Pumpensicherheitsblock DBAW15BF3-2X/315Z6EG24N9K4A08 - Bosch Rexroth R901273007

Two jobs in one block, protecting the pump outlet and unloading it during circulation, are handled here by a built-on directional spool valve together with a pressure stage in poppet seat design. Setting runs between 6 and 315 bar on a lockable rotary knob with scale, which secures the value against unauthorised adjustment. The block uses a flange connection and passes up to 300 l/min.

Benefits

• Setting range of 6 to 315 bar on a lockable rotary knob with scale
• Solenoid unloading through a built-on directional spool valve lets the pump idle without pressure
• Pressure stage in poppet seat design, pilot-operated, maximum operating pressure 350 bar
• Flow up to 300 l/min, flange connection instead of subplate mounting
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• FKM seals for HL hydraulic fluid, mass 7.86 kg

Application

The block is flanged straight onto the pump outlet of a power unit and covers protection and unloading in a single part. Between two working strokes the pump circulates without pressure, which cuts lost power and oil temperature. The lockable rotary knob keeps the chosen pressure stage in place.
