Pressure Relief Valve DBW30B1-5X/315X6EG24N9DAL/12 - Bosch Rexroth R978914628

A power unit with a large displacement needs protection that can take the full pump flow. This pilot-operated pressure relief valve in size 32 discharges up to 650 l/min and is set at the rotary knob within a range of 4 to 315 bar.

Advantages

• 650 l/min maximum flow in size 32
• Setting range 4 to 315 bar at the rotary knob without tools
• 350 bar maximum operating pressure
• Electrical unloading through a 24 VDC solenoid, spool symbol B
• Poppet seat design with tight closure in the unloading position
• Port pattern ISO 6264-10-17, 6.3 kg weight, NBR seals

Application

The valve sits directly behind the pump of a hydraulic power unit as system protection. The solenoid circulates the pump without pressure during start-up or idle periods. The rotary knob allows quick adjustment of system pressure between 4 and 315 bar.
