***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth Z2DB10DD2-2X/200V (R901439552) is a mechanically actuated industrial hydraulic valve known for its high performance and reliability. This direct-acting pressure relief valve is designed in a sandwich plate configuration, ensuring seamless integration into various hydraulic systems. It features a variable spindle with an external hexagon and a variable screw, allowing precise adjustments to maintain system pressure within safe limits. The valve's spool symbol A ↔ B, B ↔ A indicates its capability to control flow direction efficiently. With a maximum pressure rating and the ability to accommodate a substantial flow rate, this valve is well-suited for demanding applications where consistent performance is critical. The Z2DB10DD2-2X/200V offers multiple ports for connectivity and comes with FKM seals compatible with a wide range of hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. Designed for quick and nearly leak-free response when relieving excess pressure from the system, the Z2DB10DD2-2X/200V includes an integrated damping feature in the control spool that ensures stability across varying flow rates. Its robust construction means it can withstand contamination in oil without loss of functionality. The valve arrives preset at the minimum pressure setting but can be adjusted as needed for specific applications via its adjustment type mechanism. The design also allows for pressure monitoring using a load cell on certain versions of the valve. This Bosch Rexroth valve adheres to international standards with some deviations noted in port labeling as per the data sheet provided. It offers various circuit options and corrosion protection designs tailored to extend service life even in harsh environments. With its combination of precision control and durable construction, the Z2DB10DD2-2X/200V is an essential component for maintaining efficient and safe hydraulic operations.

PRESSURE RELIEF VALVE -Z Z2DB10DD2-2X/200V

Size 10, symbol A - B and B - A, with manual actuation

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

Unpacked Weight: 3.020 kg

Sandwich plate valve Porting pattern according to ISO 4401-05-04-0-05 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 ZDB10D and Z2DB10D 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 and 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 version “MP”, the set system pressure can be recorded and monitored using a pressure load cell at the measuring port (5) (see dimensions)
