Pressure Relief Valve DBW 30 B2-5X/315-6EG12N9K4/12 - Bosch Rexroth R978918704

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

Applications

This version goes into power units and special machinery whose control system is built on 12 VDC. In a fault the full delivery flow of up to 650 l/min is passed away. The solenoid lets the circuit run pressureless during breaks.
