Pressure Relief Valve DBW30B1N5X/140-6EG24N9K4E - Bosch Rexroth R901337108

Anyone running one hydraulic circuit for several tools has to change the cut-off pressure without rebuilding it. This pilot-operated pressure relief valve is set at a rotary knob from 4 to 140 bar and discharges up to 580 l/min through the size 32 subplate connection.

Benefits

• Rotary knob with a setting range of 4 to 140 bar, so the value can be changed between jobs without tools.
• Pilot-operated design keeps the set pressure stable across the full flow range up to 580 l/min.
• Seat valve that closes tightly in the rest position.
• Maximum operating pressure of 350 bar as the body limit above the setting range.
• Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803.
• 6.49 kg weight in size 32.

Application

Intended for power units in forming and assembly lines where several tools need different pressures. The solenoid drops the circuit to zero pressure between cycles. Approval for HL fluid and the NBR seals suit mineral oil systems in the usual temperature band.
