Pressure Relief Valve DBW30BG1-5X/315-6EG24N9K4/12 - Bosch Rexroth R901156836

When the pressure limit of a machine is adjusted regularly, access to the setting matters. This pilot-operated size 32 relief valve is set on a rotary knob between 3.8 and 315 bar and relieves up to 650 l/min. A mounted directional spool valve with a 24 VDC solenoid unloads the circuit on a command from the control system.

Advantages

• Pressure set on a rotary knob, range 3.8 to 315 bar
• Flow up to 650 l/min at a maximum operating pressure of 350 bar
• Solenoid unloading through a mounted directional spool valve on 24 VDC, two switching positions
• Poppet seat pressure stage, connection diagram ISO 6264-10-17
• Threaded connection with two ports, weight 6.54 kg
• Connector, 3-pole (2 + PE) to EN 175301-803, NBR seals for HL hydraulic fluid

Application

Power units in special machinery, presses and hydraulic clamping systems use the valve as their system pressure limit. The rotary knob helps during commissioning and retooling because the value changes without a tool. Through the 24 VDC solenoid the pump idles at almost no pressure during breaks.

Manufacturer
