropriate protection level and sealing materials (such as nitrile rubber, fluoroelastomer, etc.) according to the use environment.
5. Installation and maintenance
Check before installation: Make sure that the valve model, specifications and function meet the system requirements, and check whether the valve body and solenoid are intact.
Installation direction: Install according to the flow direction mark on the valve body to ensure the oil port is connected correctly.
Electrical connection: Connect the solenoid coil according to the electrical drawings, paying attention to the polarity and wiring method.
Debugging and testing: Check whether the solenoid is flexible before powering on, gradually increase the pressure during debugging, and observe the working status of the valve.
Daily maintenance: Regularly check the working status of the solenoid and valve core, clean the valve body surface, and prevent oil contamination.
6. FAQs and Solutions
Valve spool stagnation: Check the cleanliness of the oil, clean the valve body and valve spool, and replace the worn seals.
The electromagnet does not move: check the power supply and wiring, measure the coil resistance, and replace the damaged electromagnet.
Leakage: Check the wear of the valve body and seal, tighten the connecting bolts, and replace the seal if necessary.
Excessive noise: Check the oil viscosity and system pressure, adjust the valve installation position, and reduce vibration.
