Product details

Hydraulic Valve Solenoid Coilis a key electrical component in hydraulic systems that controls the operation of hydraulic valves. Its core function is to convert electrical energy into mechanical energy to drive the valve spool, enabling the opening/closing or directional switching of hydraulic oil circuits. Below is a detailed introduction:

I. Core Functions and Working Principles

1. Functions

• Converts electrical energy into mechanical energy to drive the spool of hydraulic valves (e.g., directional control valves, pressure control valves, flow control valves).

• Enables automated operation of hydraulic systems (e.g., directional changes, pressure regulation, flow control) by controlling coil energization/de-energization.

2. Working Principles

• When the coil is energized, it generates an electromagnetic field that attracts the iron core (plunger), moving the valve spool to alter its position and control hydraulic oil flow or pressure.

• Upon de-energization, a spring resets the spool to its original position.

II. Key Characteristics and Parameters

1. Voltage Types

• Supports multiple voltage inputs, including DC (12V, 24V) and AC (110V, 220V), to suit diverse industrial applications.

2. Protection Ratings and Durability

• Protection Rating: Premium models achieve IP67, offering dustproof and waterproof capabilities for harsh environments (e.g., humid or dusty settings).

• Lifespan: High-durability models withstand over 50,000 operational cycles, meeting frequent-use demands.

3. Structure and Installation

• Hollow Cylindrical Design: Facilitates direct integration into standard valve sockets, simplifying installation.

• Three-Terminal Electrical Connection: Provides more stable connectivity than two-terminal designs, ensuring reliable signal transmission.

4. Certifications and Standards

• CE-certified to comply with international safety regulations, ensuring safe operation.

III. Typical Applications

1. Industrial Automation Equipment

• Controls hydraulic cylinder extension/retraction and rotation in robotic arms, press machines, and injection molding machines for automated operations.

2. Construction Machinery

• Drives valve spools in excavators and cranes to enable precise movements (e.g., bucket lifting, boom rotation).

3. Fluid Control Systems

• Regulates pressure, flow, or direction in hydraulic systems, such as pressure control valves in hydraulic presses and die-casting machines.

IV. Selection Guidelines

1. Voltage Compatibility

• Choose DC or AC coils based on equipment power supply type, ensuring voltage matching (e.g., 24V DC or 220V AC).

2. Protection Rating Requirements

• Prioritize IP67-rated coils for humid or dusty environments; IP65 or lower may suffice for standard settings.

3. Lifespan and Load Capacity

• Opt for high-cycle models (e.g., 50,000+ cycles) for frequent-use scenarios (e.g., automated production lines).

4. Installation Compatibility

• Verify coil dimensions align with hydraulic valve sockets to avoid installation issues.
