REXROTH 4WE10HA33/CW230N9K4/V R900973907

Rexroth 4/3-Way Hydraulic Directional Valve NG10 230V AC Description A robust and reliable direct-operated directional spool valve from Bosch Rexroth, model 4WE 10 HA33/CW230N9K4/V. This NG10 (CETOP 5) valve is designed for controlling the start, stop, and direction of fluid flow in a hydraulic system. It features a 230V AC solenoid for actuation and an ‘H’ type spool, which interconnects all ports in the spring-centered neutral position. This makes it suitable for applications requiring pressure relief or circulation in the idle state. Specifications Manufacturer: Bosch Rexroth Type: 4WE 10 HA33/CW230N9K4/V Material Number: R900973907 Valve Type: 4/3-Way Directional Spool Valve Operation: Direct Solenoid Actuated Size: NG10 / CETOP 5 Spool Symbol: H (All ports interconnected in neutral position) Actuation Voltage: 230V AC (50/60 Hz) Electrical Connector: DIN EN 175301-803 (Form A) Seal Material: FKM (Viton) Label Info Manufacturer: Rexroth MNR: R900973907 Model: 4WE 10 HA33/CW230N9K4/V FD: 01124 Application Ideal for use in machine tools, manufacturing equipment, presses, and general industrial hydraulic systems where reliable flow direction control is essential. The ‘H’ spool is often used in circuits with fixed displacement pumps to unload the pump in the neutral position. Country of Origin Made in Germany. CO2 Impact Reusing this component saves an estimated 16.4 kg of CO2, which is equivalent to the emissions of driving a car for 82 kilometers. By choosing a refurbished part, you contribute to a more sustainable industrial environment. Availability This item is a tested, used part in excellent working condition.

In the neutral (de-energized) position, an ‘H’ spool connects all four ports (P, T, A, and B) together. This is often used to unload a fixed-displacement pump to the tank, reducing heat and energy consumption when the actuators are idle. Can I use a different voltage coil with this valve body?Yes, the solenoid coil on this valve (type ‘C’ in CW230N9K4) is detachable. You can replace the 230V AC coil with another compatible Rexroth coil of the same size, for example, a 24V DC coil, to match your system’s control voltage. However, ensure the replacement coil has the correct specifications. What does the ‘/V’ at the end of the type number signify?The ‘/V’ indicates that the valve is fitted with FKM (Fluorocarbon rubber, commonly known as Viton) seals. These seals offer excellent resistance to high temperatures, mineral oils, hydraulic fluids, and many chemicals, making the valve suitable for a wider range of applications and fluids compared to standard NBR seals.
