Pumpensicherheitsblock DBAW15BF2-2X/315Z6EG24NK4A08 - Bosch Rexroth R901481407

A motor that has to start against full pressure needs more breakaway torque than necessary. The pump safety block DBAW15BF2-2X/315Z6EG24NK4A08 unloads the pump through a built-on directional valve and switches to load only afterwards. It carries up to 300 l/min at a maximum operating pressure of 350 bar.

Benefits

• Solenoid unloading through a built-on directional valve at 24 VDC with two switching positions to symbol B.
• Up to 300 l/min in size 16 at a maximum operating pressure of 350 bar.
• Pressure adjustment range 6 to 315 bar through an internal hexagon covered by a protective cap against unauthorised adjustment.
• Pressure valve in poppet seat design, pilot-operated, for tight protection at rest.
• Flange connection, the directional valve sits on the ISO 4401-03-02-0-05 hole pattern.
• 7.6 kg with NBR seals for HL hydraulic fluid.

Technical data

Applications

The block sits directly at the pump outlet of power units in presses, test rigs and machine tools. There it covers two jobs at once, namely pressure protection of the circuit and electrical unloading during start-up and idle periods. Electrical connection is through a 3-pole connector (2 + PE) to EN 175301-803.
