The Bosch Rexroth ZDBT-XP3-1X/160 (0811104116) is a precision-engineered pressure relief valve designed for effective system pressure limitation in hydraulic systems. This remote control valve features a seat design and is primarily used to maintain the desired pressure within a hydraulic circuit by limiting the system pressure. It operates manually through an adjustment mechanism, allowing for precise user control over the pressure settings. The construction of this valve includes a robust housing, a responsive valve poppet, and a corresponding valve seat, ensuring reliable operation and durability. In its default state, the valve poppet is seated firmly against the valve seat, creating a seal that prevents fluid flow between the P (pressure inlet) and T (tank) connections. The system's hydraulic force acts against this seal; when it reaches the force preset by the adjustment mechanism, the valve activates to regulate pressure. Upon reaching the set threshold, the ZDBT-XP3-1X/160 allows excess fluid to bypass from P to T by lifting off the poppet from its seat. This action enables it to maintain system stability by relieving excess pressure in a controlled manner. Additionally, when there is no load on its spring, there is a minimum guaranteed pressure of 3 bar due to spring preload force. This model is specifically intended for use as a pilot control valve in applications requiring indirect control of large fluid flows. Its design facilitates installation on subplates or within control panels, making it versatile for various hydraulic system configurations. The ZDBT-XP3-1X/160 exemplifies high-quality engineering suitable for precise control in complex hydraulic systems.

Pressure relief valves of type DBT are remote control valves with seat design and are used for limiting a system pressure.

The setting is completed manually, via the adjustment type (4).

The valves basically consist of the housing (1), the valve poppet (2) and the related valve seat (3).

In the unloaded position, the valve poppet (2) pushes onto the valve seat (3) and blocks the connection between P and T connection.

If the hydraulic force equals the force set at the adjustment type (4), the valve controls the set pressure.

By lifting off the valve poppet (2) from the valve seat (3), the excessive hydraulic fluid may flow off from P to T.

With completely unloaded spring (5), the minimum pressure of 3 bar (spring preload force) will settle.

These valves are basically used as pilot control valves for the indirect control of larger flows.
