Pumpensicherheitsblock DBAW30BH2-2X/270ZZ6EG24N9K4A00E - Bosch Rexroth R901085588

In plant with long holding phases, leakage of the pressure valve decides how often the pump has to top up. The DBAW30BH2-2X/270ZZ6EG24N9K4A00E pump safety block therefore uses a pilot-operated pressure valve in poppet seat design and covers 6 to 270 bar.

Benefits

• Pressure valve in poppet seat design, which keeps leakage low during the holding phase.
• Pressure adjustment range 6 to 270 bar at a maximum operating pressure of 350 bar.
• Up to 300 l/min across two ports on the high-pressure flange, size 32.
• Solenoid unloading at 24 VDC, symbol B, two switching positions.
• NBR seals for HL hydraulic fluid and a connector 3-pole (2 + PE) according to EN 175301-803.
• 8.46 kg mass, CE conformity.

Technical data

Applications

Clamping hydraulics and presses that hold pressure for minutes or hours are the typical cases. Because the seat valve passes almost no oil when closed, the pump cuts in less often. Solenoid unloading additionally allows a controlled move into pressureless circulation.
