[PDF] electro hydraulic valve system

  • What is an electro-hydraulic valve?

    Electrohydraulic servo valves may consist of one or more stages. A single-stage servo valve uses a torque motor to directly position a spool valve.
    Single-stage servo valves suffer from limitations in flow capability and stability due to torque motor power requirements.

  • What is the use of electro-hydraulic system?

    Electro-hydraulic systems can be used in robust robotics systems that have to carry heavier loads efficiently.
    Electrical drives have proven to be reliable and easy to control, but they may have problems when it comes to holding a position under load for a long period of time.

  • What is the use of electro-hydraulic system?

    High power density, easy motion control, high reliability and sturdiness, possibility of implementing customized solutions, excellent resistance to vibrations and capability of absorbing impulsive loads and, finally, simple thermal exchange management.
