Pressure Relief Valve DBW30B2N5X/150-6EG24N9K4E - Bosch Rexroth R901321299

In series machinery the cut-off pressure should stay as commissioned. This pilot-operated pressure relief valve is therefore adjusted from 4 to 150 bar through an internal hexagon under a protective cap and discharges up to 580 l/min through its subplate connection.

Benefits

• Internal hexagon under a protective cap instead of a knob, so the value between 4 and 150 bar stays untouched in operation.
• Pilot control keeps pressure stable across the whole flow range up to 580 l/min.
• Seat valve design closes tightly, which keeps leakage low.
• Maximum operating pressure of 350 bar in size 32.
• Two switching positions for pressure build-up and unloading, switched at 24 VDC.
• 6.49 kg weight at 580 l/min maximum flow.

Application

Suited to series power units, test benches and production cells with a defined process pressure. The concealed adjustment prevents the value from being altered during shift work. The solenoid unloads the circuit during standstill, and the NBR seals are rated for HL hydraulic fluid.
