Pressure Relief Valve DBW10B1-5X/310S6EG24N9K4R12VE - Bosch Rexroth R901450552

This pilot-operated seat valve protects a hydraulic circuit against excess pressure. The adjustment range runs from 4 to 310 bar and is set on the rotary knob, flow reaches 200 l/min at an operating pressure of 350 bar maximum.

Benefits

• Pressure adjustment range of 4 to 310 bar on the rotary knob, so the setting is matched to the process without a tool
• Pilot-operated seat design, keeping the pressure deviation small across the flow range up to 200 l/min
• Electrical unloading through the 24 VDC solenoid, letting the pump idle without pressure during a pause
• 2 switching positions on 2 ports, subplate mounting to ISO 6264-06-09 in size 10
• FKM seals for wider fluid resistance, mass of 5.3 kg
• Connector, 3-pole (2 + PE) according to EN 175301-803 and CE conformity

Applications

The valve protects pumps and consumer circuits in machine tools, presses and test rigs. The solenoid unloads the circuit, which cuts idling losses at standstill. The rotary knob suits plants whose cut-off pressure is adjusted during operation.
