4/3, 4/2 and 3/2 Directional Valve with Wet-pin AC or DC Solenoid

Product catalog summary
Overview: This document outlines the technical specifications and operational guidelines for the Hengli hydraulic directional solenoid valve, Type WE 6...L6X, used to control the start, stop, and direction of flow in hydraulic systems.
Specifications: The valve is a direct-operated directional solenoid valve with a porting pattern compliant with DIN 24 340 form A, ISO 4401, and CETOP-RP 121 H standards. It features wet-pin AC or DC solenoids with a detachable coil, allowing coil changes without opening the pressure-tight chamber. It supports both individual and central electrical connections, with a nominal size of 6, and operates up to 350 bar and 80L/min.
Function and Configurations: The valve includes a housing, one or two solenoids, a control spool, and return springs. In its de-energized state, the control spool is held in a neutral position by return springs. The spool is actuated via wet pin solenoids, with an optional manual override button. Configurations include versions with two spool positions and solenoids with or without detent.
Ordering Code: A detailed ordering code system is provided, specifying options for solenoid types, voltage, manual override, seals, and throttle inserts. Various spool symbols and configurations are available to meet different operational needs.
Technical Data: The valve operates in temperatures from -30 to +50°C with NBR seals and -20 to +50°C with FKM seals. It supports a maximum operating pressure of 350 bar at ports A, B, and P, and 210 bar (DC) or 160 bar (AC) at port T. It is compatible with mineral oil and phosphate ester fluids, with a viscosity range of 2.8 to 500 mm²/s.
Performance Limits: Performance limits are detailed for various solenoid configurations and spool symbols, with characteristic curves provided for flow and pressure differentials.
Unit Dimensions: Detailed dimensions are provided for valves with both DC and AC solenoids, including space requirements for connector and coil removal, and specifications for securing nuts and valve fixing screws.

Hengli hydraulic | Hydraulic components Directional valve | Type WE 6...L6X Type WE valves are solenoid operated directional spool valves. They control the start, stop and direction of flow. The directional control valves consist of housing (1), one or two solenoids (2), the control spool (3), and one or two return springs (4). In the de-energized condition the control spool (3) is held in the neutral or initial position by means of return springs (4) (except for impulse spools). The control spool (3) is actuated via wet pin solenoids (2). To ensure proper operation, care must be taken that the...

Hengli hydraulic | Hydraulic components Performance limits Directional valve | Type WE 6...L6X (Measured at ϑoil =40℃ ±5℃ , using HLP46) The specified switching performance limits are valid with two directions of flow (e.g. from P to A and simultaneous return flow from B to T). Due to the flow forces acting within the valve, the permissible switching performance limit can be significantly lower with only one direction of flow (e.g. from P to A, with port B being closed)! The switching performance limit was determined with the solenoid at operating temperature, at 15 % under-voltage and without...
