Product details

Core Functions of Electromagnetic Unloading Valves:

These valves regulate and release system pressure via electromagnetic control, with typical applications including:

• Pressure Protection: When system pressure exceeds the set value, the solenoid valve activates, diverting excess hydraulic fluid back to the tank to prevent equipment overload damage.

• Remote Control: Enables automated pressure management through electrical signal-controlled valve operation.

• Energy Efficiency: Reduces system pressure during idle or low-load conditions to minimize energy consumption.

Structure and Working Principle (General Reference):

• Electromagnetic Control Section: Comprises an electromagnet, push rod, and valve spool. When energized, the electromagnet generates magnetic force to move the spool, altering oil circuit connectivity.

• Hydraulic Section: Includes inlet, outlet, and unloading ports. Spool movement switches between high-pressure and unloading circuits.

• Spring Return Mechanism: Upon de-energization, a spring resets the spool to its original position, restoring system pressure.

Application Fields:

Electromagnetic unloading valves are widely used in hydraulic systems, such as:

• Construction Machinery: Pressure control in excavators and loaders.

• Industrial Equipment: Pressure protection and energy-saving operation in injection molding and die-casting machines.

• Automated Production Lines: Precision pressure control for assembly equipment.

Selection and Usage Considerations:

• Parameter Matching: Select models based on system operating pressure, flow rate, and port size compatibility.

• Environmental Adaptability: Account for operating temperature and fluid cleanliness to ensure valve longevity.

• Maintenance: Regularly inspect solenoid coil insulation and spool sealing to prevent leakage.
