Product Introduction
The 4WE6G is a direct-operated, 3-position, 4-way solenoid directional control valve with G-type tandem center function. It follows the NG6 (CETOP 03) mounting standard, ensuring wide compatibility with hydraulic manifolds and industrial equipment.
Working Principle: In the neutral (center) position, the G-type spool connects the pressure port (P) to the tank port (T), allowing the pump to unload for energy saving. At the same time, working ports A and B are blocked, maintaining the position of cylinders or motors accurately. When either solenoid is energized, the spool shifts to direct flow from P to A or B.
Core Components: The 4WE6G Tandem Center Valve consists of a precision-machined valve body, hardened and ground G-type spool, wet-type solenoid coils (detachable and replaceable), return springs, and manual override (for emergency operation).
Features & Technical Advantages
The 4WE6G Tandem Center Valve delivers reliable, energy-efficient control through several key design features:
G-Type Tandem Center Function: P→T connection in neutral for pump unloading (energy saving) plus A/B blocked for load holding - two benefits in one valve.
Direct-Operated Design: Fast response - the solenoid moves the spool directly without a pilot stage.
Wet-Type Solenoids: Oil-immersed armature provides cooling, low noise, and long service life. Coils are detachable - replace without oil leakage.
Manual Emergency Override: Concealed manual override (tool-operated) as standard - allows shifting during power failure.
NG6 Standard Mounting: Conforms to ISO 4401 (CETOP 03) - compatible with standard manifolds.

FAQ
Q: What kind of valve is the 4WE6G?
A: The 4WE6G is a direct-operated, three-position, four-way solenoid directional control valve; it features the NG6 (CETOP 03) size, and its mounting surface complies with the ISO 4401 standard.
Q: Can the coil of a wet-type solenoid be replaced separately?
A: Yes. The coil features a detachable design; it can be removed and replaced by simply loosening the retaining nut, without needing to disassemble the valve body or causing any oil leakage. When replacing the coil, ensure that the voltage and power ratings match the original specifications.
Q: Does the 4WE6G feature manual override?
A: The standard configuration includes a concealed manual override that requires a tool to operate. Versions with an exposed manual override or a lockable manual button are also available as options. The manual override allows the valve spool to be shifted temporarily in the event of a power failure or solenoid malfunction, enabling continued equipment operation.
Q: How do you deal with a stuck valve spool?
A: First, check the cleanliness of the hydraulic fluid, then inspect the spool surface for scratches or wear.
Q: What should be done if oil is seeping from the exterior of the valve body?
A: Check if the mounting bolts are loose and retighten them to the specified torque. If the bolts are secure, inspect the oil port seal for signs of aging or damage. Seepage at the mounting surface may require replacing the seal or checking the flatness of the mounting surface.
