What is the function of 4WE10 single-head solenoid reversing valve?

The 4WE10 single-head electromagnetic directional valve is a key control component widely used in industrial hydraulic systems. Its core function is to control the flow direction, pressure and flow rate of hydraulic oil through electromagnetic force to achieve automated movement and operation of mechanical components. The following is an analysis from three dimensions: functional principles, application scenarios, and technical advantages:

1. Functional principle: combination of electromagnetic drive and hydraulic control

The 4WE10 single-head solenoid directional valve adopts the design of solenoid coil driven directional spool valve. Its working principle is based on the synergy of electromagnetic force and hydraulic force:

Energized state: When the solenoid coil is energized, a magnetic field is generated, which attracts the valve core to move and changes the hydraulic oil path. For example, in hydraulic cylinder control, movement of the spool allows hydraulic oil to enter one side of the cylinder, pushing the piston into motion.

Power-off state: the electromagnetic force disappears, the spring or hydraulic pressure resets the valve core, and the flow direction of the hydraulic oil changes or is cut off. This design enables accurate start, stop and direction switching of the hydraulic system.

Structural features: Some models (such as 4WE10D3X) support 90° rotation of the electromagnetic coil for easy installation; the electrical connection can be single-channel or centered, adapting to different control needs.

2. Application scenarios: covering the automation needs of multiple industries

4WE10 single-head solenoid directional valve is widely used in the following fields due to its high pressure and large flow characteristics:

Construction machinery:

Road rollers and excavators: drive the vibrating wheel or traveling motor by switching the direction of the hydraulic oil.

Concrete pump truck: Control the movement of the boom hydraulic cylinder to achieve accurate distribution.

Industrial equipment:

Injection molding machine: adjust the hydraulic pressure and speed of mold closing, injection and other actions.

Machine tools: Control the coolant circulation system to ensure stable cutting flow.

Energy and ships:

Wind power generation: adjust the blade angle of the pitch system to optimize power generation efficiency.

Ship propulsion: manages hydraulic steering gear to achieve steering control.

Special environment:

Petrochemical industry: The explosion-proof 4WE10 series can control the on-off of corrosive media and complies with ATEX standards.

Iron and Steel Metallurgy: Control of mold positioning and cooling water flow in continuous casting lines.

3. Technical advantages: balance of high performance and flexibility

High pressure and large flow design:

The nominal pressure can reach 32MPa and the flow rate can reach 320L/min, which is suitable for the needs of heavy-duty machinery.

The valve core has a larger diameter and is more efficient than the 4WE6 series, reducing energy loss.

Flexible control methods:

Supports manual emergency switching to ensure equipment safety in case of power outage or failure.

Optional non-contact position detection function enables accurate control and status monitoring.

Adapt to complex working conditions:

Some models (such as 4WE10H wet solenoid valve) can work in vacuum, negative pressure or zero pressure difference environments.

The mounting surface complies with DIN 24340 Type A and ISO 4401 standards, with strong compatibility.

Maintenance convenience:

The electromagnetic coil can be replaced individually, reducing maintenance costs.

Provides PWM connector options to improve energy efficiency.
