Rexroth 4WEH16E7X/6HG24N9ETK4/B10 Valve - FAQ

Q1: What is the typical center function of an "E" series spool like the E7X?

A:​ "E" series spools often have a unique center function. A common configuration is that in the neutral position, the pressure port (P) is connected to both actuator ports (A & B) and also to the tank (T). This applies pressure to both sides of an actuator while allowing the pump to unload. The exact E7X symbol must be verified.

Q2: Why is the flow capacity higher than smaller valves?

A:​ This valve has a 16 mm nominal size, meaning larger internal flow paths. Combined with its two-stage, pilot-operated design, it is built to control significantly higher flow rates, often in the range of 200-300 l/min, making it suitable for larger hydraulic systems.

Q3: How is the valve controlled?

A:​ It is controlled by a double-solenoid pilot valve ("6HG24N9ETK4"). Energizing one of the 24V DC solenoids shifts the main spool. De-energizing both returns it to the E7X center position via springs. The "/B10" suffix typically specifies the spring centering characteristic.

Q4: What are the key performance specifications?

A:​ Main stage maximum pressure is typically 350 bar. Maximum flow is in the high range (e.g., 200-300 l/min). It mounts on an ISO 4401-07 (CETOP 7) subplate. The exact ratings depend on the E7X spool variant.

Q5: Where can I find complete technical details?

A:​ For the complete datasheet, including the exact E7X center symbol, flow-pressure curves, pilot pressure requirements, and electrical data, consult the official documentation for order code R901108754.
