ZDBT-XA8-1X/160 081VV06P100N502H-AO-LOW

The ZDBT-XA8-1X/160 081VV06P100N502H-AO-LOW valve belongs to the ZDB Pressure Relief Valves series and is manufactured by Bosch Rexroth for hydraulic automation circuits that must vent excess pressure quickly. With a nominal size of 6, it occupies minimal manifold space while handling localized pilot flows. The body attaches by subplate mounting, and its porting pattern matches ISO 4401-03-02-0-05 to streamline manifold design. Four M5 screws to ISO 4762 clamp the unit securely, and the installation position may be any orientation without performance loss. The assembly manages a maximum flow of 3 L/min suitable for low-volume relief passages, and its return flow is routed depressurized to tank to prevent back-pressure interaction with system drains. A weight of 2.0 kg allows technicians to install or remove the valve by hand during service.

The adjustable range starts at a minimum set pressure of 3 bar and extends to a maximum set pressure of 160 bar, letting operators tailor relief points for delicate actuators or moderate-pressure branches. Structural integrity supports a maximum operating pressure of 350 bar so the valve resists transient spikes common in high-duty cycles. Mineral oil in the HL or HLP categories is the specified hydraulic fluid, and system cleanliness must reach class 20/18/15 per ISO 4406 to avoid spool sticking or seat erosion. Sealing between pressure and tank ports relies on O-rings sized Ø9.25 × 1.78 mm to keep leakage low throughout repetitive cycling. These parameters equip the valve to deliver reliable, adjustable over-pressure protection while maintaining fluid compatibility and contamination control inside automated hydraulic machinery.
