Pumpensicherheitsblock DBAW15BF2D2X/315ZZ6EG24N9K4A00 - Bosch Rexroth R901553469

A pump has to be protected against overload, and during breaks it should circulate unloaded so the oil is not heated for nothing. The DBAW15BF2D2X/315ZZ6EG24N9K4A00 pump safety block in size 16 covers both tasks in one component and works up to 300 l/min at a maximum operating pressure of 350 bar.

Benefits

• Pressure adjustment range 6 to 315 bar via an internal hexagon screw with a protective cap.
• Solenoid unloading through a built-on directional spool valve with 24 VDC supply voltage, two switching positions, symbol B.
• Pilot-operated pressure valve in poppet seat design, which keeps leakage low in the closed state.
• Up to 300 l/min at a maximum of 350 bar with two ports as a flange connection.
• NBR seals for HL hydraulic fluid, electrical connection through a connector, 3-pole (2 + PE) according to EN 175301-803.
• 5.8 kg mass with connection diagram ISO 4401-03-02-0-05 for the built-on directional valve.

Applications

The block sits directly at the pump outlet of hydraulic power units, presses and machine tools. While the solenoid is energised the valve holds the set pressure, and once it is switched off the pump circulates to tank through the unloading path. That cuts drive power during idle phases and keeps the oil temperature down.
