4. Advantages of Wet-Type Solenoid Design

Effective Lubrication and Reduced Wear

The oil-immersed structure allows hydraulic fluid to lubricate moving components, helping reduce friction and wear during repeated valve actuation. This design is beneficial for hydraulic equipment that operates frequently or for extended periods.

Improved Thermal Management

Hydraulic fluid helps dissipate heat generated during operation. Under suitable working conditions, this can support thermal stability and dependable performance during continuous or repetitive operating cycles.

Consistent Electromagnetic Actuation

An optimized magnetic circuit and precision-manufactured components help provide stable magnetic output for dependable valve switching. Consistent actuation supports the normal operation of hydraulic circuits and connected machinery.

Support for Long-Term Operation

The combination of lubrication, cooling, and durable coil construction helps reduce component stress during service. Actual service life depends on operating voltage, switching frequency, hydraulic fluid conditions, temperature, and system maintenance.

Integration into Industrial Hydraulic Equipment

The MFJ12 Series is designed for use with compatible hydraulic valves and equipment. Confirming model dimensions, electrical parameters, and valve interface requirements before installation helps ensure proper system integration.

MFJ12-27: Select this model when its verified dimensions, electrical characteristics, and valve interface meet the requirements of your hydraulic assembly.

MFJ12-54: Consider this model when its verified configuration matches the intended valve and equipment design.

The model numbers alone do not establish rated voltage, dimensions, force, stroke, or interchangeability. Please provide your valve model or technical drawing so the appropriate configuration can be checked before purchase.

8. Installation and Maintenance Recommendations

For reliable operation, consider the following points when integrating a wet-type solenoid into a hydraulic system:

• Verify the rated voltage and electrical supply before energizing the coil.

• Confirm mounting dimensions and the mechanical interface with the target valve.

• Ensure the solenoid is compatible with the hydraulic fluid and operating conditions.

• Maintain suitable hydraulic fluid cleanliness to help prevent contamination-related wear.

• Check wiring, connectors, and insulation according to the equipment requirements.

• Operate within the manufacturer's specified temperature, duty cycle, and electrical limits.

• Inspect the assembly periodically for abnormal heating, leakage, or changes in actuation performance.

Installation and maintenance should follow the confirmed technical documentation for the selected model and hydraulic valve.
