Rexroth 4WEH16J7X/6HG24N9ETK4/B10-910 Valve - Key Parameters

Rexroth 4WEH16J7X/6HG24N9ETK4/B10-910 Valve - FAQ

Q1: How is this valve different from the standard 4WEH16J7X?

A:​ The core technical specifications (16 mm size, J7X spool function, 350 bar pressure, high flow capacity) are identical. The difference is indicated by the -910​ suffix. This typically denotes a specific production variant, which may relate to a manufacturing batch, a minor design revision, specific factory testing, or a particular order configuration. The hydraulic function and performance remain the same.

Q2: What is the center function of the J7X spool?

A:​ The "J" series typically indicates a "tandem" or "float" center. In the neutral position, the pressure port (P) is blocked, and both actuator ports (A & B) are connected to the tank (T), allowing the connected cylinder or motor to move freely.

Q3: How is the valve controlled?

A:​ It is controlled by a double-solenoid pilot valve ("6HG24N9ETK4"). Energizing one of the 24V DC pilot solenoids shifts the main spool. De-energizing both allows springs to return it to the J7X (float) center position. The "/B10" part of the code relates to the spring centering characteristics.

Q4: What are the main performance ratings?

A:​ The main stage is rated for a maximum operating pressure of 350 bar. It is designed for high flow applications, with a capacity typically up to 300 l/min. It mounts on an ISO 4401-07 (CETOP 7) subplate.

Q5: Where can I get the exact specifications for this -910 variant?

A:​ For the definitive technical data sheet, performance curves, and any specific notes related to the -910​ variant, you must consult the official documentation for the exact order code R901480132. Always reference this full part number for procurement and technical support.
