Product Description
Rexroth Type 4WEH Series Pilot Operated Directional Spool Valves
Product Overview: The 4WEH Series represents the pinnacle of pilot-operated electro-hydraulic directional valves designed for high-power hydraulic systems. By utilizing a small direct-operated solenoid valve as a pilot to shift the main spool, this series can manage immense fluid flows with precision. It covers industrial sizes including Size 16 (NG16), Size 22 (NG22), Size 25 (NG25), and Size 32 (NG32).
This category highlights essential high-performance configurations: the 4WEH16J7X with J-spool function (P closed, A/B to T), the versatile 4WEH22E7 E-spool model, and the specific Rexroth Part Number R901108808. Renowned for switching stability and high-pressure tolerance, the 4WEH series is the premier choice for heavy-duty forging presses, metallurgical machinery, mining equipment, and offshore hydraulic systems.
Key Technical Advantages:
Massive Flow Regulation: The pilot-operated architecture allows control of ultra-high flow rates—up to 1100 L/min—while maintaining low electrical power consumption.
Flexible Control Options: Supports G24 (DC24V) solenoid control with various pilot and drain configurations, such as ET (Internal Pilot/Internal Drain) and K4 (Standard Connectors).
Smooth Switching (B10): Available with switching time adjusters (like the B10 sequence) to mitigate hydraulic shock during high-flow reversals, ensuring system integrity.
Superior Durability: Constructed with high-strength cast iron and precision-ground spools, ensuring high sealing integrity under operating pressures up to 350 Bar.
