Model Comparison

Series 252

  • Two-stage, four-way servovalves
  • Low to medium flow applications (3.8 - 227 lpm or 1 - 60 gpm)
  • Typical applications: hydraulic power control and regulation in fatigue test systems, simulators, servohydraulic process controls and industrial controls

Series 256

  • Electrohydraulic three-stage servovalves
  • High-flow, four-way spool valve and smaller two-stage pilot  valve
  • Typical applications: position, load or velocity control of larger hydraulic actuators in highly dynamic applications, as well as pressure control in a dynamic pressurization system

Series 257

  • Two-stage, four-way servovalves with electrodynamic pilot stage
  • Typical applications: high-flow closed-loop servohydraulic applications that require extremely high precision, and high-frequency applications
