The ZDBT-XP2-1X/160 081VV06P100N502K-AO-HIGH valve belongs to the ZDB Pressure Relief Valves series from Bosch Rexroth. It limits system pressure in hydraulic automation by opening to tank when the threshold is reached. The size 6 sandwich plate construction fits between standardized subplates and adjoining directional valves while maintaining the porting pattern ISO 4401-03-02-0-05. The unit is pilot-operated with an external pilot drain routed through port T. It tolerates operating and set pressures up to 315 bar and controls flow rates to 60 l/min. Counter pressure at the tank line can reach 40 bar without affecting stability.
Installation is flexible because the valve works in any orientation and uses M5 mounting screws that engage locating holes of 4 mm on the component side and 3 mm on the plate side. A hex plug with a 24 mm wrench flat requires 50 Nm tightening torque to secure the adjustment assembly. System cleanliness must comply with ISO 4406 (c) 20/18/15, and the hydraulic fluid shall conform to DIN 51524 mineral-oil standards. These conditions preserve internal clearances and keep pressure response predictable.
