Product Description
LIC Hydraulic’s WANDFLUH AH Series manual spool valves represent the pinnacle of Swiss precision in hydraulic control. This series (NG6 / CETOP 3), featuring models such as AH4D62A-R, AH4Z62A/R, and AH4D101A/F, is engineered for applications demanding extreme reliability and low leakage. Known for their distinct tactile feedback and high-pressure capability (up to 350 bar), these valves are ideal for both industrial and mobile applications. We guarantee 100% Drop-in Interchangeability with original Wandfluh units. Every valve undergoes 100% high-pressure load testing to ensure laboratory-grade performance in demanding environments like offshore, explosion-proof zones, and heavy manufacturing.
Technical Specifications
Series ID: AH4 Series (Hand Operated)
Nominal Size: NG6 / CETOP 03
Max Operating Pressure: 350 bar (35 MPa / 5075 PSI)
Max Flow Rate: Up to 80 L/min
Operation Type: Manual Lever (Spring Return or Detented)
Spool Functions: D (3-position/4-way), Z (2-position/4-way), etc.
Seal Options: NBR or Viton (FKM) for high-temperature resilience
Finish: Phosphated valve body with corrosion-resistant lever assembly
Key Technical Advantages
Swiss Precision Spool Fit: The clearance between the spool and the housing is ground to micron tolerances, providing world-class low-leakage performance at 350 bar, ensuring the actuator stays in position.
Versatile Detent/Spring Options: The “R” suffix indicates a detent mechanism that holds the lever in position, while spring-return models provide a fail-safe return to neutral, catering to diverse safety and operational requirements.
Compact & Robust Build: The compact design allows for dense manifold integration. High-quality surface treatments prevent mechanical seizing, even in humid or salty environments.
Ergonomic Feedback: The optimized leverage ratio ensures a clear mechanical “click” and smooth transition, allowing operators to perform precise manual flow metering and control.
Application Areas
Mobile Machinery: Auxiliary circuits in excavators, stabilizer control for truck cranes, and manual control consoles for specialized vehicles.
Industrial Presses: Small hydraulic punches, mold adjustment mechanisms, and lab testing equipment.
Emergency Systems: Critical manual overrides and hydraulic systems in power-free or hazardous zones.
Expert Maintenance Tips
Center Function Verification: The AH4D series offers numerous spool codes (e.g., 62, 101), defining how ports P, T, A, and B interact in neutral. Verify the original configuration to avoid system pressure spikes or drifting.
Lever Orientation: The lever assembly can be mounted in various angles. Ensure the mounting position allows for a full range of motion and prevents accidental actuation.
Bellows Maintenance: Inspect the rubber bellows at the base of the lever regularly. In dusty environments, a torn bellow can allow contaminants to enter the precision seal area, leading to spool friction.
