Rexroth M-3SEW6C38 420MG24N9Z2 Mechanical Hydraulic Valve - 1/4 Inch NPT Port, 200°F Max Temperature

The Rexroth M-3SEW6C38 420MG24N9Z2 is a high-performance mechanical hydraulic valve designed for precision control in demanding industrial applications.

• Compact modular design with small size and light weight for integration in complex hydraulic systems
• Quick response with direct-acting proportional valve (response time <15ms) and integrated LVDT feedback
• Multifunctional operation including liquid flow direction switching, flow adjustment, and system unloading

• High pressure resistance with reinforced valve core and sealing components (tested for 110%-150% of rated value)
• Low leak design with FKM seal material resistant to high temperature and corrosion

• Electro-hydraulic proportional control with CANopen communication (±0.5% steady-state control accuracy)
• Flexible expansion capability for series and combined use with flow balance valves

Pipeline and Cleaning Requirements: Pipes must be thoroughly cleaned before installation to remove contaminants. Hot bent or welded pipes require pickling.

Electrical and Mechanical Cooperation: Check solenoid valve coil connections (24V DC) carefully to prevent burning. Mechanical zero position debugging requires adjusting the valve core to intermediate position with no input signal.

Parameter Control: Maintain oil viscosity (37~73cSt) and temperature (≤80°C). Avoid long-term full load operation (high-pressure duration ≤10% per minute).

Regular Inspection: Replace hydraulic oil after first 200 hours, then every 1000 hours. Clean oil filters regularly (NAS 1638 Level 6 cleanliness). Monitor seals and replace if leakage occurs.

• Spool Jams: Check for oil contamination and use special disassembly tools (R901500000) for cleaning
• Solenoid Fault: Measure coil resistance (standard 20Ω±5%) and check wiring for looseness or aging
