Pressure Relief Valve DBW30A7N5X/315S6EG24N9K4R12 - Bosch Rexroth R901044141

This pilot-operated relief valve in size 32 is set on a rotary knob with a scale, so the chosen value can be read at the device. The adjustment range runs from 4 to 315 bar, the valve relieves up to 650 l/min and carries spool symbol A.

Benefits

• Rotary knob with a scale, so the pressure setting can be read without a gauge
• Adjustment range of 4 to 315 bar at a maximum operating pressure of 350 bar
• 650 l/min relief capacity to the ISO 6264-10-17 interface
• Pilot-operated seat valve with two ports and spool symbol A
• Electrical unloading through the solenoid at 24 VDC
• Subplate mounting, NBR seals, weight 5.85 kg

Applications

The valve protects pump circuits in power units where the limiting pressure is changed while running, for instance in test rigs and experimental set-ups. The scale on the knob makes every change traceable. The solenoid lets the circuit go pressureless between two runs.
