Pumpensicherheitsblock DBAW15BF2-2X/130S6EG24N9K4E - Bosch Rexroth R901534962

The outlet of a pump has to be limited in pressure and it has to start without load. This pilot-operated safety block in size 16 does both in one housing, it limits up to 250 l/min to a value set between 6 and 130 bar and unloads the pump to tank through a built-on directional spool valve.

Benefits

• Setting range of 6 to 130 bar, the adjustment screw sits in an internal hexagon under a protective cap and stays safe from accidental changes
• Flow of up to 250 l/min at an operating pressure of 350 bar maximum
• Solenoid unloading on 24 VDC across two switching positions, so the pump starts against no back pressure
• Pressure stage in poppet seat design, which keeps leakage low in the closed state
• Flange connection and interface ISO 4401-03-02-0-05 for the mounted directional valve, NBR seals and a mass of 6.04 kg

Applications

The block sits directly behind the pump on power units of presses, injection moulding machines and test rigs. The unloading solenoid lets the installation start unpressurised and lets it be depressurised at the end of a cycle. Rating for HL fluid suits common industrial units running on mineral oil.
