The Bosch Rexroth ZDB6DA2-2X/200V (R901423482) is a high-performance industrial hydraulic valve known for its reliable pressure relief capabilities. Designed with a variable spindle featuring an external hexagon, this direct-actuated valve includes a spool symbol A T and is capable of handling maximum pressures efficiently. It comes from the product group ID and is equipped with mechanical actuation, making it suitable for applications where precise pressure control is essential. The ZDB6DA2-2X/200V valve boasts a number of ports, with an interim assembly that adheres to NFPA T.. R D SizeCETOP D standards, as well as an ISO connection diagram. Its design allows for quick and nearly leak-free response to changes in system pressure, safeguarding hydraulic systems from potential overpressure damage. The seat design offers resistance against oil contamination, while the integrated damping in the control spool ensures stability across flow variations. This model arrives preset to the minimum possible pressure but can be adjusted according to specific requirements. When system pressure surpasses the set value, the control spool opens, allowing fluid to flow from channel P to channel T, thus maintaining the desired pressure level. Additional features include a variety of adjustment types such as spindle with hexagon, rotary knob, or lockable rotary knob with scale. The corrosion-protected design extends its durability in harsh environments. With a maximum operating pressure of bar and maximum flow rate of l/min, this sandwich plate valve conforms to international standards and offers optional circuit options for versatile application use. Seals made of FKM ensure compatibility with various hydraulic fluids like HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. The ZDB6DA2-2X/200V's robust construction and precise operation make it an essential component for industrial hydraulic systems requiring dependable pressure management.

PRESSURE RELIEF VALVE -Z ZDB6DA2-2X/200V

Size 6, symbol A - T, with manual actuation

Industrial hydraulic valve in a high performance range. Reliable pressure limitation to setting value

Unpacked Weight: 1.260 kg

Sandwich plate valve Porting pattern according to ISO 4401-03-02-0-05 4 pressure ratings, optional 3 adjustment types, optionally:
• Spindle with hexagon
• Rotary knob
• Lockable rotary knob with scale 5 circuit options Corrosion-protected design

Pressure valves of type ZDB6D and Z2DB6D are direct operated pressure relief valves in sandwich plate design.

The valves basically consist of housing (1) with seat (2) and control spool (3). The system pressure is set via the adjustment type (4).

The valves are closed in their rest position and protect a hydraulic system and its components against excessive pressures.

These valves respond quickly, noiselessly and in a virtually leakage-free manner. Thanks to the seat design, they are resistant against oil contamination. The integrated damping of the control spool (3) ensures extremely stable behavior,

as well as a low pressure increase with increasing flow.

In the state as delivered, the valves are set to the minimum possible pressure. The system pressure applied to channel P acts on the control spool (3). If the system pressure increases above the set value, the control spool (3) opens and the hydraulic fluid flows from channel P in channel T. This limits the system pressure to the set value.

For versions “MP”, “MA” and “MB”, the set system pressure can be recorded and monitored using a pressure load cell at the measuring port (5) (see dimensions)
