The ZDBT-XA2-1X/160 081VV06P100N502K-AO-LOW pressure relief valve is produced by Bosch Rexroth within the ZDB Pressure Relief Valves series and limits system pressure in hydraulic automation circuits. It is built on nominal size 6, allowing installation in compact manifolds, and matches the ISO 4401-03-02-0-05 mounting interface so it can drop straight onto standard subplates. Fixing is handled by ISO 4762-M5-10.9 screws, while O-Ring 9.25 × 1.78 mm seals provide tight port connections. The unit can be set anywhere between 3 bar and 160 bar, and its body tolerates a maximum operating pressure of 350 bar. Hysteresis remains below 5 percent of the chosen setting to keep relief behavior consistent, and a maximum flow of 3 l/min suits pilot control branches that only need small discharge volumes.
The valve accepts HL or HLP hydraulic oils defined in DIN 51524, letting it work with common industrial fluids. Oil temperature may rise to 80 °C, ambient temperature can reach 70 °C during service, and storage is permitted up to 80 °C without compromising materials. The design supports installation in any position, giving machine builders freedom when orienting the block. Cleanliness must meet ISO 4406 code 20/18/15 so particles do not damage the seating surfaces. At 2.0 kg, the valve is light enough for single-person handling yet sturdy enough for continuous duty on hydraulic power units.
