Pressure Relief Valve DBW30B1N5X/150S6EG24NK4R12VE - Bosch Rexroth R901059699

A hydraulic power unit needs a pressure stage that can be set by hand and switched off electrically. The DBW30B1N5X/150S6EG24NK4R12VE limits system pressure within a range of 4 to 150 bar, passes up to 580 l/min and unloads the circuit through a 24 V DC solenoid.

Benefits

• Adjustment range 4 to 150 bar at the rotary knob, reset without tools.
• 580 l/min across two ports at a maximum operating pressure of 350 bar.
• Seat valve in size 32 to connection diagram ISO 6264-10-17, pilot-operated.
• Electrical unloading at 24 V DC through a 3-pole connector (2 + PE) to EN 175301-803.
• 5.85 kg weight, FKM seals, CE conformity.

Application

The valve sits at the pump outlet of power units that should circulate unloaded between cycles. Seat design keeps leakage low when the set pressure stands for long periods.

Manufacturer

Bosch Rexroth lists the valve under material number R901059699 in product family DB.10-30, data sheets RE 25802 and RE 25802-B.
