Advantages and features of Rexroth hydraulic lift reversing valve
- Compact structure: Adopts a modular design, small size and light weight, adapts to the integration needs of complex hydraulic systems; some models (such as M-3SEW6U3X/420MG24N9K4/P) support high-pressure operation (maximum pressure of 420 bar).
- Quick Response: Direct-acting proportional valve (such as 4WRPEH series) has a response time of <15ms, integrated LVDT feedback, and achieves high-precision adjustment of flow and direction.
- Multifunction: Supports liquid flow direction switching, flow adjustment and system unloading functions, and is suitable for multiple scenarios such as engineering machinery and injection molding machines.
- High pressure resistance performance: The valve core and sealing components are made of reinforced materials, which can withstand short-term overload pressure (tested for some models with rated value of 110%-150%).
- Low Leak Design: Small reverse leakage, seal material (such as FKM) is resistant to high temperature and corrosion, and extends the service life of the valve.
- Electro-hydraulic proportional control: Supports CANopen communication, with steady-state control accuracy up to ±0.5%, adapting to the requirements of digital hydraulic systems.
- Flexible expansion: It can be used in series and combined to match the flow balance valve to achieve coordinated operations of multiple actuators.
Pipeline and cleaning requirements
Before installation, the pipes need to be thoroughly cleaned to ensure that there are no contaminants such as rust, sand, etc.; hot bent or welded pipes need to be pickled.
When tightening the flange, the force must be applied evenly across and the torque must comply with the standards (for example, the M-3SEW6U3X model adopts ISO 4401 interface specification).
Electrical and mechanical cooperation
The connection of the solenoid valve coil must be strictly checked (such as 24V DC) to avoid burning due to misconnection.
Mechanical zero position debugging requires adjusting the valve core to the intermediate position when there is no input signal to ensure smooth operation.
Parameter control
The viscosity of the oil must meet the requirements (recommended 37~73cSt), the oil temperature is ≤80℃ to avoid seal failure due to high temperature.
Long-term full load operation is prohibited, and the duration of high-voltage/high-speed is ≤10% per minute under intermittent working conditions.
Regular inspection
Replace the hydraulic oil after 200 hours of the first use, and then replace it every 1000 hours; clean the oil filter regularly to maintain the cleanliness of the oil (NAS 1638 Level 6).
Monitor the sealing status, and find oil leakage, the seal should be replaced in time or an external oil leakage pipe should be used to reduce the housing pressure.
Spool jams: Priority check for oil contamination, use special disassembly tools (such as order number R901500000) to clean the valve core if necessary.
Solenoid fault: Measure coil resistance (standard value 20Ω±5%), check for loose or aging of wiring.
Overall, Rexroth hydraulic lifting reversing valve is widely used in industrial control systems due to its high precision, pressure resistance and intelligent characteristics, but it requires strict implementation of installation specifications and maintenance procedures to ensure long-term and stable operation.
