Product catalog summary
Directional Control Valves Nominal Size 6 (WE 6 AH)
Specifications:
  • Pressure: Up to 320 bar
  • Flow: Up to 80 l/min
  • Installation dimensions: According to DIN 24340 and ISO 4401
Functional Description:

The WE 6 AH valve includes a valve body, control spool with centering springs, and solenoids. Three-position valves have two solenoids and springs, while two-position valves may have one solenoid with a return spring or two solenoids with a detent. Solenoids direct flow from P to A or B and are DC with rectifiers for AC supply. Manual override is available for power failures.

General Characteristics:
  • Mounting: Optional, subplate body according to ISO 4401, CETOP 03
  • Max Operating Pressure: 320 bar for ports P, A, B; 210 bar for port T
  • Max Flow: 80 l/min
  • Fluid: Mineral oil, viscosity range 20-400 mm²/s
  • Temperature Range: -30 to +80°C for NBR seals, -20 to +80°C for Viton seals
  • Contamination Level: ISO 4406 class 21/18/15
Electrical Characteristics:
  • Max Switching Frequency: 15000/h
  • Voltage Tolerance: ±10%
  • Protection Type: IP 65
Ordering Code:

Valves come with standard connectors and manual overrides. Special functions like switching time delay and position control are available upon request.

Special Functions:
  • Manual Overrides: Available with closed nut, detent assembly, or rubber boot for protection.
  • Switching Time Delay: Achieved through an orifice in the armature, requiring careful venting.
  • Position Control: Sensor characteristics include a rated voltage of 24 V DC and a switching frequency of 1000 Hz.
Diagrams and Symbols:

Details various spool types and configurations with symbols indicating positions and transitions.

Procedures:

For valves with two solenoids, power down one solenoid before powering up the other. The switching time for spool type R2A should not be shorter than 60 ms.

Standards and Recommendations:

For spool type E2B, if operating pressure exceeds 210 bar, connect the T-port directly to the tank. Consult the manufacturer for operations differing from the provided data.

Warnings:

The technical information is descriptive and not guaranteed product properties. Proper installation requires a specified surface finish of the interface.

Additional Information:

Directions to the company's location are provided, highlighting their role as an innovative system partner, emphasizing competence, flexibility, and quality orientation.
