The ZDBT-XP3-1X/160 081VV06P100N502F-AO-HIGH pressure relief valve belongs to the ZDB Pressure Relief Valves series and is manufactured by Bosch Rexroth. As a direct-operated seat valve, it limits hydraulic pressure to protect automation circuits from overload. The maximum operating pressure is 350 bar, allowing the component to perform in medium-pressure systems, while the maximum setting pressure of 160 bar and the minimum setting pressure of 3 bar give a broad adjustment range for different duty points. A sandwich plate mounting style that uses the ISO 4401-03-02-0-05 interface lets the valve fit between subplates without additional piping. The nominal size of 6 defines the flow path and aligns with common manifold cavities, and a mass of 2.0 kg makes handling straightforward during installation.
The valve is intended for mineral oil HL or HLP fluids specified in DIN 51524, ensuring compatibility with standard power units. To avoid seat damage, the hydraulic medium should meet cleanliness class ISO 4406 20/18/15. A maximum flow of 3 l/min suits pilot circuits and small actuators that require precise pressure control. The return port T is designed to discharge unpressurized to tank so the spring chamber can vent freely and maintain stable relief characteristics. These parameters work together to provide reliable overpressure protection in compact hydraulic automation assemblies.
