Data sheet WE6AH

Product catalog summary
Specifications:
The document outlines the specifications for directional control valves, nominal size 6, type WE 6 AH. Key specifications include a maximum pressure of 320 bar, a maximum flow rate of 80 l/min, and installation dimensions according to DIN 24340 and ISO 4401. The valves are designed for use with mineral oil and have a viscosity range of 20-400 mm²/s. The temperature range is -30 to +80°C for NBR seals and -20 to +80°C for Viton seals. The contamination level is ISO 4406 class 21/18/15.
Functional Description:
The valve consists of a valve body, a 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 shift the spool to direct flow from P to A or B. Solenoids are DC, with rectifiers for AC supply. Manual override is available for power failures. The valve body is phosphate coated, and solenoids are zinc coated.
Ordering Code:
Valves come with standard connectors and manual overrides unless specified otherwise. Special functions and additional options are available upon request.
General Characteristics:
Mounting is optional, with a subplate body according to ISO 4401. The maximum operating pressure is 320 bar for Ports P, A, B, and 210 bar for Port T. The maximum flow is 80 l/min.
Electrical Characteristics:
The maximum switching frequency is 15000/h, with a voltage tolerance of ±10%. The protection type is IP 65, and the duty cycle is 100%.
Special Functions:
Includes manual overrides with closed nut, detent assembly, or rubber boot for protection. There is a switching time delay with venting through a bleed screw and position control with sensor characteristics of 24 V DC, max pressure resistance of 50 bar, and a switching frequency of 1000 Hz.
Dimensions:
Valves are delivered with bolts and O-rings. Solenoid and manual override configurations are detailed.
Procedures:
For valves with two solenoids, power down one solenoid before powering up the other. The switching time for valves with spool type R2A should not be shorter than 60 ms. For spool type E2B, the T-port should be connected directly to the tank if the operating pressure exceeds 210 bar.
Standards and Recommendations:
Installation dimensions follow DIN 24 340-A6 standards. The document advises consulting the manufacturer for operations differing from the provided data. It emphasizes that the technical information is descriptive and not legally binding as guaranteed product properties.
Key Data from Diagrams:
Diagrams indicate signal states for solenoids and sensors, as well as installation dimensions. Key measurements and configurations are provided for proper installation and operation.
Additional Information:
The document highlights the company's commitment to being an innovative, competent, flexible, and quality-oriented system partner for the industry.
