Form ID is required.
Category: Tag:

The servo valves offer a direct drive with a permanent magnet linear motor, which moves the valve spool directly and eliminates the need for pilot oil. They are available in nominal sizes 06 in accordance with ISO 4401.

The servo valves were developed with the most demanding customer requirements in mind and are characterized by high functional flexibility, pressure-independent dynamics, high actuating force and low power consumption.

Features:

  • Directly driven by linear force motor: No pilot flow required
  • Linear force motor with high force range (improves operating limits): No flow limitations
  • Directly driven design: Pressure-independent dynamic performance
  • Low current consumption at and near hydraulic null
  • Spool is in spring-centered position at loss of power supply: Actuator stops

Application

find use in various industrial applications, including:

  • Motion control with the highest performance.
  • Used for turbine for the power station
