Working Mechanism of the 4WE6 Electromagnetic Directional Valve
Valve Operation Explanation
The 4WE6 Electromagnetic Directional Valve by Bosch Rexroth changes the direction of hydraulic fluid flow in a system using electromagnetic principles. It enhances efficiency and accuracy in hydraulic operations.
Electromagnetic solenoid is a key part of this valve. Passing an electric current through the solenoid creates a magnetic field that activates the valve spool. The spool is an internal component that opens or closes different passages within the valve to control fluid flow direction.
To understand how the 4WE6 valve works, follow this step-by-step guide:
- Activation of Electric Signal: An electrical signal energizes the solenoid. This signal may be supplied by an automatic switch or control system.
- Creation of Magnetic Field: An energized coil produces a magnetic field, the strength of which depends on the amount of electric current flowing through the coil’s windings.
- Movement Of Spools: The magnetic field moves the spools inside the valve body, changing flow paths within the valve. This allows fluids to pass through some ports while blocking others.
- Directional Flow Control: Different spool positions supply oil under pressure to various regions, driving cylinders and motors in hydraulic actuation systems.
- Deactivation Plus Resetting: When the solenoid is de-energized, it loses its magnetizing ability. Springs or other mechanisms automatically push the spools back to their resting positions, blocking all channels as before the command arrived.
This process, controlled by the solenoid, allows the 4WE6 valve to make fast and reliable changes in fluid direction, making it suitable for applications requiring quick and accurate fluid control.
Major Components Involved
Several main parts interact during the operation of the 4WE6 Electromagnetic Directional Valve:
- Coil: This component, made of copper wire wound around a core, generates a magnetic field when energized.
- Spools: These components within the valve body direct the flow paths of hydraulic fluid.
- Body: The housing for various internal elements, providing necessary flow paths.
- Spring: Return springs push movable parts back to their original positions when power supply ceases, resetting the valve to its default condition.
- Sealing Devices: High-quality seals made from NBR/FKM materials prevent leakages and enhance reliability.
- Electric Connector: Facilitates connection between controlling devices and solenoids, ensuring uninterrupted transmission of electrical inputs.
- Ports: Openings on the valve body through which fluids enter or leave, depending on applied pressure differentials.
These components work together to ensure the Bosch Rexroth 4WE6 Electromagnetic Directional Valve operates efficiently and reliably, controlling hydraulic fluid flow and enhancing system performance across various industries.
