The Bosch Rexroth ZDB6VP2-4X/200 (R900428339) is a high-performance industrial hydraulic valve designed for reliable pressure relief up to its setting value. This mechanically actuated valve falls within the product group ID of pilot-operated pressure relief valves and features a spool symbol P T. It is capable of handling a maximum pressure and is equipped with NBR seals, ensuring compatibility with hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC.
The ZDB6VP2-4X/200 valve has a sandwich plate design according to ISO standards and can be used in various circuit options. It offers flexibility with one or two pressure valve cartridges and multiple adjustment types for setting system pressure, including a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or rotary knob with scale. The corrosion-protected design enhances its durability for sustained use in harsh environments.
This model's size corresponds to CETOP D standards for easy integration into existing systems. The maximum operating pressure is bar while the maximum flow rate it can handle is l/min. Its porting pattern complies with ISO specifications and may include an optional locating hole.
The ZDB6VP2-4X/200 operates by utilizing the system pressure on channel A to actuate the spool through an external pilot oil drain via channel T. In its default state, the valve remains closed until the preset spring value is exceeded, allowing fluid to flow from channel A to T while maintaining control over the set pressure.
With its robust construction and precise control features, this Bosch Rexroth hydraulic valve ensures efficient operation in industrial settings requiring dependable pressure regulation.

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.
