1. Product Basics & Model Interpretation
Q1: What type of valve is the 4WE6 series, and how does it work?
A1: The 4WE6 series is a 4-way solenoid-operated directional control valve, a core component in hydraulic systems. It belongs to the direct-acting spool valve category. Its working principle is as follows: When the solenoid coil is energized, it generates a magnetic force that pushes the spool to move axially within the valve bore. This movement changes the connection between the valve’s oil ports (P, T, A, B), thereby redirecting the flow of hydraulic oil. Ultimately, this controls the start, stop, and movement direction of hydraulic actuators (e.g., cylinders, hydraulic motors).
Q2: What do the codes in a typical 4WE6 model (e.g., 4WE6E6X/EG24N9K4) represent?
A2: 4WE6 model codes follow international hydraulic valve naming conventions, with each segment indicating key specifications:
- 4: Number of oil passages (4-way valve, with 4 main ports: P = pressure oil inlet, T = return oil outlet, A/B = working ports connected to actuators).
- WE: Valve type (W = directional control valve; E = solenoid-operated; combined, "WE" denotes a solenoid-driven directional control valve).
- 6: Nominal size (corresponds to NG6, with a nominal port diameter of 6 mm).
- E: Spool function (indicates the flow path configuration of the spool in different positions; common functions include D, Y, O, etc.).
- 6X: Series identifier (used by manufacturers to distinguish product generations or design variations).
- EG24: Solenoid voltage (E = standard solenoid; G24 = DC 24V; other common options: G12 = DC 12V, W220 = AC 220V).
- N9: Connector type (specifies the electrical connector model and protection level, e.g., N9 for standard industrial plugs).
- K4: Auxiliary function (K4 = manual emergency operation; allows manual spool shifting if the solenoid fails).
