The Bosch Rexroth ZDB6VB1-4X/100V (R900598152) is a high-performance pressure relief valve designed for hydraulic applications requiring precise pressure control and system protection. This model, part of the ZDB series, operates as a pilot-operated pressure relief valve in a sandwich plate design, making it suitable for integration into various hydraulic circuits.
This valve is engineered to maintain and limit system pressure to desired levels. It consists of a robust housing and one or two pressure valve cartridges, depending on the system's requirements. Pressure adjustments can be made easily through various adjustment types to ensure optimal performance within hydraulic systems.
The ZDB6VB1-4X/100V functions by remaining closed in its initial position until the pressure in channel A surpasses the preset value on the spring. Once this occurs, the pilot poppet opens, allowing hydraulic fluid to flow and consequently reducing pressure by moving the spool. This action opens the connection from A to T while preserving the set system pressure.
Furthermore, this model features an external pilot oil drain via channel T for efficient operation. It adheres to ISO porting patterns and can come with or without a locating hole for installation versatility. The valve offers different adjustment types including a rotary knob, sleeve with hexagon and protective cap, lockable rotary knob with scale, or a rotary knob with scale – all designed for user convenience in setting and maintaining desired pressures.
Constructed for durability and corrosion resistance, this Bosch Rexroth valve supports maximum operating pressures up to bar levels and can handle maximum flow rates measured in liters per minute (l/min). Its size and component series mark it as suitable for various circuit options within hydraulic systems. The ZDB6VB1-4X/100V is an essential component for any application that demands reliable pressure limitation within a hydraulic setup.

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.
