Features:

  • 2-stage flow control Mechanical Feedback Valve
  • Nozzle flapper pilot stage for high dynamics, high resolution and low hysteresis
  • "Simulator" spool cut minimizes pressure change and "bump" through the zero flow null position
  • High spool driving forces, rugged design ensures long-life operation
  • Optional integrated abort manifold/end cap to control motion of actuator to home position in the event of an abort signal
  • Optional asymmetric flow ratios matched to actuator cylinder requirements
