Rexroth 4WEH 10 Series Pilot Operated Directional Control Valve

Description

This is a 4WEH 10 series electro-hydraulic directional spool valve from Bosch Rexroth. It is a high-performance, pilot-operated valve designed for controlling the start, stop, and direction of fluid flow in hydraulic systems. The NG10 size allows for high flow rates, making it suitable for demanding industrial applications. This assembly includes the main stage valve and the NG6 pilot valve for complete functionality.

FAQ

What is the function of the pilot valve (4WE 6) on this 4WEH 10 main valve?

Answer

The smaller NG6 (4WE 6) valve is a direct-acting solenoid valve. It uses the system's hydraulic pressure to shift the main spool in the larger NG10 (4WEH 10) valve. This pilot operation allows a small electrical signal to control a very high hydraulic flow and pressure with precision, which would be impossible with a direct-acting solenoid of this size.

What type of hydraulic fluid is recommended for this Rexroth valve?

Answer

These valves are typically designed for use with mineral oil-based hydraulic fluids (HL, HLP) according to DIN 51524. For use with other fluids, such as synthetic esters or water glycols, you must consult the official Bosch Rexroth datasheet to ensure compatibility with the valve's seals and materials.

How can I identify the spool type and its center position function from the type code "J46"?

Answer

The "J" in the type code "J46/..." indicates the spool type. For Rexroth 4WEH valves, a 'J' spool is a 3-position, spring-centered spool. In its neutral (center) position, it typically connects the P (pressure) port to the T (tank) port, while blocking the A and B work ports. This configuration unloads the pump when the valve is not actuated. Always refer to the specific datasheet for R900948924 to confirm the exact flow path diagram for the 'J46' spool.
