The Bosch Rexroth Z2DB6VD2-4X/200-120V (R900575577) is a pilot-operated pressure relief valve designed with a sandwich plate configuration for efficient system pressure limitation. This valve is part of the sophisticated ZDB series, which is engineered to maintain system pressure by utilizing one or two pressure valve cartridges housed within its robust structure. The adjustment type available on this model allows for precise setting of the system pressure to meet application requirements.
In its default state, the Z2DB6VD2-4X/200-120V valve remains closed until the pressure in channel A surpasses a predefined level set by an adjustable spring. Upon reaching this threshold, the pilot poppet activates, allowing hydraulic fluid to flow through and reduce the spool's spring-loaded side, thus establishing a connection from A to T while sustaining the set pressure. Notably, this model ensures that pilot oil drainage from spring chambers is directed externally via channel T.
The versatility of this Bosch Rexroth valve is further exemplified by its compatibility with various adjustment types for pressure settings, including options like a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, and rotary knob with scale. Additionally, it offers corrosion protection and adheres to ISO porting patterns which may include an optional locating hole.
This particular model features size 6 design specifications and belongs to component series X. It can withstand a maximum operating pressure of up to 350 bar and can handle maximum flow rates up to 80 l/min. The Z2DB6VD2-4X/200-120V valve is suitable for applications requiring precise control over hydraulic system pressures while ensuring reliability and durability in operation.

Pressure valves of type ZDB and Z2DB are pilot-operated pressure relief valves in sandwich plate design.
They are used for limiting a system pressure.
The valves basically consist of the housing (7) and one or two pressure valve cartridges.
The system pressure can be set via the adjustment type (4).
Example version "VA":
In the initial position the valves are closed. The pressure in channel A acts on the spool (1). At the same time, pressure is applied to the spring-loaded side of the spool (1) via nozzle (2) and to the pilot poppet (6) via nozzle (3). If the pressure in channel A exceeds the value set at the spring (5), the pilot poppet (6) opens.
Hydraulic fluid flows from the spring-loaded side of the spool (1), nozzle (3), channel (8) into channel T. The resulting pressure drop moves the spool (1) and thus opens the connection from A to T while maintaining the pressure set at spring (5).
Die pilot oil drain from the two spring chambers is effected externally, via channel T.
