Function and Section of ZDB Pressure Relief Valve
Initial Position:
- Initially, the valves remain closed.
- Pressure in channel A acts upon the spool (1).
Pressure Mechanism:Pressure is applied to the spring-loaded side of the spool (1) via nozzle (2), and to the pilot poppet (6) via nozzle (3).
Activation:
- When the pressure in channel A surpasses the value set by the spring (5), the pilot poppet (6) opens.
- Hydraulic fluid then flows from the spring-loaded side of the spool (1) through nozzle (3) into channel T.
- This pressure drop shifts the spool (1), opening the connection from A to T, thereby maintaining the pressure set by the spring (5).
Pilot Oil Drainage:The pilot oil is externally drained from the two spring chambers via channel T.
Basic Structure:The ZDB and Z2DB types are pilot-operated pressure relief valves designed in a sandwich plate configuration, ensuring efficient pressure management.

Q: Can Bosch Rexroth ZDB valves be used with directional spool valves?
A: Yes, directional spool valves can be used with Bosch Rexroth ZDB valves to enhance the control system by providing both direction and pressure control within hydraulic systems.
Q: What are the standard sizes of Bosch Rexroth® pressure valves such as Z2DB 6 and Z2DB 10?
A: The size of the Bosch Rexroth pressure valves, like the Z2DB 6 and Z2DB 10, describes them. The smaller-sized one, which is Z2DB 6 is commonly used where there are lower flow rates while its counterpart, the larger one, referred to as Z2DB 10 is usually used for high flow rate conditions.
Q: How does a solenoid-operated valve work in a hydraulic system?
A: Solenoid-operated valves operate through an electrical solenoid that controls the valve mechanism. When energized, it moves the spool or seat to enable fluid flow or blockage, respectively, allowing electronic manipulation of hydraulic systems with great accuracy.
Q: What do you mean by pressure sequence valves, and does Bosch Rexroth offer them?
A: The operation sequence of hydraulic circuits is controlled using a pressure sequence valve that opens according to a predetermined pressure setting. These have been among the various types of control components for hydraHydraulicsided by Bosch Rexroth.
Q: In what way do isolator valves work in hydraulic systems?
A: Isolator valves separate sections within a hydraulic circuit, permitting maintenance and regulation without shutting down everything. This ensures safety and efficiency during operations.
Q: What should you consider when selecting a hydraulic valve such as the Bosch Rexroth®ZDB for your system?
A: When considering some crucial parameters like the system’s pressure requirements, flow rate, compatibility with other devices such as directional spool valve check valves, etc., and specific applications (e.g., rotation of hydraulic actuators), it can help to know what matters most in making the right choices regarding hydraulic valves like ZDB manufactured by Bosch Rexroth.
