Rexroth Type 4WMM Manual Directional Valve | 4WMM6 | 4WMM10 | 4WMM16 | Hand Lever Operated Hydraulic Valve

4WMM Series Hand-Lever Operated Directional Control Valves

Product Overview: The 4WMM series consists of direct or pilot-operated directional spool valves actuated via a hand lever, providing the most reliable and intuitive control for hydraulic systems. Covering Size 6 (NG6), Size 10 (NG10), and Size 16 (NG16), the series is fully compliant with ISO 4401 mounting standards. As they require no electrical power, 4WMM valves are the premier choice for mobile machinery, manual presses, marine equipment, and industrial environments with strict explosion-proof requirements.

Featured models include: 4WMM6D53 (including spring return models /F), 4WMM10E3X, 4WMM10Q3X, and high-flow models like 4WMM16G7X/F.

Key Technical Advantages:

• Intuitive Manual Control: The optimized lever mechanism ensures low operating force and precise tactile feedback, allowing operators to accurately manage actuator start, stop, and direction.

• Versatile Reset Options: Available in Spring Return and Detent (Steel Ball Positioning) versions to suit continuous switching hold or automatic reset requirements.

• Extensive Flow Range: Spanning from the compact 4WMM6 (60 L/min) to the heavy-duty 4WMM16 (up to 300 L/min), catering to systems of various power levels.

• Rugged Environmental Durability: Robust cast-iron housing combined with high-performance seals ensures stable operation under high pressures (up to 35 MPa) and harsh outdoor conditions.
