Pumpensicherheitsblock DBAWR40BF2-1X/200YS6EG24N9K4R12 - Bosch Rexroth R901159631

The Y in the type code marks the separate drain for pilot oil, which is why this block counts 3 ports instead of 2. It holds pump pressure in pilot-operated mode at a value between 3.7 and 200 bar and unloads through a built-on directional spool valve at 24 VDC.

Benefits

• Adjustment range 3.7 to 200 bar for working pressures in the middle band
• 3 ports, one of them dedicated to the separate pilot oil drain
• Flange connection in size 40, mass 14.72 kg
• Flow up to 450 l/min at a maximum operating pressure of 350 bar
• Solenoid unloading with 2 switching positions at 24 VDC, connector 3-pole (2 + PE) according to EN 175301-803

Application

The block serves power units whose pilot oil drain has to run separately into the tank, for instance because of back pressure in the return line. An adjustment range up to 200 bar covers medium presses and test rigs. Solenoid unloading lets the system start without pressure.
