The Bosch Rexroth DB 6 DPW3-1X/315V (0811105223) is a direct operated pressure relief valve designed for subplate mounting and is an essential component in hydraulic systems for controlling and limiting system pressure. This valve functions by employing a main valve with a spool insert and an adjustable pressure element that responds to changes in system pressure. When the pressure at channel P rises above the preset level on the spring, the poppet is actuated, allowing the main spool to move and enabling hydraulic fluid to flow from channel P to T through the control edge, effectively reducing the excess pressure. To accommodate various application requirements, this model offers three options for adjusting the system pressure: a sleeve with an internal hexagon, a lockable rotary knob with a scale, and a non-lockable rotary knob also equipped with a scale. These features provide flexibility and precision in setting and maintaining desired pressure levels within hydraulic systems. The robust design of this Bosch pressure relief valve ensures reliable performance in regulating hydraulic pressures, thereby protecting system components from potential damage due to over-pressurization.

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.
