4WE6F60/AW220N9Z5L

Direct drop-in replacement for Bosch Rexroth 4WE6 / 3WE6 series (WE6 ... /CG24N9Z5L and AW220N9Z5L coil variants). Same ISO 4401-03 mounting, no manifold modification required.

Model 4WE6F60/AW220N9Z5L is a wet-armature solenoid directional valve in the 4WE6 family, delivering a direct drop-in fit for Bosch Rexroth WE6 / 3WE6 units on the ISO 4401-03 (Cetop 3, NG6) mounting surface. The spool design follows the standard Rexroth function dictionary - E (all ports closed), G (P-T open), H (P-A/B-T), J, L, M, U, F, D, W, C and Y variants are available across the series - so the exact circuit logic of your existing machine is preserved with zero logic changes. Wet solenoid construction keeps the coil immersed in hydraulic oil for superior heat dissipation, smooth switching and a design service life beyond 8 years.

4WE6F60/AW220N9Z5L mounts directly onto any ISO 4401-03 subplate or manifold block without modification. The solenoid features a Z5L DIN 43650 connector with an integrated indicator light, rated IP65 for dust and oil-mist environments. Coil voltage options are DC 12/24 V and AC 110/220 V; an N9 manual override button is standard, allowing manual spool shifting for commissioning and fault diagnosis even when power is off. Working fluid is mineral oil (HL/HLP) per DIN 51524, with max T-port back pressure of 16 MPa.

Every 4WE6F60/AW220N9Z5L valve is 100% factory-tested before shipment - electrical function, internal leakage and peak pressure up to 31.5 MPa - with test records archived by batch for full traceability. Products are Intertek-certified, backed by a 1-year replacement warranty and 8-year design service life. Bodies are CNC-machined from high-grade cast iron with a tolerance of +/- 0.005 mm, and standard orders ship from Ningbo Port within 7 working days with a 1-piece MOQ.

4WE6F60/AW220N9Z5L suits high-cycle industrial circuits such as hydraulic press ram control, CNC machine tool spindle and tool-changer switching, and automated production line actuator logic. Its 31.5 MPa rating covers the vast majority of stationary and mobile machinery, and the wet solenoid design delivers quiet, repeatable shifting in continuous-duty applications.
