The Bosch Rexroth DB 6 DPW2-1X/160V (0811105216) is a direct operated pressure relief valve designed for subplate mounting, offering precise control in hydraulic systems by limiting system pressure. This valve includes a main valve with a spool insert and an adjustable pressure element, allowing for customization and adaptability to specific application requirements. The operation of the DB 6 DPW2-1X/160V involves hydraulic fluid pressure acting on the main spool, triggering the poppet to open against the spring when the set pressure is exceeded, thus enabling fluid flow from channel P to T through the control edge. For user convenience and accuracy in pressure adjustments, this model provides three options for the pressure adjustment element: a sleeve with an internal hexagon, a lockable rotary knob with scale, and a standard rotary knob with scale. This versatility ensures that users can select the most suitable adjustment mechanism for their operational needs. The robust design of this valve ensures reliable performance in various hydraulic applications where precise pressure relief is critical.
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.
