DBT-XP7-1X/160 081VV06P100N502E-AO

The DBT-XP7-1X/160 081VV06P100N502E-AO valve belongs to the DB Pressure Relief Valves series and is manufactured by Bosch Rexroth for hydraulic automation where circuit pressure must be limited. It uses nominal size 6 passages so it fits compact manifolds without requiring large porting. The pressure stage of 160 bar defines the spring range that can be adjusted for most medium-pressure systems. A maximum operating pressure of 350 bar prevents overloading of downstream components when pressure spikes occur. The minimum set pressure is 3 bar, allowing the valve to protect low-pressure test circuits as well. These limits let machine designers cover a wide span of operating pressures with one cartridge.

For installation, the valve follows the ISO 4401-03-02-0-05 interface so it bolts directly to standard subplates using four M5 × 50 screws rated to ISO 4762-10.9, which maintain clamp force under high pressure cycling. The return port T is routed unpressurized to tank so redirected oil does not raise back-pressure that could alter the setting. Maximum flow is 3 l/min, making the unit suitable for pilot circuits or small actuators where precise limiting is required. A cleanliness level of ISO 4406 (c) 20/18/15 must be maintained to avoid spool wear, and operation is specified with mineral oil HL or HLP per DIN 51524 for proper lubrication. The assembly weighs 2.0 kg, light enough for mounting on mobile equipment manifolds.
