    Hydraulic Solenoid Valve

    A Hydraulic Solenoid Valve is an electrically operated valve used to control the direction, flow, or pressure of hydraulic oil in a hydraulic system. It replaces manual operation with automatic or remote control.

    Working Principle

    • An electrical signal energizes the solenoid coil
    • The coil creates a magnetic field
    • This moves a spool or poppet
    • Hydraulic oil flow is started, stopped, or redirected
    • When power is removed, the valve returns to its original position by spring force.

    Main Components

    • Solenoid coil
    • Valve body
    • Spool / Poppet
    • Return spring
    • Electrical connector
    • Seals

    Common Types

    1. Directional Control Valves

    • 2/2, 3/2, 4/2, 4/3 valves
    • Used for cylinder or motor direction control

    2. Normally Open (NO)

    • Oil flows when power is OFF

    3. Normally Closed (NC)

    • Oil flows when power is ON

    4. Single Solenoid Valve

    • Spring return

    5. Double Solenoid Valve

    • Electrical shifting both directions

    Voltage Options

    • 12 V DC
    • 24 V DC (most common in hydraulic systems)
    • 110 V AC
    • 230 V AC

    Advantages

    • Fast and precise control
    • Remote operation
    • Reduced manual effort
    • Easy automation integration

    Applications

    • Hydraulic power packs
    • Industrial machines
    • Press machines
    • Injection molding machines
    • Material handling equipment
    • Mobile hydraulics (tippers, loaders)

    Selection Parameters

    • Operating pressure (bar)
    • Flow rate (LPM)
    • Voltage & current
    • Valve type (4/2, 4/3, etc.)
    • Port size (NG6, NG10, BSP, CETOP)
    • Oil type & temperature
