The Bosch Rexroth Z2DB6VC2-4X/315V (R900411318) is a high-performance industrial hydraulic valve designed for reliable pressure relief up to its set value. This pilot-operated spool valve, with a sandwich plate design, is specifically tailored for limiting system pressures within hydraulic applications. It features a mechanically actuated control mechanism and comes equipped with two pressure valve cartridges. The Z2DB6VC2-4X/315V can be adjusted via various methods including a rotary knob, sleeve with hexagon and protective cap, or a lockable rotary knob with scale, ensuring precise pressure settings.
This model has a maximum operating pressure of 315 bar and can handle maximum flow rates of up to l/min, suitable for demanding hydraulic systems. It boasts an array of connection options including NFPA T.. R D SizeCETOP D and ISO standard porting patterns, which facilitate versatile integration into existing setups. The valve is designed to accommodate numerous types of hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. Its FKM seals ensure robust performance in diverse operating conditions.
The Bosch Rexroth Z2DB6VC2-4X/315V valve operates by utilizing system pressure in channel A to act on the spool while simultaneously applying pressure to the pilot poppet through nozzles. Excess pressure causes the pilot poppet to open allowing fluid flow from A to T while maintaining the pre-set spring tension. This action ensures that the connection from A to T opens only when necessary to relieve excess system pressure.
Constructed for longevity and reliability in industrial environments, the corrosion-protected design adds durability against harsh conditions. This model's versatility is further enhanced by its ability to be used with one or two pressure valve cartridges and its compatibility with various circuit options. The Bosch Rexroth Z2DB6VC2-4X/315V is an essential component for sophisticated hydraulic systems requiring precise control over their operational pressures.

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.
