If a circuit has to be limited to 200 bar and unloaded electrically at the same time, this pilot-operated poppet valve in size 32 does both. It discharges up to 650 l/min and weighs 6.3 kg. Adjustment sits on the internal hexagon under the protective cap.

Frequently Bought Together

The setting range runs from 4 to 200 bar, covering power units that work well below the 350 bar limit of the valve. Up to 650 l/min discharges across the subplate interface to ISO 6264-10-17, since the valve belongs to size 32. Adjustment happens on the internal hexagon under the protective cap and solenoid actuation switches the circuit in two positions.

Benefits

  • Setting range of 4 to 200 bar, maximum operating pressure 350 bar
  • Flow up to 650 l/min across the subplate interface to ISO 6264-10-17
  • Pilot-operated poppet design keeps leakage limited in the closed position
  • Internal hexagon with protective cap, the chosen value stays covered
  • Solenoid actuation at 24 VDC in two switching positions, 3-pole connector (2 + PE) to EN 175301-803
  • Mass 6.3 kg in size 32, NBR seals for HL hydraulic fluid

Application

Its usual place is the pump outlet of a power unit whose loads run at 200 bar or less. Solenoid actuation unloads the circuit from the control system without touching the pressure setting. Size 32 matches pumps delivering up to 650 l/min.
