Proportional pressure relief valve

NG 6

Max pressure 315bar , Nominal flow 1L/min

  • Direct operated valves for limiting system pressure
  • Adjustable by means of the solenoid current, see performance curve, Technical data and selected valve electronics
  • Pressure limitation to a safe level even with electric failure (solenoid current I > Imax)
  • For subplate attachment, mounting hole configuration to ISO 4401-03-02
  • External trigger electronics with ramps and valve calibration (order separately)
