Description
A pressure valve in poppet seat design closes tightly instead of leaking across a spool clearance. The pump safety block DBAW15BF2-2X/315ZZ6EG24N9K4A08 uses that design, limits pressure between 6 and 315 bar and mounts to the power unit through a flange connection.
Benefits
- Pilot-operated pressure valve in poppet seat design, the held pressure stays up even across longer standstills.
- Pressure adjustment range 6 to 315 bar behind an internal hexagon with a protective cap.
- Flange connection and a built-on directional spool valve to ISO 4401-03-02-0-05.
- 300 l/min at size 16, two ports in two switching positions.
- Solenoid unloading at 24 VDC, maximum operating pressure 350 bar.
- 7.92 kg, NBR seals for HL hydraulic fluid.
Applications
In clamping systems and holding circuits what counts is how long a pressure stands without the pump cutting in again. The poppet seat design of the pressure stage supports that, while electrical unloading takes the power unit off load during idle phases. Both functions sit in one housing and save a second assembly inside the unit.
Manufacturer
Bosch Rexroth, material number R900944179, product family DBA.15,25,30. The built-on directional valve follows port pattern ISO 4401-03-02-0-05.
