The Bosch Rexroth ZDB6VP7-4X/200V (R900503154) is a high-performance pressure relief valve designed for hydraulic applications that require precise control of system pressure. This valve is a pilot-operated relief valve in a sandwich plate design, which allows for easy installation and maintenance. It features one or two pressure valve cartridges housed within a robust housing, ensuring durability and reliable performance.
The ZDB6VP7-4X/200V is engineered to limit system pressure by allowing the user to set the desired level via an adjustment type, which can be tailored to specific requirements. The initial position of the valves is closed, with the system pressure acting on the spool. Pressure exceeding the set value causes the pilot poppet to open, allowing hydraulic fluid to flow and maintain the set pressure.
This model comes with various adjustment types for pressure setting, including a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale. Its corrosion-protected design ensures longevity even in harsh working environments. The sandwich plate valve features porting patterns according to ISO standards and can be ordered with or without a locating hole.
With its size and component series X designation, this Bosch Rexroth valve can handle maximum operating pressures up to 350 bar and maximum flow rates of up to 80 l/min. The external pilot oil drain from the spring chambers via channel T contributes to its efficient operation. This versatility makes it suitable for various circuit options and applications where reliable pressure control is critical.

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.
