The Bosch Rexroth DB 6 DPBW3-1X/80VW65 (0811105230) is a direct operated pressure relief valve designed to maintain and limit system pressure within hydraulic systems. This valve features a main valve with a spool insert and an adjustable pressure element, allowing for precise control over the system's pressure threshold. Upon reaching the set pressure, as determined by the spring tension, the poppet opens against the spring force, enabling the main spool to move and allowing hydraulic fluid to flow from channel P to T, effectively relieving excess pressure. The unit is engineered for subplate mounting and offers three options for adjusting the pressure: a sleeve with an internal hexagon, a lockable rotary knob with a scale, and a rotary knob with scale. These adjustment mechanisms provide versatility and ease of use in various application settings. The Bosch Rexroth DB 6 DPBW3-1X/80VW65 valve ensures reliable operation and is instrumental in protecting hydraulic circuits from overpressure situations by providing a controlled flow path for excess fluid, thus safeguarding components from potential damage due to excessive force or strain.
General
Pressure valves of type DB 6 D are direct operated pressure relief valves.
They are used for limiting the system pressure.
The pressure relief valves basically consist of the main valve (1) with main spool insert (2) and the pressure adjustment element (3).
The pressure applied to channel P acts on the main spool (2).
If the pressure in channel P exceeds the value set at the spring (5), the poppet (4) opens against the spring (5) and the main spool (2) is free to move accordingly against the spring. So hydraulic fluid flows over the control edge (6) out of channel P to T.
