The Bosch Rexroth Z2DB10VD2-4X/200 (R900440550) is a high-performance industrial hydraulic sandwich plate valve designed for reliable pressure relief at set pressures. It is a mechanically actuated valve featuring spool symbols for A to B and B to A flow control. With maximum pressure capabilities and a product group ID, this valve includes multiple ports and is actuated mechanically.
The Z2DB10VD2-4X/200 has a maximum flow rate specification and employs various types of connections, including interim assembly options. It adheres to connection diagram standards set by NFPA T.. R D SizeCETOP D and ISO, ensuring compatibility with a range of systems. The valve offers different switching positions and comes with a weight specification for ease of integration into hydraulic systems.
Seals made from NBR ensure the durability of the valve when used with hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC. The Z2DB series valves consist of a housing and one or two pressure valve cartridges that allow users to set system pressure through an adjustment type mechanism.
In its default state, the valve remains closed until the system pressure in channel A surpasses the spring-set value, prompting the pilot poppet to open and enabling fluid flow which adjusts the spool position accordingly. This action opens the connection from A to T TA until equilibrium is reached at the spring-set pressure level.
The Z2DB10VD2-4X/200 provides several adjustment options for setting pressure including rotary knobs (with or without scales), sleeves with hexagon shapes and protective caps, or lockable rotary knobs with scales. Its corrosion-protected design ensures longevity even in harsh environments. Additionally, it offers flexibility with either one or two pressure valve cartridges and comes in size 10 with component series X capable of handling maximum operating pressures up to bar levels while accommodating maximum flow rates measured in liters per minute (l/min).

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).
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) and channel (8) into channel T (TA). The resulting pressure drop moves the spool (1) and opens the connection from A to T (TA). In channel A, the pressure set at the spring (5) settles.
