Product Overview

▔▔

The Bosch Rexroth 4WE6J62 is a high-performance, direct solenoid-operated 4/3 directional spool valve featuring a Series 6X design configuration and a J-type center position. Engineered to regulate the start, stop, and direction of fluid flow, this valve series serves as an industry benchmark for precision industrial and mobile hydraulic control scenarios.

Key Advantages

▔▔

Series + Type + Core Function: Series 6X direct-operated 4/3 directional spool valve with J-center symbol, delivering reliable multi-position hydraulic control, neutral fluid blocking, and smooth actuator shifting.
High-Pressure Capability: Operates reliably up to $350\text{ bar}$ on pressure ports P, A, and B, accommodating demanding industrial duty cycles.
Wet-Pin Solenoid Design: Features oil-immersed DC/AC solenoids with detachable, rotatable coils for effortless field maintenance and superior heat dissipation.
Global Standard Interface: Conforms strictly to ISO 4401-03, DIN 24340 Form A, and CETOP 3 mounting standards for seamless system retrofitting.

Configuration Options

▔▔

Valve Structure: Direct solenoid-operated, 4-way, 3-position directional spool valve with spring return to the center neutral position (J-symbol: P-port blocked, A & B connected to T).
Control & Actuation: High-power wet-pin solenoids with integrated manual override ($N9$) for emergency or setup operation without electrical power.
Rated Flow: Optimized for standard flows up to $80\text{ L/min}$, with optional sandwich plate throttle inserts available for flow limitation in port P.
Interface & Mounting: Subplate mounting configuration adhering to ISO 4401-03-02-0-05 layout, utilizing four mounting bolts.
Electrical Configuration: Available in multiple DC and AC voltage ratings ($24\text{V DC}$, $110\text{V AC}$, $230\text{V AC}$) equipped with K4 plug-in connectors (per EN 175301-803) or terminal box conduit connections.

Key Materials and Components

▔▔

Spool and Sleeve: Precision-ground, hardened alloy steel engineered to maintain minimal internal leakage and resist wear under high-cycle hydraulic operations.
Valve Housing: High-grade ductile iron casting designed to withstand fatigue at maximum operating pressures up to $350\text{ bar}$.
Sealing Materials: Standard Buna-N (NBR) seals optimized for mineral oil compatibility; optional Fluoroelastomer (FKM/Viton) seals available for synthetic or high-temperature fluid requirements.
Solenoid Coil Enclosure: Copper winding protected by high-temperature insulation and sealed within a metallic shell for oil immersion cooling.

Packaging and Transport Protection

▔▔

Industrial Packaging: Individually boxed in heavy-duty corrugated cartons designed to protect external components and electrical pins.
Moisture Protection: Sealed inside anti-corrosion VCI (Volatile Corrosion Inhibitor) plastic bags to prevent rust during ocean transit and extended warehouse storage.
Shock & Fixation: Cushioned with high-density molded foam inserts to eliminate shifting and impact damage during shipping.
Batch Packaging: Packed onto reinforced wooden pallets wrapped with stretch film and secured with strapping for bulk industrial distribution.

Applications

▔▔

FAQ

▔▔

Q1: How do I confirm the exact replacement model code for my system? A: Check the nameplate stamped on the valve body to verify the exact part number (e.g., R-number) and spool symbol letter. If the plate is unreadable, measure the port pattern dimensions to confirm NG6 / CETOP 3 compatibility and verify your system voltage.

Q3: What types of hydraulic oils are compatible with this valve? A: The standard NBR seal version is fully compatible with mineral oils conforming to DIN 51524 (HL, HLP). For synthetic or biodegradable fluids (HEES, HEPG), please specify FKM seals.
