4WE6 Solenoid Valve | 4WE6D | 4WE6J | 4WE6E | 24V DC 240V AC | NG6 CETOP 3 Hydraulic Reversing Valve

4WE6-20 Series Industrial Solenoid Directional Valves

Product Overview: The 4WE6 series is a range of compact, direct-operated solenoid directional control valves, fully compliant with ISO 4401-03 (NG6 / CETOP 3) mounting standards. Utilizing wet-pin solenoid technology, the armature operates within hydraulic fluid, ensuring smooth switching while eliminating the risk of oil leakage at dynamic seals. The 20 design series optimizes production efficiency without compromising performance, making it the ideal choice for industrial automation lines, machine tools, and light-duty hydraulic power units.

Featured models include: 4WE-6D/DE-W240-20 and 4WE-6-J/E-G24-20.

Key Technical Advantages:

• Classic 20 Series Design: Robust and field-proven, offering high interchangeability for seamless direct replacement of mainstream global brands.

• Rapid Response Wet-Pin Actuation: Available in G24 (24V DC) and W240 (240V AC) variants, supporting 100% ED (Continuous Duty) with superior heat dissipation.

• Versatile Logic Options: Features core spool logics including D (2-pos 4-way), E (3-pos 4-way, closed center), and J (Unloading center) to meet diverse hydraulic sequence requirements.

• Ruggedized Protection: The fully encapsulated coils provide excellent vibration and moisture resistance, ensuring reliable long-term operation in harsh industrial environments.
