REXROTH 4WE10D33/CW230N9K4 R900912496

Rexroth 4WE 10 D33/CW230N9K4 Hydraulic Valve

Description

This is a direct-operated directional spool valve, model 4WE 10 D33/CW230N9K4, from Bosch Rexroth. It is a size NG10 valve with a standard porting pattern according to ISO 4401-05-04-0-94 (CETOP 5). This 4/3-way valve is solenoid-actuated and designed for high reliability in demanding industrial hydraulic applications. The ‘D’ spool configuration provides a float center position, where work ports A and B are connected to the tank while the pressure port P is blocked.

FAQ

What is the significance of the ‘NG10’ size designation?

NG10 refers to the nominal size of the valve’s mounting interface, conforming to CETOP 5 and ISO 4401 standards. This ensures interchangeability with other NG10 standard valves and subplates, specifying a port pattern and flow capacity suitable for medium-sized hydraulic applications.

Can the 230V AC solenoid coil be replaced with a different voltage, like 24V DC?

Yes, the solenoid coil on this valve is typically modular. You can replace the CW230N9K4 coil with a compatible Rexroth DC coil (e.g., CG24N9K4 for 24V DC), provided the valve body’s actuator pin is compatible. Always consult the datasheet to ensure proper fit and function.

What does the spool symbol ‘D’ indicate about the valve’s function in its center position?

The ‘D’ spool configuration for this 4/3-way valve means it has a float or tandem center. In the neutral, non-actuated position, the pressure port (P) is blocked, while the work ports (A and B) are connected to the tank port (T). This allows the actuator, such as a hydraulic cylinder, to ‘float’ or be moved manually.
