The Bosch Rexroth Z2DB6VD3-4X/315V (R900599175) is a high-performance pressure relief valve designed for controlling system pressure within hydraulic circuits. This sandwich plate valve is part of the ZDB series, which are pilot-operated valves featuring one or two pressure valve cartridges, depending on the specific application needs. The model is engineered to ensure reliable pressure limitation and is constructed with a robust housing that contains the essential valve components.
With its precise adjustability, the system pressure can be set accurately via an adjustment type selected based on user requirements. These adjustment types include options such as a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or a rotary knob with scale. The design of this model facilitates ease of use and maintains consistent pressure control.
The Z2DB6VD3-4X/315V operates by allowing hydraulic fluid to flow through the valve when the pressure exceeds a pre-set level determined by the spring tension. This process ensures that the connection from port A to port T opens to regulate and maintain system pressure without fluctuations.
This particular model features corrosion protection for enhanced durability in harsh environments and boasts compatibility with ISO porting patterns. It can be equipped either with or without a locating hole for flexible mounting options. The valve supports maximum operating pressures up to 315 bar and accommodates flow rates up to specified limits, ensuring efficient operation across various hydraulic applications.
This Bosch Rexroth valve is suitable for integration into diverse circuit options and offers versatility through its multiple cartridge and adjustment configurations. It provides reliable performance in controlling system pressures in hydraulic systems while ensuring safety and operational efficiency.

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.
