Frequently Bought Together

The unloading solenoid of a pressure relief valve has to match the control voltage on site. This pilot-operated seat valve in size 32 runs on 12 VDC, covers an adjustment range of 4 to 315 bar and passes up to 650 l/min.

Benefits

  • 12 VDC supply voltage at the unloading solenoid
  • Adjustment range of 4 to 315 bar at a maximum operating pressure of 350 bar
  • 650 l/min relief capacity through the ISO 6264-10-17 interface in size 32
  • Seat valve design, which keeps leakage low in the closed state
  • Internal hexagon with a protective cap, so the setting stays secured
  • 6.3 kg on subplate mounting, NBR seals for HL hydraulic fluid
