4WE-4WEH valves catalogue

Product catalog summary
Overview: This document provides comprehensive technical specifications and operational guidelines for 4WE and 4WEH directional valves, which are solenoid-operated and used in hydraulic systems. These valves are available in sizes 6 and 10, with various configurations to suit different applications.
Specifications:
  • Sizes: 6 and 10
  • Component Series: 6X/3X
  • Maximum Operating Pressure: 35 MPa
  • Maximum Flow: 120 L/min
  • Coil Rotation: 90°
  • Voltage Compliance: CE marking for voltages >50VAC or >75VDC
Model Code Explanation: The model code specifies features such as nominal size, operation type, series, return mode, solenoid type, input voltage, hand override, electrical connections, throttle position and diameter, and seal material.
Function Description: The valves use solenoid power to move a control spool within the housing, allowing fluid flow between ports. Return types include spring return, without spring return, and orientation organ type, affecting spool return when de-energized.
Technical Data:
  • Weight: Varies with solenoid configuration
  • Ambient Temperature: -30 to 50°C
  • Flow Capacity: Up to 80 L/min for size 6 and up to 120 L/min for size 10
  • Pressure Fluid: Compatible with NBR and FKM seals, suitable for various oils and biodegradable fluids
  • Electrical Specifications: Available in DC and AC, with specific voltage tolerances and power consumption details
Symbols and Flow Directions: Includes symbols representing different spool configurations and their flow directions, critical for understanding valve operation in specific applications.
Characteristic Curves: Graphs illustrate the pressure differential against flow rates for different spool types, aiding in valve configuration selection based on system requirements.
Shifting Power Limits: Provided for different solenoid types (DC and AC) and frequencies (50Hz and 60Hz), with graphs and tables indicating flow in L/min against operating pressure in MPa.
Installation Dimensions: Dimensions are provided for both AC and DC plug-in connection types, with and without lamp central connection, including total length, width, height, and coil take-out measurements for nominal sizes 6 and 10.
Subplate Installation Dimensions: Follow the porting pattern to ISO 4401 standards, with detailed measurements for hole dimensions with a tolerance of ±0.1.
Directional Spool Valves: Describes pilot-operated directional spool valves with hydraulic or electro-hydraulic actuation, available in sizes 10 to 25, featuring subplate mounting, wet-pin solenoids, spring or pressure centering, and pilot throttling regulators.
Model Code: Provides a detailed breakdown of the coding system used to specify different valve configurations, including pressure ratings, types of operation, spool return options, series, pilot valve spool return, input voltage, and additional features like shifting time adjustment and throttle position.
Symbols and Spool Returns: Includes symbols for various valve configurations and explains spool return mechanisms, including spring and hydraulic returns, noting that certain codes apply only to specific sizes and configurations.
