The Bosch Rexroth 4WEH is a pilot-operated directional spool valve for the higher flows that direct-operated 4WE valves cannot handle. A small pilot valve shifts a larger main spool, so one valve can control large cylinders and motors at pressures up to 420 bar. Twin Hydraulics Engineering supplies 4WEH valves across Malaysia in sizes NG10 to NG32.
The type code identifies the size, spool symbol, spring or detent arrangement, coil voltage and pilot supply. Please check these against your existing valve or circuit drawing before ordering, since several spool symbols look similar but behave differently in the circuit.
Browse the part numbers in this family, or send us the type code or material number from your nameplate and we will quote the exact valve. Smaller flows are covered by the 4WE 6 and 4WE 10 ranges, and we also supply the matching subplates, solenoid coils and seal kits.
