Solenoid Coils for Hydraulic

hydraulic Solenoid Coils play a crucial role in the operation of hydraulic distributors and solenoid valves. They are essential for technicians, industrial workers, and individuals working with hydraulic systems, whether in agriculture, industry, or material handling.

What is a Hydraulic Solenoid ?

Definition

A hydraulic valve coil, also known as an solenoid coil, is an electromagnetic device that activates a solenoid valve or hydraulic distributor. It converts electrical energy into mechanical movement through a magnetic field, allowing the opening or closing of hydraulic circuits. Our hydraulic solenoids are designed for all electrical distributors from the BOSCH REXROTH OIL CONTROL group, as well as for EDI SYSTEM, LC OLEODINAMICA, OIL SISTEM solenoids. Our range is so vast that we can also integrate solenoids for distributors from brands like HYDAC, NEM, Valvoil, ARON, HYDRAPP, and other hydraulic distributor brands.

Operation

The operation is based on the principle of electromagnetism. When current passes through the hydraulic solenoid coil windings, a magnetic field is generated, attracting the metal core. This movement activates or deactivates the hydraulic valve mechanism, regulating the flow of hydraulic fluid.

Types of Solenoid Coil

hydraulic coils are primarily distinguished by their power supply type and specific use. Here are the three main categories:

DC solenoid valve (Direct Current)

• Used in applications requiring precise control.
• Operates on voltages like 12V or 24V DC.
• Ideal for applications requiring prolonged activation.
• Energy-efficient and often used in fixed industrial systems.

AC solenoid valve (Alternating Current)

• Preferred in industrial environments for their robustness.
• Designed for alternating voltages such as 24V AC, 230V AC.
• Ideal for short, frequent cycles.
• Often used in environments where AC power is available.

RAC solenoid valve (Rectified Current)

• Combine the advantages of AC and DC solenoids.
• Provide stable performance with rectified AC power.

Applications of Hydraulic Valve Coil

hydraulic Solenoid coils are used in a wide range of sectors:

• Industry and Manufacturing

  • Control of solenoid valves on production lines.
  • Used in hydraulic presses and cooling systems.
  • Example: Hydraulic systems for industrial presses, assembly lines, pneumatic systems.

• Agriculture

  • Control of hydraulic equipment such as sprayers or harvesting machinery.
  • Example: Agricultural machines like harvesters, planting or harvesting machines equipped with hydraulic circuits.

• Construction and Civil Engineering

  • Operate hydraulic cylinders on construction equipment like excavators and cranes.

• Material Handling and Transport

  • Control hydraulic functions of forklifts and lifting platforms.
  • Automation: Industrial robots, automated doors.

In summary, solenoid coils are found wherever precise control of pressurized fluid flow is needed.

Criteria for Selecting a Hydraulic Coil

Choosing the right hydraulic valve coil can seem complex. Here are the main criteria to consider:

1. Voltage and Current Type:

   • Should match the available power supply.
   • Check if your system uses direct current (DC) or alternating current (AC).
   • Identify the required voltage (e.g., 12V, 24V, 230V).

2. Physical Compatibility:

   • Dimensions: Verify the inner diameter of the solenoid, height, and connector size.

3. Operating Environment:

   • Extreme conditions require specific solenoids.
   • Thermal resistance: If the solenoid must operate in hot or cold environments.
   • Protection against dust and liquids: Choose a solenoid with a high IP rating if necessary.

4. Connectors and Wiring:

   • Depends on the environment and application.
   • Ensure the solenoid is equipped with the correct type of connector (DIN, fixed cables, etc.).

Advantages of Hydraulic Solenoid Coils

Strengths:

• Precision and Responsiveness: Hydraulic solenoids allow fast, precise control of hydraulic systems.
• Versatility: They are suitable for a wide range of machines and applications.
• Reliability: Modern solenoids are designed to last, even in demanding environments.

Limitations:

• Overheating: A misfit solenoid or one used beyond its capacity can overheat.
• Environmental Sensitivity: Poor protection against dust or liquids can reduce its lifespan.

Installation and Maintenance

Proper installation and regular maintenance ensure the longevity of solenoid coils. It is crucial to follow the manufacturer's instructions and perform periodic inspections to detect wear or damage. If malfunctioning occurs, check the power supply, the hydraulic coil's condition, and the cleanliness of the hydraulic lines. If the issue persists, consult a specialist.

Installation in 3 Steps

• Preparation:

  • Turn off the power before handling the hydraulic valve coil.
  • Verify that the hydraulic solenoid coil is compatible with your hydraulic system.

• Positioning:

  • Correctly position the solenoid coil on the distributor or solenoid valve.
  • Tighten firmly but without overdoing it to avoid damage.

• Connection:

  • Connect the wiring according to the manufacturer's technical specifications.

Maintenance

• Regular Cleaning: Eliminate dirt or deposits that may reduce efficiency.

• Periodic Checks: Test electrical continuity to detect possible failure.

• Preventive Replacement: Replace the hydraulic coil at the first signs of weakness to avoid service interruptions.
