The Bosch Rexroth ZDB6VP2-4X/315V (R900409898) is a high-performance industrial hydraulic valve designed for precise pressure relief regulation within hydraulic systems. This pilot-operated spool valve features a variable spindle with an external hexagon, allowing for easy adjustment and setting of system pressure to the desired value. It is equipped with a variable screw also featuring an external hexagon for additional fine-tuning capabilities.
The ZDB6VP2-4X/315V is characterized by its robust sandwich plate design, which includes one or two pressure valve cartridges, depending on the specific application requirements. The valve operates by utilizing the system pressure in channel A to act on the spool, while also applying pressure to the spring-loaded side via nozzles. This mechanism ensures that when the preset pressure level is exceeded, the pilot poppet opens to allow hydraulic fluid flow and consequent pressure relief from A to T.
This model comes with various adjustment types for pressure settings, including options such as a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or a rotary knob with scale for precise control. The device offers corrosion protection and conforms to ISO porting patterns for seamless integration into existing systems.
With a size of CETOP D and component series X, this Bosch Rexroth valve can withstand maximum operating pressures up to 315 bar and handle maximum flow rates of l/min, making it suitable for demanding industrial applications where reliable performance is critical. Its connection diagram adheres to NFPA standards ensuring compatibility and ease of installation.
Designed for versatility in application, the ZDB6VP2-4X/315V supports various hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. Its seals are made from FKM material offering excellent resistance against harsh fluids. The unit's weight and dimensions are optimized for interim assembly configurations providing flexibility in system design.

Industrial hydraulic valve in a high performance range. Reliable pressure limitation to setting value
Unpacked Weight: 1.16 kg
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.
