Pressure Relief Valve DBW30B3-5X/315S6EG24N9K4R12 - Bosch Rexroth R901208940

The DBW30B3-5X/315S6EG24N9K4R12 limits the pressure of a circuit carrying up to 650 l/min to the value set. The adjustment range runs from 4 to 315 bar and is changed on a lockable rotary knob with a scale. At 4.5 kg the assembly stays easy to handle inside the manifold.

Benefits

• Adjustment range of 4 to 315 bar at a maximum operating pressure of 350 bar
• 650 l/min relief capacity in size 32
• Weight of 4.5 kg, so it can be fitted into the manifold without lifting gear
• Lockable rotary knob with a scale for a traceable setting
• Pilot-operated seat valve, which keeps leakage low in the closed state
• Solenoid unloading at 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803

Applications

It typically sits in power units and control manifolds of presses and test rigs running a system pressure of up to 315 bar. Electrical unloading takes load off the drive during start-up. Interface and dimensions follow size 32.
