Rexroth 4WE6D62 EW230N9K4 Hydraulic Directional Spool Valve High Efficiency Original New

The special flow channel design reduces internal impedance and pressure loss, improving energy efficiency by more than 30%. This design also reduces oil temperature, delaying hydraulic oil deterioration and extending system life.

Valve core switching time is controlled in milliseconds to meet high-frequency action requirements. The proportional valve with integrated LVDT feedback has a response time of less than 15ms.

Oil-immersed electromagnetic action design buffers pressure shocks for high operating stability. The valve core and valve seat provide excellent sealing with low leakage risk, making it suitable for harsh environments including dust and vibration.

Supports multiple control methods:

• Electromagnetic control for automated production lines
• Hydraulic/pneumatic control for high-pressure and high-temperature scenarios
• Proportional valve enables stepless adjustment of flow and pressure

Working pressure reaches 315bar with special material design for various hydraulic systems. Suitable for engineering machinery, wind power pitch control, steel rolling mills, and other industrial applications.

• Manual operation is limited to simple scenarios - avoid frequent switching
• Electromagnetic control requires voltage-stabilized power supply to prevent coil damage
• Hydraulic/pneumatic operation requires dedicated actuator

• Regularly check oil cleanliness (recommended NAS 1638 level 6 standard)
• Check coil resistance (standard value 20Ω±5%)
• Inspect seals every 500 hours to prevent leakage

• For high-pressure scenarios, prefer models with hydrostatic unloading technology
• Closed-loop control systems require high-precision sensors for steady-state accuracy (±0.5%)

• Ensure junction box seal remains intact for waterproof and dustproof performance
• In high temperature environments (>80°C), recommend adding heat sink

• Use original disassembly tools (R901500000) for spare part replacement
• Confirm mid-position function (O/Y/H type) matches equipment requirements before system debugging
